MOUNJARO COST GUIDE
How Much Does Mounjaro Cost?
Mounjaro's approximate list price is $1,000–$1,100 per month without insurance. As an FDA-approved type 2 diabetes medication, it tends to have better insurance coverage prospects than weight-management medications. Eli Lilly offers a savings program for eligible commercially insured patients. This guide covers Mounjaro-specific cost factors.
Pricing disclaimer: Mounjaro's list price varies by dose and changes over time. No price on this page is guaranteed. Always verify current pricing with Eli Lilly, your pharmacy, or your insurance plan.
Mounjaro List Price Without Insurance
Mounjaro is available in multiple dose strengths (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg) as once-weekly injection pens. The approximate list price for a monthly supply ranges from about $1,000 to $1,100, with variation by dose. These figures represent list prices — what you would pay at a pharmacy without insurance or savings program assistance.

Insurance Coverage for Mounjaro
Mounjaro is FDA-approved for type 2 diabetes — a condition for which most commercial insurance plans provide some coverage. Key considerations:
- Type 2 diabetes indication: Most commercial insurance plans cover tirzepatide for T2D with prior authorization. Coverage terms and formulary tier vary by plan.
- Off-label for weight management: If prescribed without a T2D diagnosis for weight management only, insurance coverage is much less certain. Your plan may deny coverage for off-label use.
- Prior authorization: Required by most plans. Your clinician documents the clinical indication and submits for PA — approval is not guaranteed.
- Medicare: Part D covers Mounjaro for T2D for most plans. Weight management coverage for tirzepatide products remains limited under Medicare.
Eli Lilly Savings Program for Mounjaro
Eli Lilly offers a savings program for Mounjaro for eligible commercially insured patients. As with all manufacturer savings programs:

Mounjaro vs. Zepbound: Cost Considerations
Mounjaro and Zepbound contain the same active ingredient (tirzepatide) at the same doses, so their list prices are similar. The key cost difference is the insurance coverage implications of their different indications — Mounjaro is more commonly covered for T2D, while Zepbound faces greater challenges for weight management coverage. Choosing between them for a patient with both T2D and obesity is a clinical and insurance-access decision for a licensed clinician. See our Zepbound cost guide for comparison.
