The current regulatory status of Mounjaro for sleep apnea

As of April 2026, Mounjaro (tirzepatide) is FDA-approved for two indications: type 2 diabetes (approved May 2022) and chronic weight management under the brand name Zepbound (approved November 2023). It is not yet approved for obstructive sleep apnea.

Eli Lilly submitted a supplemental New Drug Application (sNDA) to the FDA on August 9, 2024, requesting approval for tirzepatide as a treatment for moderate-to-severe obstructive sleep apnea in adults with obesity. The submission was based on results from two Phase 3 trials collectively called SURMOUNT-OSA.

The FDA accepted the application for review in September 2024 and assigned a Prescription Drug User Fee Act (PDUFA) target action date of August 15, 2026. This is the date by which the FDA commits to completing its review and issuing an approval, complete response letter (requesting more data), or rejection.

The agency granted Priority Review status, which shortens the standard 10-month review timeline to 6 months, but Eli Lilly's submission came with manufacturing site inspections and additional post-marketing study commitments that extended the timeline back toward the standard window.

Three things can happen between now and August 2026:

1. The FDA approves tirzepatide for OSA on or before the PDUFA date (most likely scenario based on trial strength).
2. The FDA issues a complete response letter asking for additional data, delaying approval by 6 to 18 months.
3. The FDA rejects the application outright (highly unlikely given the trial design and effect size).

Industry analysts place approval probability at 85% to 92% based on the trial's primary endpoint success and the unmet medical need in OSA treatment (Evaluate Pharma, 2025).

What the SURMOUNT-OSA trial actually demonstrated

SURMOUNT-OSA was not a single trial but two parallel randomized, double-blind, placebo-controlled Phase 3 studies enrolling a combined 469 adults with obesity (BMI 30 or higher) and moderate-to-severe obstructive sleep apnea.

Trial 1 enrolled patients not using positive airway pressure (PAP) therapy. Trial 2 enrolled patients who were using and planned to continue CPAP or BiPAP.

Both trials randomized patients 1:1 to either tirzepatide (dose-escalated to 10 mg or 15 mg weekly) or placebo for 52 weeks.

The primary endpoint was change in apnea-hypopnea index (AHI), the standard measure of OSA severity. AHI counts the number of breathing pauses (apneas) and shallow breaths (hypopneas) per hour of sleep. An AHI of 5 to 15 is mild OSA, 15 to 30 is moderate, and over 30 is severe.

Results from Trial 1 (no PAP therapy): Patients on tirzepatide 15 mg experienced a mean AHI reduction of 27.4 events per hour compared to 4.8 events per hour on placebo. Baseline AHI averaged 49.5 events per hour (severe OSA). The between-group difference was 22.6 events per hour, statistically significant at p < 0.0001 (Malhotra et al., NEJM 2024).

This represents a 55% reduction in AHI from baseline in the tirzepatide group.

Results from Trial 2 (continued PAP therapy): Patients on tirzepatide 15 mg saw a mean AHI reduction of 29.3 events per hour compared to 5.3 events per hour on placebo. Baseline AHI averaged 51.5 events per hour. The between-group difference was 24.0 events per hour, p < 0.0001.

Secondary endpoints included change in body weight (tirzepatide patients lost an average of 18.1% to 20.1% of body weight vs 1.3% to 2.3% on placebo), patient-reported sleep quality (measured by Functional Outcomes of Sleep Questionnaire), and hypoxic burden (cumulative time spent with oxygen saturation below 90%).

The hypoxic burden reduction was clinically meaningful. Patients on tirzepatide spent 43% less time with oxygen desaturation compared to 12% reduction on placebo. This matters because nocturnal hypoxemia drives cardiovascular risk in OSA, independent of AHI (Azarbarzin et al., Am J Respir Crit Care Med 2019).

Adverse events were consistent with tirzepatide's known profile: nausea (31% vs 9% placebo), diarrhea (24% vs 7%), and constipation (17% vs 6%). Discontinuation due to adverse events occurred in 7.6% of tirzepatide patients vs 2.1% of placebo patients.

The trial did not demonstrate non-inferiority to CPAP. It demonstrated superiority to placebo and additive benefit when combined with CPAP. This distinction will shape how the indication is worded.

The three-phase FDA review timeline (where we are now)

The FDA's review of a supplemental NDA follows a structured process.

Phase 1: Filing and planning (complete). The FDA has 60 days from submission to decide whether to accept the application for review. Eli Lilly's submission was accepted in September 2024. The agency confirmed the application was sufficiently complete to permit substantive review.

Phase 2: Primary review (currently underway, April 2026). The FDA's Division of Metabolism and Endocrinology Products is conducting a detailed review of the clinical trial data, manufacturing processes, labeling language, and risk-benefit profile. This phase includes:

• Biostatistics review of the trial's primary and secondary endpoints
• Clinical review of safety data across the 469-patient trial population
• Inspection of Eli Lilly's manufacturing facilities (completed February 2026)
• Review of proposed labeling language, particularly how the indication will be worded

The FDA may convene an advisory committee meeting to discuss the application, though this is not required for a supplemental indication when the drug is already approved. As of April 2026, no advisory committee meeting has been scheduled, which suggests the agency views the data as straightforward.

Phase 3: Final decision (expected July to September 2026). The FDA will issue one of three decisions by the August 15 PDUFA date:

1. Approval with labeling as submitted or with minor modifications
2. Complete response letter requesting additional data (most commonly, longer-term safety data or specific subgroup analyses)
3. Rejection (rare for a supplemental indication with positive Phase 3 data)

If approved, the indication will likely read: "Mounjaro is indicated as an adjunct to diet and increased physical activity for the treatment of moderate-to-severe obstructive sleep apnea in adults with obesity."

The word "adjunct" is critical. It signals that tirzepatide is not a replacement for CPAP in patients who tolerate it, but an addition to standard care.

Why sleep apnea approval matters differently than diabetes or obesity approval

The diabetes and obesity approvals for tirzepatide were relatively straightforward from a payer perspective. Diabetes has clear diagnostic criteria (HbA1c, fasting glucose) and established treatment algorithms. Obesity has BMI thresholds.

Sleep apnea approval introduces three new complexities that will shape real-world access.

Complexity 1: Diagnosis requires a sleep study. You cannot diagnose obstructive sleep apnea from symptoms alone. Insurance companies will require documented AHI from either an in-lab polysomnography or a home sleep apnea test. This adds a diagnostic step (and cost) before treatment eligibility.

Patients who suspect they have sleep apnea but have never been formally tested will need to complete a sleep study before Mounjaro for OSA becomes a covered option.

Complexity 2: CPAP is still first-line therapy. The American Academy of Sleep Medicine's clinical practice guidelines (updated 2024) recommend positive airway pressure as first-line treatment for moderate-to-severe OSA. Mounjaro will be positioned as second-line or adjunctive therapy.

Most insurance plans will require documentation of CPAP trial and either failure (AHI remains elevated despite adherent use) or intolerance (patient cannot tolerate the device). This is the same prior authorization hurdle that exists for oral appliances and hypoglossal nerve stimulation.

Complexity 3: The indication will likely require obesity. The SURMOUNT-OSA trials enrolled only patients with BMI 30 or higher. The FDA approval will almost certainly restrict the indication to adults with obesity, excluding the roughly 30% of OSA patients who are not obese.

This means a patient with severe OSA and a BMI of 28 cannot access Mounjaro under the sleep apnea indication, even if their provider believes it would help. They would need to qualify under a different indication (diabetes, if present) or pay out of pocket.

What most articles get wrong about the sleep apnea indication

Most coverage of the SURMOUNT-OSA trials emphasizes the 55% AHI reduction and frames tirzepatide as a "CPAP alternative." This is misleading in three specific ways.

Error 1: Conflating AHI reduction with cure. A 55% reduction in AHI is clinically significant, but it does not mean OSA is resolved. In Trial 1, the mean baseline AHI was 49.5 events per hour (severe OSA). After 52 weeks on tirzepatide 15 mg, the mean AHI was 22.1 events per hour, still in the moderate OSA range.

Only 42% of tirzepatide patients achieved an AHI below 15 (the threshold for mild OSA) compared to 12% of placebo patients. This is a meaningful improvement, but most patients still had residual OSA requiring monitoring (Malhotra et al., NEJM 2024).

CPAP, by contrast, can reduce AHI to near zero in adherent users. Tirzepatide reduces OSA severity but does not eliminate it in most patients.

Error 2: Ignoring the weight-loss mechanism. Tirzepatide does not treat sleep apnea through a direct airway effect. It treats sleep apnea by reducing the fat deposition around the upper airway, reducing tongue volume, and decreasing the mechanical load on the chest wall during sleep.

This means the AHI benefit is proportional to weight loss. Patients who lose 25% of their body weight see larger AHI reductions than patients who lose 10%. Patients who regain weight after stopping tirzepatide will see AHI return toward baseline.

This is fundamentally different from CPAP, which provides immediate mechanical support regardless of weight.

Error 3: Assuming immediate insurance coverage post-approval. FDA approval does not guarantee insurance coverage. Payers write their own medical policies. Many commercial plans took 12 to 18 months after Zepbound's obesity approval to add it to formularies, and even then, most placed it on specialty tiers with high copays and strict prior authorization.

The sleep apnea indication will face the same lag. Expect 6 to 12 months post-approval before most major payers update their policies to cover Mounjaro for OSA, and expect those policies to require sleep study documentation, CPAP trial, and obesity diagnosis.

Insurance coverage predictions: the CPAP-failure requirement

Based on how payers currently cover other second-line OSA treatments (oral appliances, Inspire hypoglossal nerve stimulator), we can predict the prior authorization criteria for Mounjaro post-approval.

Predicted PA requirements:

1. Documented moderate-to-severe OSA (AHI 15 or higher) via sleep study within the past 12 months
2. BMI 30 or higher at the time of prescription
3. Trial of CPAP or BiPAP for at least 90 days with documented adherence data showing either:

• Adherent use (4+ hours per night on 70%+ of nights) but persistent AHI above 15, OR
• Non-adherence due to documented intolerance (mask fit issues, claustrophobia, skin irritation)

1. Prescription written by a sleep medicine specialist, pulmonologist, or obesity medicine specialist (some plans may allow endocrinologists or primary care with sleep study documentation)
2. Commitment to repeat sleep study at 6 months to document AHI response

The CPAP-failure requirement will be the most common barrier. Patients who have never tried CPAP, or who tried it briefly and stopped without formal documentation, will need to complete a supervised CPAP trial before Mounjaro becomes a covered option.

Some commercial plans may waive the CPAP trial requirement for patients with documented CPAP contraindications (severe nasal obstruction, central sleep apnea component, congestive heart failure with Cheyne-Stokes respiration), but this will be plan-specific.

Medicare coverage is harder to predict. The Centers for Medicare & Medicaid Services (CMS) has historically been conservative with obesity drug coverage. As of April 2026, Medicare Part D does not cover Zepbound for obesity. If CMS classifies Mounjaro for OSA as an obesity drug with a sleep benefit (rather than a sleep drug), Part D plans may exclude it under the statutory obesity drug exclusion.

If CMS classifies it as a sleep apnea drug, coverage becomes possible, but the same CPAP-trial requirements will apply.

The Mounjaro vs Zepbound naming complexity for sleep apnea

Tirzepatide is sold under two brand names: Mounjaro (approved for diabetes) and Zepbound (approved for obesity). Both contain identical tirzepatide formulations at identical doses.

Eli Lilly submitted the sleep apnea indication under the Mounjaro brand name, not Zepbound. This creates a coverage complexity.

If your insurance covers Mounjaro for diabetes but not Zepbound for obesity, and the sleep apnea indication is approved under Mounjaro, you may have access to the drug for OSA even if your plan excludes obesity drugs.

Conversely, if your plan covers Zepbound but your provider writes the prescription as "Mounjaro for obstructive sleep apnea," the pharmacy claim may reject if your plan's formulary lists only Zepbound.

The practical workaround: once the sleep apnea indication is approved, providers can write the prescription as "tirzepatide for obstructive sleep apnea" and let the pharmacy fill with whichever brand name the patient's plan covers. The formulation is identical.

This naming split exists because Eli Lilly wanted to preserve Mounjaro's association with metabolic disease (diabetes, now OSA as a metabolic complication of obesity) and position Zepbound as the pure weight-loss brand. From a regulatory perspective, they are the same drug with different trade dress.

Compounded tirzepatide access while waiting for approval

Patients with obesity and comorbid sleep apnea do not need to wait until August 2026 to access tirzepatide. Compounded tirzepatide is available now through telehealth platforms, prescribed off-label for weight management in patients with OSA as a comorbidity.

How compounded access works: A licensed provider evaluates your medical history, BMI, and comorbid conditions (including sleep apnea). If you meet criteria for obesity treatment (BMI 30 or higher, or BMI 27 or higher with weight-related comorbidity), the provider can prescribe compounded tirzepatide off-label.

The prescription is sent to a state-licensed 503A compounding pharmacy, which prepares tirzepatide from bulk active pharmaceutical ingredient (API). You receive a vial and insulin syringes. Dosing follows the same escalation schedule as brand-name Mounjaro (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg weekly).

Pricing: FormBlends compounded tirzepatide costs $279 to $349 per month depending on dose, with no insurance involvement. This is significantly less than the $1,050+ monthly cost of brand-name Mounjaro or Zepbound without insurance.

Other telehealth platforms charge $299 to $499 per month for compounded tirzepatide.

Key differences from brand-name: Compounded tirzepatide is not FDA-approved. It is prepared in response to an individual prescription under the Federal Food, Drug, and Cosmetic Act's compounding exemptions. It has not undergone the same manufacturing and quality review as brand-name products.

You draw the dose from a vial using a U-100 insulin syringe rather than using a pre-filled pen. This requires comfort with self-injection technique.

When compounded makes sense:

• Your insurance doesn't cover Mounjaro or Zepbound, or your copay is over $200 per month
• You have obesity and sleep apnea but haven't completed a formal sleep study yet (compounded access doesn't require sleep study documentation)
• You want to start treatment now rather than waiting for FDA approval and insurance policy updates
• You're comfortable with off-label use and manual injection

When brand-name makes more sense:

• Your insurance covers Mounjaro or Zepbound with a copay under $100
• You qualify for Eli Lilly's savings card (commercial insurance patients can reduce copay to $25 per month)
• You strongly prefer FDA-approved medications
• You want the convenience of a pre-filled pen

The clinical effect is the same. Both deliver tirzepatide at the same doses. The difference is regulatory status, delivery mechanism, and cost structure.

The clinical pattern we see in patients using tirzepatide for comorbid OSA

FormBlends providers have prescribed compounded tirzepatide to over 800 patients with documented or suspected obstructive sleep apnea as a comorbidity (as of April 2026). While we cannot make specific statistical claims, we observe consistent patterns in this population.

Pattern 1: AHI improvement correlates tightly with weight loss velocity. Patients who lose 15% or more of body weight in the first 6 months report the most dramatic subjective improvement in sleep quality and daytime alertness. Patients who lose 5% to 10% report moderate improvement. Patients who lose less than 5% report minimal sleep benefit even if they see other metabolic improvements (glucose control, blood pressure).

This tracks with the SURMOUNT-OSA data showing dose-dependent effects. Higher doses produce more weight loss, which produces larger AHI reductions.

Pattern 2: CPAP adherence improves in patients who continue both therapies. Patients using CPAP before starting tirzepatide often report that CPAP becomes more comfortable as they lose weight. Mask fit improves (less facial fat means better seal), and the required pressure settings often decrease.

Several patients have had their CPAP pressure titrated down by their sleep physician after 3 to 6 months on tirzepatide, which further improves comfort and adherence.

Pattern 3: Subjective improvement precedes objective AHI measurement. Most patients report better sleep quality, less daytime fatigue, and reduced snoring within 8 to 12 weeks of starting tirzepatide, often before they've had a repeat sleep study to document AHI change.

This creates a clinical dilemma: patients feel better and want to continue, but payers (once the indication is approved) will require objective AHI documentation to authorize continued coverage. We anticipate this will drive demand for home sleep apnea testing at the 6-month mark.

Pattern 4: Patients who stop tirzepatide see gradual return of symptoms. Weight regain after stopping tirzepatide is common, and with weight regain comes return of OSA severity. This mirrors the STEP trials' extension data showing weight regain after semaglutide discontinuation (Wilding et al., Lancet 2022).

This suggests tirzepatide for OSA is a chronic therapy, not a curative intervention. Patients will need ongoing treatment to maintain AHI reduction, similar to how CPAP requires nightly use.

These patterns inform how we counsel patients considering tirzepatide for comorbid sleep apnea. The medication works, but it works through sustained weight loss, which requires sustained treatment.

When you should NOT wait for FDA approval

Three patient scenarios where starting compounded tirzepatide now makes more sense than waiting for brand-name approval.

Scenario 1: You have severe OSA with cardiovascular comorbidities. If your AHI is over 30 and you have hypertension, atrial fibrillation, or history of stroke, the cardiovascular risk from untreated OSA is immediate. Waiting 4 to 6 months for FDA approval, then another 6 to 12 months for insurance coverage, then another 90 days for a required CPAP trial adds up to 12 to 18 months of ongoing hypoxemic stress.

Starting compounded tirzepatide now (alongside CPAP if you tolerate it, or as monotherapy if you don't) addresses the metabolic root cause immediately.

Scenario 2: You've tried CPAP and cannot tolerate it, and you don't want surgical options. If you've done a legitimate CPAP trial with mask fitting and pressure adjustments and still cannot use it consistently, your options are limited. Oral appliances work for mild OSA but are less effective for moderate-to-severe disease. Hypoglossal nerve stimulation (Inspire) requires surgery and costs $30,000 to $40,000.

Tirzepatide offers a non-surgical, non-device option. Waiting for FDA approval doesn't change the fact that you need treatment now.

Scenario 3: Your insurance has already denied Zepbound for obesity, and you expect the same denial for Mounjaro for OSA. If your plan has a blanket obesity drug exclusion, FDA approval of the sleep apnea indication may not change your coverage. Some plans will continue to classify tirzepatide as an obesity drug regardless of indication.

In this case, compounded tirzepatide at $279 to $349 per month is your most accessible option, and waiting for approval doesn't improve your situation.

The counterargument: if you have good insurance, a low expected copay, and mild-to-moderate OSA that is not immediately dangerous, waiting for approval may get you access to brand-name Mounjaro at $25 to $75 per month (with savings card or good formulary placement), which is cheaper than compounded.

This is a patient-specific calculation based on OSA severity, insurance quality, and financial situation.

Decision tree: brand-name vs compounded tirzepatide for OSA patients

Start here: Do you have documented OSA via sleep study?

• Yes, AHI 15 or higher → Continue to next question
• No, but strong suspicion (loud snoring, witnessed apneas, daytime sleepiness) → Get a home sleep test or in-lab study first. You'll need this documentation for insurance coverage post-approval anyway. While waiting for the study, you can start compounded tirzepatide for obesity if BMI qualifies.
• No, and no symptoms → Tirzepatide for OSA is not indicated. Consider for diabetes or obesity if you meet those criteria.

Do you currently use CPAP or BiPAP?

• Yes, and it works well (AHI controlled, I tolerate it) → Wait for FDA approval. You'll likely get coverage as adjunctive therapy to further reduce AHI and potentially lower required pressure. Starting compounded now offers limited additional benefit if CPAP is already controlling your OSA.
• Yes, but my AHI is still elevated despite adherent use → Start compounded tirzepatide now. You meet the likely PA criteria (CPAP trial, persistent OSA), and you'll benefit from the additive effect shown in SURMOUNT-OSA Trial 2.
• I tried CPAP and cannot tolerate it (mask discomfort, claustrophobia, skin issues) → Start compounded tirzepatide now. Waiting for approval adds months of untreated OSA. Document your CPAP intolerance formally with your sleep physician so you have the records for future PA submissions.
• No, I've never tried CPAP → If your OSA is moderate-to-severe, try CPAP first. It's still the most effective therapy and will be required for insurance coverage post-approval. If you cannot tolerate it after a legitimate trial, switch to compounded tirzepatide.

What is your insurance situation?

• I have commercial insurance that covers obesity drugs → Wait for FDA approval if you can tolerate the timeline. Your plan will likely cover Mounjaro for OSA with PA, and you may qualify for the Eli Lilly savings card to reduce copay to $25/month.
• I have Medicare → Coverage is uncertain even post-approval. Consider compounded tirzepatide at $279 to $349/month as your most reliable access path.
• I have Medicaid → Coverage varies by state. Some states cover obesity drugs, some don't. Check your state's Medicaid formulary. If not covered, compounded is your option.
• I have no insurance → Compounded tirzepatide at $279 to $349/month is far cheaper than brand-name cash price ($1,050+/month). Start compounded.

What is your BMI?

• 30 or higher → You meet the likely indication criteria. Proceed based on insurance and CPAP status above.
• 27 to 29.9 with weight-related comorbidity (hypertension, diabetes, dyslipidemia) → You may qualify for compounded tirzepatide under obesity indication, but you likely won't meet the sleep apnea indication post-approval (trials required BMI 30+). Compounded is your best path.
• Under 27 → You don't meet obesity treatment criteria. Tirzepatide for OSA is not appropriate unless you have type 2 diabetes (then Mounjaro is indicated for diabetes, and OSA improvement is a secondary benefit).

This tree assumes you're working with a licensed provider who can assess your full clinical picture. Edge cases (central sleep apnea, complex sleep apnea, obesity hypoventilation syndrome) require specialist evaluation.

FAQ

When will Mounjaro be approved for sleep apnea? The FDA's target decision date is August 15, 2026. Approval could come earlier (July 2026) or be delayed if the agency requests additional data. Most analysts expect approval between July and September 2026.

Will insurance cover Mounjaro for sleep apnea immediately after FDA approval? No. Payers typically take 6 to 12 months after FDA approval to update their medical policies and add new indications to formularies. Expect widespread commercial insurance coverage by Q2 2027, with prior authorization requirements including sleep study documentation and CPAP trial.

Can I get Mounjaro for sleep apnea right now before FDA approval? Brand-name Mounjaro requires an FDA-approved indication (currently diabetes or obesity under the Zepbound brand). Compounded tirzepatide can be prescribed off-label for obesity with comorbid sleep apnea through telehealth platforms like FormBlends.

How much does Mounjaro reduce sleep apnea severity? In the SURMOUNT-OSA trials, patients on tirzepatide 15 mg experienced a mean 55% reduction in apnea-hypopnea index (AHI) compared to 10% on placebo. The mean AHI dropped from 49 to 22 events per hour, moving most patients from severe to moderate OSA.

Is Mounjaro better than CPAP for sleep apnea? No. CPAP can reduce AHI to near zero in adherent users. Mounjaro reduces AHI by about half but does not eliminate OSA in most patients. Mounjaro is best used as adjunctive therapy (combined with CPAP) or as an alternative for patients who cannot tolerate CPAP.

Will Medicare cover Mounjaro for sleep apnea? Unknown. Medicare Part D does not currently cover obesity drugs. If CMS classifies Mounjaro for OSA as an obesity drug, coverage is unlikely. If CMS classifies it as a sleep apnea drug, coverage becomes possible but will require prior authorization and CPAP trial documentation.

Do I need a sleep study to get Mounjaro for sleep apnea? Once approved, yes. Insurance companies will require documented AHI from a sleep study (in-lab polysomnography or home sleep test) to authorize coverage. For compounded tirzepatide prescribed off-label for obesity, a sleep study is not required but is recommended to establish baseline severity.

Can Mounjaro cure sleep apnea? No. Mounjaro treats sleep apnea by reducing obesity, which reduces upper airway obstruction. If you stop Mounjaro and regain weight, OSA severity will return. It is a chronic therapy, not a cure.

What dose of Mounjaro is used for sleep apnea? The SURMOUNT-OSA trials used tirzepatide 10 mg or 15 mg weekly. Most patients saw greater benefit at 15 mg. The dose is escalated gradually (2.5 mg → 5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg) over 20 to 24 weeks to minimize side effects.

Can I use Mounjaro for sleep apnea if I don't have obesity? The FDA approval will likely restrict the indication to adults with BMI 30 or higher, matching the trial inclusion criteria. Patients with OSA and BMI under 30 will not qualify for the sleep apnea indication, though they may qualify for Mounjaro under the diabetes indication if they have type 2 diabetes.

How long does it take for Mounjaro to improve sleep apnea? Most patients in the SURMOUNT-OSA trials saw significant AHI reduction by 24 weeks (6 months). Subjective improvement in sleep quality and daytime alertness often occurs earlier, around 8 to 12 weeks, as weight loss begins.

Will I still need CPAP if I take Mounjaro? Possibly. Mounjaro reduces OSA severity but does not eliminate it in most patients. If your AHI remains above 15 after weight loss, CPAP is still recommended. The SURMOUNT-OSA trials showed that combining Mounjaro with CPAP produces the best outcomes.
