Mounjaro vs Ozempic: Which Is Better for Weight Loss and Diabetes?

Mounjaro (tirzepatide) is an FDA-approved medication for type 2 diabetes. It works by targeting two receptors: GLP-1 and GIP, both of which help regulate blood sugar, slow digestion, and reduce appetite.



Though not yet FDA-approved for weight loss, Mounjaro is frequently prescribed off-label for that purpose. Many clinical studies show that Mounjaro may produce more significant weight loss than other GLP-1 drugs, including Ozempic.


What Is Ozempic?

Ozempic (semaglutide) is also a once-weekly injectable drug originally approved for type 2 diabetes. It targets the GLP-1 receptor and helps with blood sugar control, reduced appetite, and gradual weight loss. Ozempic’s active ingredient (semaglutide) is also found in Wegovy, which is FDA-approved for weight loss.


Mounjaro vs Ozempic: Weight Loss Results

In head-to-head comparisons, Mounjaro has shown greater average weight loss than Ozempic at similar or even lower doses. Clinical data includes:



  • Mounjaro: Up to 20% total body weight loss at higher doses (15 mg)




  • Ozempic: Average of 10–15% total weight loss at maximum doses



This has made Mounjaro the subject of strong interest among those seeking the best weight loss injection, especially when Ozempic results plateau.


Dosing and Administration
























Medication Frequency Starting Dose Maximum Dose
Ozempic Weekly 0.25 mg 2.0 mg
Mounjaro Weekly 2.5 mg 15 mg

 

Both are self-administered using pre-filled injection pens. Doses are gradually increased over several weeks to reduce side effects.


Cost Comparison: Mounjaro vs Ozempic
























Medication Retail Cost (U.S.) Coupon Options Insurance Coverage
Ozempic ~$900/month Manufacturer savings card, GoodRx Often covered with PA
Mounjaro ~$1,100/month Lilly Savings Card, telehealth plans Coverage varies

 

Without insurance, Ozempic is slightly less expensive, but Mounjaro coupons can significantly reduce out-of-pocket costs for eligible patients (as low as $25/month for some with insurance).

Side Effects: How Do They Compare?

Both medications share common side effects:



  • Nausea




  • Diarrhea or constipation




  • Fatigue




  • Decreased appetite



Mounjaro may cause slightly more gastrointestinal effects due to its dual-action mechanism. However, gradual dose escalation helps reduce severity.

Rare but serious risks include pancreatitis, gallbladder issues, and thyroid tumors (based on animal studies). Neither is recommended during pregnancy or for patients with a history of medullary thyroid carcinoma.

  • You’re focused on maximum weight loss results




  • You’re open to trying newer dual-agonist therapies




  • Your insurance covers Mounjaro or you qualify for savings



Choose Ozempic if:



  • You prefer a longer-established medication




  • You’re already managing type 2 diabetes with semaglutide




  • You want an option that has extensive data and wide provider familiarity

Final Takeaway

Mounjaro and Ozempic are both effective tools for managing type 2 diabetes and promoting weight loss. Mounjaro may offer greater weight loss due to its dual-action formulation, but both drugs are widely used depending on individual needs, provider guidance, and cost access.

If you're deciding between the two, consider your health history, insurance situation, and whether weight loss or glucose control is your primary goal.
