Operator

Good day, and thank you for standing by. Welcome to the Endo International plc First Quarter 2021 Earnings Conference Call. [Operator Instructions] Please be advised, today's conference is being recorded. [Operator Instructions]

I would now like to hand the conference over to speaker today, Laure Park, Senior Vice President of Investor Relations and Corporate Affairs. Please go ahead.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thank you. Good morning, and thank you for joining us to discuss our first quarter 2021 financial results. Joining me on today's call are Blaise Coleman, President and CEO of Endo; Mark Bradley, Executive Vice President and Chief Financial Officer; and Patrick Barry, President, Global Commercial Operations.

We have prepared a slide presentation to accompany today's webcast and that presentation as well as other materials are posted online in the Investors section at endo.com. I would like to remind you that any forward-looking statements made by management are covered under the US Private Securities Litigation Reform Act of 1995 and the applicable Canadian securities laws and are subject to the changes, risks and uncertainties described in the press release and in our U.S. and Canadian securities filings.

In addition, during the course of this call, we may refer to non-GAAP financial measures that are not prepared in accordance with accounting principles generally accepted in the United States and that may be different from non-GAAP financial measures used by other companies.

The reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures are contained in our earnings press release issued last night, unless otherwise noted therein.

I would now like to turn the call over to Blaise. Blaise?

Blaise Coleman -- President and Chief Executive Officer

Thank you, Laurie, and good morning, everyone, and thank you for joining us this morning. I'm proud of the way our Endo team executed this quarter across all parts of our business. We delivered better-than-expected first quarter results, continue to make progress against our strategic priorities, including the achievement of an important milestone with the launch of Qwo in March, and maintained our relentless focus on transforming our business in order to deliver long-term value for all of our stakeholders.

Before moving to further review of the quarter, I want to recognize the ongoing challenges of COVID-19 in many parts of the world, including in India, where many of our team members live and work. To provide for the continued safety of our team members, we've expanded our safety protocols and support services and are working to provide vaccines and treatment services if needed. Additionally, we are making donations to assist with the release efforts in India, including donations to the Indian Red Cross. On behalf of our Endo team members, I want to express our deepest sympathies to those who have been affected by the ongoing COVID-19 pandemic in India.

If we move to the agenda on Slide 2, I will start with our strategic priorities, followed by a discussion of our first quarter business performance and an update on our pipeline, then Mark will address our first quarter financial results and provide updates on our financial expectations for 2021.

Turning to Slide 3. Our strategic priorities guide all that we do as we work to transform our company. Being a force for good and creating sustainable value that benefits all of our stakeholders is one of our three priorities and is the foundation around which our environmental, social and governance strategy is built. Earlier this week, we published our 2020 Corporate Responsibility Report, which serves as an annual accounting of our performance and our progress to adapt more sustainable practices to help people live their best life. While we are early in our ESG journey and have much to do on this front, I'm pleased with our progress to date as reflected in our latest report.

Moving to Slide 4. This is a snapshot of our segment and consolidated revenues, and our adjusted EBITDA for the quarter. First quarter revenues of $718 million decreased 12% compared to prior year. This revenue decrease was primarily due to anticipated lower Generic Pharmaceuticals and Sterile Injectable segment revenue. Reported first quarter adjusted EBITDA of $365 million decreased by 13% compared to prior year. This decrease was primarily due to lower consolidated revenues coupled with higher adjusted operating expenses, reflecting our investment in the launch of Qwo and our continued strong commercial investment in XIAFLEX. First quarter 2021 consolidated revenues and adjusted EBITDA exceeded our previously communicated expectations due to better-than-expected performance in certain key products across our segments, higher adjusted gross margin partly due to favorable product mix and lower adjusted operating expenses mainly due to phasing.

Turning to Slide 5. Our Branded segment first quarter revenues increased compared to the prior year, driven by specialty products portfolio revenue growth of 7%. XIAFLEX revenues increased by 7% in the first quarter compared to prior year, driven by strong demand growth for both XIAFLEX indications, partially offset by channel inventory destocking that occurred in the first quarter of 2021 compared to prior year. As we discussed earlier this year, we're investing in the XIAFLEX commercial strategy that includes increasing patient awareness through expanded promotion to empower patients to seek nonsurgical options coupled with physician education and training. We're encouraged by the strong patient interest to seek treatment, which is fueling underlying demand across both indications as measured by consumer traffic to our website and physician locator sites. This is a good early indicator of patient interest and initial consumer activation.

Patient office visits for elective procedures in the first quarter continued to be below pre-COVID levels and we're fairly in line with our expectations. We're encouraged by the increasing levels of vaccinations nationally and expect patient office visits for elective procedures to steadily increase over the remainder of the year. Based on this, we continue to expect utilization of our physician-administered products such as XIAFLEX to be weighted toward the second half of the year.

Revenues from our Established Products portfolio declined by 9% compared to the same period in the prior year, primarily due to ongoing competitive pressures. Revenues from our Sterile Injectables segment declined by 8% compared to the first quarter of 2020. VASOSTRICT revenue growth of 10% in the quarter was more than offset by the decrease in revenue for certain products, such as adrenaline and ertapenem due to the impact of generic competition. VASOSTRICT first quarter utilization, specifically in the month of March, was higher than we expected. However, as we look forward, we expect that VASOSTRICT volumes to begin to decreased toward pre-COVID-19 levels during the second quarter of 2021, as COVID-19-related hospitalizations continue to decline.

Moving to Slide 6. Revenues from our Generic segment decreased by 20% in the first quarter compared to the prior year. The decrease was primarily due to the impact of anticipated competitive pressures on certain key products, coupled with accelerated prescription fulfillment related to the COVID-19 that occurred in the first quarter of 2020. This decline was partially offset by the successful launch of lubiprostone capsules, the authorized generic for Amitiza, in January of this year.

Generic segments first quarter revenues exceeded our expectations primarily due to higher-than-expected lubiprostone launch performance, coupled with the delayed impact of anticipated generic competition on certain products. Finally, the expected decrease in International segment revenues for the first quarter was primarily due to ongoing generic competition.

Turning to Slide 7. We are excited by our entry into the Medical Aesthetics with the launch of Qwo in March. Qwo is the first and only injectable approved for the treatment of cellulite, and provides a nonsurgical option that addresses the underlying cause of cellulite. We believe Qwo's unique profile provides the Medical Aesthetics practitioners an opportunity to create a new vertical and grow their business. We launched Qwo through an early experience program that targeted select practices. The program focused on product education, patient selection, managing patient expectations, and building practice success.

As we discussed earlier this year, we are taking a deliberate and progressive approach to our launch of Qwo, and the process we are undertaking for activating in on boarding accounts. During the month of April, after the successful rollout of our early experience program, we began the process of onboarding additional accounts. Activated accounts are being supported with a strong injector training program, delivered both virtually and in person. Ongoing education will continue to be important and will be delivered through virtual educational webinars and peer-to-peer programing. We also recognized the need to equip practices with the tools they need to support practice integration activation. To accomplish this goal, we have launched our Qwo health professional course. Additionally, we announced our launch pricing and believe the price point represents a strong value proposition for practices and consumers who are seeking treatment.

To date, we have received positive feedback on Qwo from the Medical Aesthetic community. Activated practices have generated strong buzz by announcing availability of Qwo and posting their own before and after pictures on social media. Additionally, consumer and trade, media interest and excitement remains strong, with more than 300,000 unique visitors to the Really Cellulite webpage, and greater than 5.3 billion media impressions in the first quarter, including top tier print and broadcast outlets. While only about one month post launch, we are on target with our planned account on boarding, purchase and utilization rates. As we progress, we will share more information as it becomes more meaningful.

Moving to Slide 8 and discussing our ongoing Branded segment clinical studies and pipeline. Starting with Qwo. Our data generation plan and development remains focused on dosing, injection technique and responses in target patient populations, as well as rollover studies on durability. For example, our 305 Phase IIIb real study looked at Qwo effectiveness in a real world population as well as thigh injection technique and overall investigator experience. At day 90, investigator perceived improvement scores were greater than 90% in cellulite appearance and 90% of investigators agreed or strongly agreed to incorporate Qwo into their practice.

Results and analysis from these studies are key to our publication and presentation strategies. We continue to make progress on XIAFLEX development programs. Starting with the treatment of plantar fibromatosis, we are looking forward to the date of publication of our proof of concept study results in the coming months. We plan to progress our plantar our fibromatosis program with the initiation of a Phase II study in the second half of this year. In terms of adhesive capsulitis, our Phase IIb study interim analysis is anticipated toward the end of the year. We believe both plantar fibromatosis and adhesive capsulitis represent an opportunity to bring innovative treatment option to address a potential large unmet need for patients who are seeking a nonsurgical approach to treatment.

Turning to Slide 9. We continue to evolve our R&D pipeline and manufacturing capabilities to support the introduction of more sterile products, focusing on the evolving needs of our customers. And with 80% of R&D pipeline consists of projects across the Sterile Injectable product continuum, with approximately two thirds in ready to use and other more differentiated products. Across our Sterile Injectables and Generic segments, we plan to launch approximately 10 products in 2021, which includes the successful launch of lubiprostone capsules, the authorized generic of Amitiza, in the first quarter of this year.

Now let me turn the call over to Mark to further discuss the company's financial results and our financial guidance. Mark?

Mark Bradley -- Executive Vice President and Chief Financial Officer

Thank you, Blaise, and good morning, everyone. First, on Slide 10 you will see a snapshot of our first quarter GAAP and non-GAAP financial results Blaise covered company and segment revenues earlier, so I will not review that again. On a GAAP basis, income from continuing operations was approximately $47 million or $0.20 per share on a diluted basis in the first quarter of 2021 compared to income from continuing operations of approximately $158 million or $0.68 per share on a diluted basis in the first quarter of 2020. This decrease was primarily attributable to a discrete tax benefit arising from the CARES Act that was recorded for GAAP purposes in the first quarter of 2020, but not in the first quarter of 2021.

On an adjusted basis, income from continuing operations was $175 million or $0.73 per share on a diluted basis in the first quarter of 2021 compared to income from continuing operations of $220 million or $0.95 per share on a diluted basis in the first quarter of 2020. This decrease was primarily due to lower revenues and higher adjusted operating expenses in the first quarter of 2021 compared to the prior year.

Turning to Slide 11. Based on better-than-expected performance across all of our segments in the first quarter, we are raising the low end of our 2021 full year financial guidance. We now expect full year 2021 total revenues to be between $2.65 billion dollars and $2.79 billion dollars, adjusted EBITDA to be between $1.18 billion and $1.28 billion, and adjusted diluted net income per share from continuing operations to be between $1.95 and $2.30.

Our full year 2021 guidance continues to assume an adjusted gross margin of approximately 70% to 71%. However, we updated our adjusted operating expenses as a percentage of revenue assumption to be between approximately 28.5% and 29%. Additionally, we now assume adjusted interest expense will be approximately $560 million, which reflects the impact of the recently completed debt refinancing. With respect to quarterly phasing, we expect total revenues to decline between approximately $30 million and $70 million in the second quarter of 2021 compared to the first quarter of 2021. This decline is expected to be driven by anticipated lower Sterile Injectable segment revenues due to expected lower VASOSTRICT revenues as demand begins to return to more normalized levels.

Second quarter Generic Pharmaceutical segment revenues are also anticipated to be lower due to expected lower lubiprostone revenue following the launch load that occurred in the first quarter, coupled with expected competition on other generic products. These declines are anticipated to be partially offset by an increase in Branded Pharmaceutical segment revenues, primarily due to the continued expected growth in XIAFLEX in the second quarter. Additionally, we expect adjusted gross margin in the second quarter to be slightly lower than the low end of the full year 2021 guidance range, reflecting the change in product mix. Finally, we expect the total dollar amount of operating expenses and the adjusted effective tax rate in the second quarter to remain relatively flat compared to the first quarter of 2021.

Switching to Slide 12. This is a summary of full year segment and total enterprise revenue assumptions. As you will notice, we have slightly updated the full year revenue assumptions for our Sterile Injectables and Generic Pharmaceutical segments.

Advancing to Slide 13 and wrapping up the financial discussion, unrestricted cash flow prior to debt payments was $250 million in the first quarter of 2021 compared to $86 million in the prior year. This increase was primarily due to an increase in cash flow from the change in net working capital and a decrease in distributions to settle mesh claims.

We ended the first quarter of 2021 with approximately $1.4 billion of unrestricted cash and a net debt to adjusted EBITDA leverage ratio of approximately 5.1 times. For the full year 2021, we are updating our expectations for unrestricted cash flow prior to debt payments to be between approximately $140 million and $240 million, compared to our prior estimate of between $80 million and $240 million. This change reflects the increase in the low end of the adjusted EBITDA guidance range previously discussed.

Let me now turn the call back over to Blaise. Blaise?

Blaise Coleman -- President and Chief Executive Officer

Thank you, Mark. Prior to turning the call over to Laurie to manage our question-and-answer period, I understand there are many questions on the recent developments as it pertains to the ongoing opioid litigation, including the recent default order on liability in Tennessee and the ongoing trial in California. However, as I'm sure you can appreciate, we are limited in what we can say. What I will say with respect to Tennessee, is first, to reiterate our prior statement that we strongly disagree with the court's default order on liability. I'd also like to clarify that despite certain press reports that there has been no finding to date that Endo's owes any amount as a result of the default order. Instead, a damages trial was currently scheduled to begin on July 26. That said, we did recently file a notice of appeal with respect to the default order, and we are seeking a stay on the damages trial pending the outcome of that appeal.

With respect to California, we're in the midst of the liability phase of that trial, so I'm not going to comment on that ongoing proceeding. With respect to the opioid litigations on hold, we continue to be open to identifying and executing on a constructive path for resolution. And it's important to note that while constructive resolution remains our goal, there can be no assurances that this will be achieved and we are prepared to continue to litigate if necessary. More importantly, while our legal team is focused on litigation, the rest of the Endo team is highly focused on our day-to-day business execution, advancing our strategic priorities and delivering our portfolio of life-enhancing products to our customers and the patients they serve.

Laure, let's please move now to the question-and-answer period.

Questions and Answers:

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thank you, Blaise. In the interest of time, if you could limit your initial questions to allow us to get in as many as possible, we would appreciate it. Operator, can we have our first question please.

Operator

Your first question comes from the line of Chris Schott with J.P. Morgan. Your line is open.

Katrina -- J.P. Morgan -- Analyst

This is Katrina [Phonetic] on for Chris. Thank you so much for taking the questions. I guess the first one is, there's been some mixed data points on the generics environment recently, so just your thoughts on this and any changes that you're seeing in that market in terms of pricing or overall competitive environment?

The second question is on VASOSTRICT. As we think about moving, in fact that COVID admissions [Phonetic] had volumes and the normalization of that product as we move through the year. Is there any stickiness and all to that higher utilization that we've seen through the epidemic that you think can persist as we move kind of in 2022, 2023? Or it just a matter of how steep the ramp down within the product in terms to pre-COVID-19 levels? Thank you.

Blaise Coleman -- President and Chief Executive Officer

Great, thank you very much for those questions. So first on the generics piece. For us right now when we think about the generics portfolio, we've been very clear that we are seeing a fair amount of competition impact to our outlook for 2021, has to do with competitive events that occurred in '20 and some events are going to happen in '21. So our outlook there for our portfolio is a challenging one for '21 because of those competitive events.

On the VASOSTRICT point, as we noted, we are planning for VASOSTRICT levels to return to pre-COVID-19 levels, really starting in the beginning in the second quarter of this year and then sort of as we move through the rest of the year. There isn't -- we at this point, when we think about our range, we are considering the possibility that there may be some additional elevated levels of VASOSTRICT above that level, and that's considered in the range. But as of now, our going-in assumption is that we're going to see VASOSTRICT levels return more back to that pre-COVID-19 levels as we move into the second half.

Katrina -- J.P. Morgan -- Analyst

Thank you.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Next question please.

Your next question comes from the line of Greg Gilbert with Truist Securities. Your line is open.

Greg Gilbert -- Truist Securities -- Analyst

Thanks, good morning. First one is on Qwo. I know the company has done -- has been very proactive in setting expectations on bruising and tolerability. But how would you characterize the real world feedback so far? On frozen shoulder, you mentioned an interim look. Should we view that as sort of a go-no-go decision? Or how would you frame the interim look in the potential sort of outcomes of that since it's a this year event? And lastly Blaise, when you think about your Sterile Injectables line, excluding vaso, and maybe we can lump generics into this too. Conceptually, over the years, do you see a business that can can be flattish with the pipeline offsetting natural erosion? Do you expect growth, again more conceptual over time, I realize you're not going to guide, but wanting to understand your expectations there based on what you've built so far? Thanks.

Blaise Coleman -- President and Chief Executive Officer

Yeah, Greg. Thank you very much for those questions. On the Qwo piece, I'll ask Patrick to give you some feedback. I mean, obviously, the market receptivity on Qwo to date. We've been really excited about, but in a minute turn it over to Patrick on the Qwo piece. On the XIAFLEX piece, in terms of adhesive capsulitis and frozen shoulder. Yeah, we have an interim data point coming up at the end of the year and it's like any other data point. There is the possibility that that could be a go-no-go decision based on what we see in that interim data, but we'll have to see what that looks like.

And then from a Sterile Injectable standpoint, again, you're right Creg, we're not going to guide on that and there is a lot of variables at play in terms of what the durability of VASOSTRICT looks like over time. But as you know, we are hyper focused on continuing to transform our Sterile Injectable portfolio to what I would call probably less absolute number of projects in Sterile Injectables, but what we consider to be more high value injectable opportunities as we think about the transformation we're trying to make in terms of moving up that product continuum to more what we would consider differentiated opportunities. So maybe with that, I'll turn it over to Patrick to give you some feedback on not just your specific question, but overall how we're seeing the market react to our Qwo to date.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Thanks for the question, Greg. As you cited, it is certainly early days, but we're very pleased and encouraged by the receptivity in the marketplace. I would point to a couple of things in terms of positive momentum. We launched with an early experience program, where we're focused on about 350 to 360 of the top market influencers, key investigators. We gave some early access to Qwo. We had over a 90% participation rate post registration. Really terrific if you consider this was their free time, a Friday night, a Saturday, so that they can learn about Qwo and have early access to it, and that generated a tremendous amount of social media buzz and a lot of, I think a positive uptake in the market relative to social media streams.

We mentioned on the call a really strong pick up on our Really Cellulite Campaign with over 105 million impressions to date, and a really, really high completion rate. In terms of how the product is performing in the marketplace, the other thing I would note is the receptivity to our price. We did launch coming out of the early experience program. We launched our introductory price to great fanfare and the feedback generally has been, hey you guys got it right. This creates an opportunity for them to create a new vertical, grab good margin, yet have a price that's very, very accessible to their consumer, so we were pleased with that.

And specifically to your questions. One of the things that's really important to us is to set proper expectations in the marketplace. And so, as we go to deeply integrate in each and every account, it's all about patient selection. It's not running from adverse events, it's really setting an expectation for the injectors as to what to expect, how to manage that. Bruising is one of those things, that was one of the more prominent AEs in our Phase 3 pivotal trials. I would note that it's not necessarily a deep bruising associated with a great deal of pain. So it's -- what we've heard from clinicians is that it's been very manageable. They've appreciated how we've gotten up front of this and allowing them to properly set expectations with their patients and so far. The other thing that's important is that the products behaving well and performing well in real life patients. So we're really pleased with what's happening.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thank you, Greg. Next question please.

Next question is from David Amsellem with Piper Sandler. Your line is open.

David Amsellem -- Piper Sandler -- Analyst

Thanks. On VASOSTRICT, with the trial, I wanted to get your latest thoughts on your openness to settlement with Eagle, particularly in the context of Eagle struggling with its filing it's complete response letter and the fact that it had to do another trial. So how does that impact your strategic calculus regarding a settlement there? Just your latest thoughts there.

And then on Qwo, was it adjusted and when we may get duration of effect that I noticed in the slide you had that laid out the five-year extension when we might start to see that, and what's the perception around duration of effect in the marketplace? Thanks.

Blaise Coleman -- President and Chief Executive Officer

Great. Thanks, David. And I'll turn over in a minute for Patrick to help on the Qwo question. On VASOSTRICT, David let me just say where we're at. So just for everyone's benefit, we are -- we continue to be scheduled to have a trial in Delaware in July and we are well prepared for that trial. We do continue to remain open to the opportunity to resolve this matter through a constructive settlement. That's been our position from the beginning. It continues to be our position. And that's where things really stand right now on the VASOSTRICT matters. So maybe I'll turn it over to Patrick to comment a little bit around our durability study aspect of things.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Thanks for the question, David. As you know, our label is silent on durability. But what I would say is we do have very positive durability data that's emerging from our -- even going back to our Phase IIb rollover and our Phase III has a rollover designs. So we do have positive durability data right now as we speak that goes out to over 720 days in some patients. So that's something as that data becomes available -- that data generation becomes available, it'll begin to be discussed at podium. We obviously have to consider our publication strategy behind that. And then that becomes a strategic question over time in terms of what we might want to introduce in terms of a label update. So for now, it's somewhat open-ended with some really, really strong positive durability data emerging. I mean, it scientifically hypothetically. Clinicians tell us that once that fibrous septae is lysed, its lysed. So hypothetically, it makes sense that we're seeing this type of durability in real world patients.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thank you, David. Next question please.

Operator

Its from Navann Ty with Citi. Your line is open.

Navann Ty -- Citibank -- Analyst

Hi, good morning. Thanks for taking my question. On the opioids, I understand you're limited in what you can say. But can you describe the next, maybe days we should look out for? And how confident is your legal team about the appeal in Tennessee? And then I have a second question on Qwo. If you could let us know early feedback regarding pricing and the next step after the early experience program? Thank you.

Blaise Coleman -- President and Chief Executive Officer

Great, thank you for the Qwo. So I'll first let Patrick take the question on pricing as well as the next steps that we've already taken post dealer experience program on Qwo, and then we'll come back to the opioid question.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Yeah, let me start with price and I touched on it earlier. I would say that in general the feedback from our customers is that you've got it right, that was probably one of the more important strategic decisions that we made. And as we've said, for the last year, we wanted to introduce a price that created a good opportunity for a new vertical for customers, but wide scale adoption for consumers as well. And we feel like we hit the mark with an introductory price of $200 for the 4 mL and $350 for the 8 mL. Ideally, what that does is that allows physicians to address all patients that they would have who would be bothered by cellulite in seeking treatment. So we're very pleased by that because we think over time that will establish a very -- will establish a very accessible price point, and we've already articulated for the last year that we see this is as a big opportunity in a big market.

In terms of what's next, we're going to continue to take a very progressive and focused approach to targeting on boarding of our accounts. So we want to again continue to talk about with our accounts, ensuring proper patient selection, a lot of focus on injector training over the shoulder and virtual to make sure that injection technique is understood, and then we're going to focus on building and expanding to a broader market over time. What we are doing this year is some strong digital and social consumer activation, which is very targeted. We're leveraging paid search social digital. And then as we get later into the year after we have an established base of accounts, we'll continue to evaluate our focus -- more focus direct to consumer rollout, leveraging geo-fencing [Phonetic] and geo targeting and targeted DMAs, where we know we have critical massive injectors because we recognize over time as this brand grows, there is that consumer activation opportunity for us, and so we view it as a category creating opportunity for us that will require us to activate the market through creating brand awareness with consumers.

Blaise Coleman -- President and Chief Executive Officer

And then on your question on Tennessee. As we said in the prepared remarks, we reiterate our comments that we strongly disagree with the default judgment in the Tennessee matter and we have submitted briefings and filed notices of appeal, where we are seeking a stay of the damages trial pending the outcome of that appeal, and the damages trial was currently scheduled for July 26 in terms of the timing.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Your next question is from Daniel Busby with RBC Capital Markets. Your line is open.

Daniel Busby -- RBC Capital Markets -- Analyst

Hey, good morning, everyone. Two questions. First a follow-up on Qwo. You used the term introductory price, should we take that to mean you intend to adjust price going forward as you move further to launch? And second, given the strong first quarter performance relative to your own first quarter guidance, can you talk a little bit more about why full year guidance wasn't raised further? Thank you.

Blaise Coleman -- President and Chief Executive Officer

Yeah, why don't I turn the pricing question over to Patrick and I'll let Mark handle the question on guidance.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Yeah, thanks Blaise for the question. Again, we did launch an introductory price, wanted to make it simple, understandable in terms of how to really integrate Qwo into their practice. We have not made any comment as of yet in terms of how long that introductory price will run. So that's a bit of an open-ended question for us for now that at the right time we will be commenting further. But for now, we're -- again we're going to stick with the introductory price.

Mark Bradley -- Executive Vice President and Chief Financial Officer

Yeah, so with respect to the question on full year guidance. So I think, one thing we need to think about is first quarter and what impacted first quarter. And there's a couple of things that we mentioned in our prepared remarks, the first of which was elevated VASOSTRICT utilization, particularly in January and February, which as Blaise mentioned. We expect to see VASOSTRICT utilization decline over time and return to pre-COVID levels as soon as the second quarter here. We also saw lubiprostone launch load, which is kind of one-time in nature. And then, we also saw operating expenses come in at the lower end of our range. As we go forward through the year, we expect to see increased demand for our physician administered products, specifically XIAFLEX, so that will provide a tailwind into the remainder of the year. And we also expect to see offsetting that higher generic competition in the back half of the year that we didn't see was kind of delayed from our expectations. And then finally, operating expenses. Again, we saw a little bit of favorability in the first quarter and that's really just due to phasing. We expect to see higher operating expenses at the end of year. When you take all of those things into consideration, that's why we were able to adjust the lower end of our guidance range.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thanks. Excellent, Mark. Next question please.

Your next question is from Gary Nachman with BMO Capital Markets. Your line is open.

Gary Nachman -- BMO Capital Markets -- Analyst

Hi, thanks, good morning. First on Generic. How much did lubiprostone actually contribute in the quarter? Next, on the other Sterile Injectables that dropped off a fair amount. What happened with adrenaline and ertapenem in terms of competitive dynamics since those products have been a lot stickier in the past? And then just lastly on Qwo. Are patients coming back to get follow-up injections or is it too early to know yet? I'm curious if you'd seen that yet since you did launch it back in March. Thank you.

Blaise Coleman -- President and Chief Executive Officer

Great, thank you, Gary for those questions. Yeah, Gary, we're not disclosing the lubiprostone sales contribution. But as we said, we saw better performance there. And really the better performance came from, quite frankly a faster conversion of the generic than we had anticipated, which is a much quicker conversion curve. On the other and Sterile Injectable question, what have -- there is two components to that. So one is, and I'm defining others Sterile Injectables as presented in our press release. There's two components to why we saw the change that we did. One is, there was a destocking component. And then two, there were some competitive events and there's a number of products that are in that basket, including ertapenem that were impacted.

In terms of adrenaline, I think if you look from Q4 to Q1, our adrenaline sales were relatively flat. And what you're seeing from Q1 of last year to Q1 of this year is really the impact from the entry of adrenaline competition in the first half of last year, in the second quarter actually of 2020. And then I'll turn it over to Patrick for your question on Qwo.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Thanks for the question. Obviously, it's real early, we're essentially only a month and so we wouldn't anticipate that we're seeing patients come back in when they're still arguably going through a full correction on the first course of therapy. But as it relates to retreatment, that is something that we look at as a potential upside. Hypothetically, we could see over time patients coming back for touch-ups or perhaps based on a good patient experience migrating to other targeted areas. And so as we think about the outlook over time, that could potentially create some positive momentum for us in terms of retreatment.

Laure Park -- Senior Vice President of Investor Relations and Corporate Affairs

Thanks. The next question please.

Your next question is from Annabel Samimy with Stifel. Your line is open.

Annabel Samimy -- Stifel -- Analyst

Hi, thanks for taking my question. I was wondering on Qwo. Just going forward, are you going to be sharing any specific metrics for us in terms of accounts that you've penetrated? What your target account numbers are as well as metrics for Qwo [Phonetic] injections? Anything that we can sort of start wrapping our head around. And then in terms of some of the feedback that you're receiving, not just on the product performance but on anecdotal demand, you mentioned 105 million social impressions, but what are some of your target or some of your early adopters saying in terms of the demand that they're receiving from their patients? So anything that you can give us to help us translate 105 million impressions into an actual patient. Thanks.

Blaise Coleman -- President and Chief Executive Officer

Yeah, Annabel, thank you very much. Your first question around metrics. Yeah, as over time, we will be coming and sharing more information around what we consider to be the key performance indicators as they become more meaningful. And then in terms of the question around overall market receptivity and some of the feedback we're receiving maybe more qualitatively, I'll let Patrick provide some more color on that.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Yeah, I appreciate your question. And again, as Blaise said., as we look at number of accounts on board than we look at how the brand is performing in the form of reorder rates, those are things we will be obviously be looking at. I mean, keep in mind for the month of March, we launched with early experience program and were really literally less than one month in on launch. So in terms of our ability to on-board accounts, we're really establishing those initial orders. And as I talked about, it's important to integrate this deeply into their practice. It's an injectable. It's simple to operationalize. But this is new, this is new. Obviously, physicians have lots of experience with Injectables, some have experience with body contouring and Injectables. But this is a brand new vertical, so it's important that we go deep into each and every account. We really drive toward get outcomes on making sure their entire staff understands patient selection, how to manage adverse events, that we really help them prop up their marketing plan in terms of how to drive consumer activation within their practice. Certainly, we're going to be doing activities in the market ourselves to support that. But again, we're about 3.5 weeks in. I would say that as we approach accounts -- our targeted accounts in terms of initiating initial stocking order for them to get the product in, that we've been very encouraged by the receptivity of accounts willing to bring it in. And then once the product is brought in, our Aesthetic business managers go to work in terms of putting together an integrated plan to pull that through and to drive patient demand within each of the clinics.

Next question is from Balaji Prasad with Barclays. Your line is open.

Balaji Prasad -- Barclays -- Analyst

Hi, good morning, and thanks for getting me back on. So two questions from my side. One on Sterile Injectables. Could you maybe give broadly the nature of the products that you're planning to launch in 2021? And also kind of juxtapose this with current shortages on the injectable side, and any broad observations that can you can draw on the pricing for Sterile Injectables?

Secondly on Qwo. I would be interested to get your insights into how you think the use is likely to evolve? Our export conversations kind of lead us to believe that Qwo would be ideal in combination with fat reduction and our body contouring procedures, I think you just called out previously. And commercial potential or expansion of commercial potential if such a use evolves? Thank you.

Blaise Coleman -- President and Chief Executive Officer

Thanks, Balaji. Thanks for those questions. On the Sterile Injectable front, we are -- in terms of the launches we have planned for 2021, we're not going to comment on anything specifically, but we will have a combination of products that would be more traditional pay rate [Phonetic] of vials, but also introducing some products that are more ready to use, starting to reflect that transition we're making from an overall portfolio perspective.

In terms of just general commentary you've asked for, I think on the Sterile Injectable and pricing trends. Again, depending on what product we're speaking to and what the pricing trend is for that product really has to do with the competitive landscape. And so we are -- when we think about the more traditional pay rate of vials, we are seeing on certain products increased competition which is somewhat normal. And then as we move forward, again our focus is going to be on what we consider to be more differentiated products, where we think there will be a bit more of durability and pricing power in the market going forward. And then I'll let Patrick comment for you on the Qwo question and how the use of that may or may not evolve over time.

Patrick Barry -- Executive Vice President and President, Global Commercial Operations

Yeah, thank you for the question. As you say based on your work with actual clinicians, we know that cellulite is multi-factor -- its multifactorial. There is an element of dermal quality, skin laxity, there is some fat. There is a fat component there. There is also the underlying cause of cellulite, which is the Fibrous septae. And so when we look at the mechanism, we believe the mechanism of Qwo to really address enzymatically lysings of that Fibrous septae. We also have some interesting data that is suggesting that maybe even close mechanism might be multifactorial as well. But certainly as an injectable that addresses the underlying cause of cellulite, being the fibrous septae, we believe that Qwo can be a cornerstone treatment for the treatment of cellulite. And again, a new category for them. So it's really about getting it in the hands of accounts, getting it in the real world, having them inject. As an injectable, we feel like it could be the central product. And certainly as you say, we have heard doctors are interested in trying to figure out what else to wrap around Qwo, and certainly that presents opportunities for them to put packages together so that they can effectively treat cellulite. But we do believe operationally that as an injectable, Qwo can be a cornerstone treatment for cellulite and we think physicians will adopt it in that way.
