How Much Does Tirzepatide Cost?

Tirzepatide Brand-Name List Prices

Tirzepatide is available in two FDA-approved brand names with approximately similar list prices:

• Mounjaro (type 2 diabetes): ~$1,000–$1,100/month at list price. Verify at Lilly's Mounjaro pricing page.
• Zepbound (weight management): ~$1,000–$1,100/month at list price for pen injectors. Eli Lilly has offered self-pay vials at different price points — verify current availability. See Lilly's Zepbound pricing page.

The brand prescribed depends on your indication and your clinician's prescribing decision — but the list prices are comparable.

Insurance Coverage for Tirzepatide Products

Coverage differs significantly between the two tirzepatide products based on their FDA-approved indications:

• Mounjaro for type 2 diabetes: More commonly covered by commercial insurance with prior authorization. Medicare Part D covers Mounjaro for T2D in most plans.
• Zepbound for weight management: Coverage is less consistent. Many commercial plans and Medicare Part D do not cover weight-management medications, though this is evolving.

See our Mounjaro cost guide, Zepbound cost guide, and GLP-1 insurance guide for more detail.

Compounded Tirzepatide: Cost and Cautions

Compounded tirzepatide has been marketed at lower prices than branded Mounjaro or Zepbound. However, compounded tirzepatide is not FDA-approved, is not a generic equivalent, and carries different risks. The FDA has issued warnings about compounded tirzepatide products, including dosing errors and illegal marketing. Lower price does not mean equivalent safety or efficacy.

For a full discussion, see our compounded GLP-1 guide. If a provider offers compounded tirzepatide, ask about the current legal basis and the compounding pharmacy's accreditation status before proceeding.
