When Will Mounjaro Be Approved for Weight Loss?
Mounjaro (tirzepatide) is a medication primarily used for type 2 diabetes, but its weight loss benefits have sparked widespread interest.
Many are eager to know when will Mounjaro be approved for weight loss by the FDA. This article explores its current status, clinical trial results, and what to expect. With clear, simple language, we’ll guide you through the approval process and its implications.
What Is Mounjaro and Why the Hype for Weight Loss?
Mounjaro is a weekly injectable drug developed by Eli Lilly. It mimics two hormones, GLP-1 and GIP, to control blood sugar and appetite. Approved in May 2022 for type 2 diabetes, it’s often prescribed off-label for weight loss. Its ability to help users shed significant weight has fueled demand.
Clinical trials show Mounjaro can lead to 15–22% body weight loss. This is higher than other drugs like Ozempic or Wegovy. The impressive results have led to the question: when will Mounjaro be approved for weight loss? Its potential as a game-changer keeps patients and doctors hopeful.
Current FDA Approval Status
Mounjaro is not yet FDA-approved for weight loss as of April 2025. However, its active ingredient, tirzepatide, is approved for weight loss under the brand name Zepbound. The FDA approved Zepbound in November 2023 for chronic weight management. This approval covers adults with obesity (BMI ≥30) or overweight (BMI ≥27) with related health conditions.
Zepbound’s approval has reduced the need for Mounjaro’s off-label use for weight loss. Still, many wonder when will Mounjaro be approved for weight loss directly. The focus has shifted to Zepbound, but Mounjaro’s weight loss approval remains under consideration.
Why Zepbound Instead of Mounjaro for Weight Loss?
Zepbound and Mounjaro contain the same active ingredient, tirzepatide. The difference lies in their FDA-approved uses. Mounjaro is for type 2 diabetes, while Zepbound is for weight loss. Eli Lilly markets them separately to meet distinct medical needs.
Zepbound’s approval was based on the same trials that support Mounjaro’s weight loss potential. This makes a separate Mounjaro weight loss approval less urgent. Doctors may prescribe Zepbound for weight loss instead of Mounjaro off-label. Still, some patients prefer Mounjaro due to insurance or availability.
Clinical Trials Supporting Weight Loss Approval
The SURMOUNT trials are key to understanding Mounjaro’s weight loss potential. SURMOUNT-1 showed non-diabetic adults lost 16–22% of body weight over 72 weeks. SURMOUNT-2, for those with type 2 diabetes, reported 13–15% weight loss. These results are among the highest for weight loss drugs.
Higher doses (10 mg or 15 mg) yielded better results. The trials also showed improvements in cholesterol, blood pressure, and blood sugar. These findings support the push for FDA approval. They fuel speculation about when will Mounjaro be approved for weight loss.
Fast-Track Designation and Approval Timeline
In October 2022, the FDA granted Mounjaro a fast-track designation for weight loss. This speeds up the review process for drugs addressing serious conditions like obesity. The fast-track status led to Zepbound’s approval in November 2023. Mounjaro’s weight loss approval could follow a similar path.
Experts predicted Mounjaro’s weight loss approval by late 2023, but Zepbound took precedence. As of April 2025, no specific date exists for Mounjaro’s weight loss approval. Ongoing trials may influence when will Mounjaro be approved for weight loss.

Why Mounjaro’s Weight Loss Approval Matters
A weight loss approval for Mounjaro could improve insurance coverage. Many plans don’t cover off-label use, making Mounjaro costly ($1,000–$1,200 monthly). Approval could lower costs for patients without diabetes. It would also legitimize its use for weight management.
Zepbound’s approval already addresses this for many. However, Mounjaro’s established name recognition could drive demand. Approval would streamline prescribing for doctors. Patients keep asking when will Mounjaro be approved for weight loss due to these benefits.
Off-Label Use for Weight Loss
Doctors can prescribe Mounjaro off-label for weight loss now. This is common for patients with obesity or weight-related conditions. Off-label use relies on the SURMOUNT trial data showing significant weight loss. However, it’s not FDA-approved for this purpose.
Off-label prescribing faces challenges like limited insurance coverage. Zepbound is often preferred since it’s approved for weight loss. Still, Mounjaro’s off-label use continues in areas where Zepbound is unavailable. This keeps the question alive: when will Mounjaro be approved for weight loss?
Side Effects and Safety Considerations
Mounjaro’s side effects include nausea, diarrhea, vomiting, and constipation. These are usually mild and decrease over time. Higher doses, like 12.5 mg or 15 mg, may increase side effects. Serious risks include pancreatitis or thyroid tumors, though rare.
Zepbound has similar side effects, as it’s the same drug. Patients must discuss risks with their doctor. Safety data supports its weight loss use, but FDA approval would ensure broader monitoring. This is another reason people ask when will Mounjaro be approved for weight loss.
Lifestyle Changes for Best Results
Mounjaro works best with a healthy lifestyle. A reduced-calorie diet with vegetables, lean proteins, and whole grains enhances weight loss. Regular exercise, like 30 minutes of walking daily, boosts results. Avoiding sugary foods and drinks is essential.
Tracking meals and staying hydrated support progress. Mounjaro reduces appetite, making it easier to eat less. Lifestyle changes are critical whether using Mounjaro off-label or awaiting approval. They maximize benefits while you wonder when will Mounjaro be approved for weight loss.
Cost and Insurance Challenges
Mounjaro costs $1,000–$1,200 per month without insurance. Coverage is often limited for off-label weight loss use. Eli Lilly’s Savings Card can reduce costs to $25 for insured patients with diabetes. Zepbound may be covered for weight loss, but not always.
Approval for weight loss could improve coverage for Mounjaro. This would make it more affordable for non-diabetic patients. Cost is a key factor driving interest in when will Mounjaro be approved for weight loss. Check with your insurance for options.
Who Can Benefit from Mounjaro for Weight Loss?
Mounjaro is suitable for adults with obesity (BMI ≥30) or overweight (BMI ≥27) with conditions like high blood pressure or cholesterol. It’s prescribed off-label for these groups now. Zepbound targets the same population with FDA approval. A doctor assesses eligibility based on health history.
Those with thyroid cancer history or pregnancy should avoid Mounjaro. Approval would clarify its use for weight loss patients. This is why many ask when will Mounjaro be approved for weight loss. Always consult your doctor first.
What’s Next for Mounjaro’s Approval?
Eli Lilly is likely focusing on Zepbound for weight loss. However, Mounjaro’s weight loss approval could still happen. Ongoing trials, like SURMOUNT-5, compare tirzepatide to other drugs. Results could support a Mounjaro weight loss indication by late 2025 or 2026.
The FDA may prioritize other drugs or require more data. For now, Zepbound meets the weight loss need. Patients should discuss both options with their doctor. The timeline for when will Mounjaro be approved for weight loss remains uncertain.
