Choose Based on Your Goal

You have type 2 diabetes

Mounjaro is the T2D-approved brand with strong SURPASS trial data. Most T2D insurance plans cover it; your endocrinologist will typically prescribe Mounjaro.

Weight loss is the primary goal

Zepbound is specifically dosed and approved for obesity. SURMOUNT-1 showed 20.9% mean weight loss — the highest of any approved obesity drug.

Obstructive sleep apnea

Zepbound gained the first-ever FDA approval specifically for obstructive sleep apnea in 2024. Mounjaro does not have this indication.

Insurance covers T2D but not obesity

Mounjaro is often prescribed off-label for weight loss when the plan does not cover Zepbound. Same drug, different label.

Cost for self-pay patients

Eli Lilly launched lower-cost Zepbound single-dose vials specifically for self-pay patients. Check Lilly's direct pharmacy programme for current pricing.

Switching between them

Switching from Mounjaro to Zepbound (or vice versa) requires no dose adjustment — it is literally the same drug. Update your prescription brand in Shotlee.

Why Two Brand Names?

Pharmaceutical companies seek separate FDA approvals for different indications — even when the drug is identical. This allows them to market the product to different specialties (endocrinology vs obesity medicine), negotiate insurance coverage separately, and set different formulary positions. The pharmacology is completely unchanged.

Zepbound gained an additional approval in 2024 for obstructive sleep apnea — the first medication ever specifically approved for this condition — making it the more versatile option for patients with multiple weight-related conditions.

If you have type 2 diabetes, your doctor will typically prescribe Mounjaro for better insurance coverage. If your primary goal is weight loss or you have sleep apnea, Zepbound is the on-label choice. In practice, the drugs are interchangeable — the brand name determines coverage.

Track Either in Shotlee

Shotlee supports both Mounjaro and Zepbound with the full 2.5–15 mg dose escalation schedule, injection reminders, weight tracking, and side effect logs. Switching brands does not affect your history.
