Mounjaro cost without insurance (2026)

Mounjaro is tirzepatide approved for type 2 diabetes. Its cash pricing sits in an odd place: about half of list through the manufacturer's own channel, and still meaningfully more than the identical molecule sold as Zepbound.

Researched 2026-09-06 from published sources · how we verify · the full Mounjaro guide

If you're researching weight loss: Mounjaro is not approved for it. Zepbound is the same molecule with the weight-management approval — and at $299–$449 a month self-pay, it's also the cheaper route. Our Zepbound cost page has every channel.

The same molecule, priced two ways

Mounjaro and Zepbound are both tirzepatide from the same manufacturer. The label differs, the approved indication differs, and so does the self-pay program — Mounjaro is a flat $499 a month, while Zepbound is dose-tiered and starts lower:

Zepbound dose	LillyDirect self-pay	vs Mounjaro flat $499
2.5 mg	$299	$200/mo cheaper
5 mg	$399	$100/mo cheaper
7.5 mg	$449	$50/mo cheaper
10 mg	$449	$50/mo cheaper
12.5 mg	$449	$50/mo cheaper
15 mg	$449	$50/mo cheaper

If you're prescribed Mounjaro for type 2 diabetes

Commercial insurance? The savings card is the first stop — as low as $25 a month with a type 2 diabetes prescription, subject to its terms and caps.
No coverage? LillyDirect self-pay at $499 flat beats retail by roughly half. It cannot be combined with active commercial, Medicare, or Medicaid coverage.
On Medicare? The GLP-1 Bridge $50 copay covers weight-loss products, not Mounjaro for diabetes — your Part D coverage is the normal route. Our insurance guide has the questions to ask.
