How much does Mounjaro cost?
Medically reviewed by Editorial Medical Review, MD, NAMS-CMP
Quick answer
$25-$1,086/mo. Mounjaro lists at $1,086/month in 2026, identical to Zepbound (both tirzepatide). Most commercial insurance plans and Medicare Part D cover Mounjaro for type 2 diabetes with standard formulary tier ($25-$100/month copays). Eli Lillys Mounjaro Savings Card reduces commercially-insured patient cost to as low as $25/month. Mounjaro is not indicated for weight loss — Zepbound is the weight-loss version.

Frequently asked questions
- Does Medicare cover Mounjaro?
- Yes — Medicare Part D covers Mounjaro for type 2 diabetes (not for weight loss). Standard formulary tier and copay vary by plan. Medicare does not cover Zepbound (weight-loss version of same drug).
- Can I use Mounjaro for weight loss?
- Mounjaro is FDA-approved only for type 2 diabetes. Some clinicians prescribe off-label for weight loss, but insurance typically denies coverage and requires switching to Zepbound.
- How does Mounjaro cost compare to Ozempic?
- Mounjaro lists at $1,086/month. Ozempic lists at $935/month. Both have manufacturer savings cards reducing commercially-insured cost to $25/month. Coverage criteria are similar (T2D diagnosis).
- Will Mounjaro get cheaper?
- Tirzepatide patent protection extends through 2036-2039 in the US — generic versions unlikely before then. Cash prices may decline if competitors (Lillys retatrutide, Novos amycretin) enter the dual-incretin space.
