Zepbound: what it is, cost and alternatives
Zepbound is the brand name for tirzepatide — a dual gip / glp-1 receptor agonist — FDA-approved for chronic weight management. Typical cost: $299/month (2.5 mg), $399 (5 mg) and $449 (7.5-15 mg) through LillyDirect self-pay — but the $449 tier holds only if you refill within 45 days of your last delivery, otherwise $499-$699. Retail pen list price is about $1,086. As low as $25/fill with commercial coverage.. Because it shares an active ingredient with other brands and with compounded preparations, patients often compare pathways on price and access.
What is Zepbound, and who is it for?
Tirzepatide is a dual GIP and GLP-1 receptor agonist — it activates two incretin receptors rather than one. It is FDA-approved as Mounjaro for type 2 diabetes and as Zepbound for chronic weight management. In the pivotal SURMOUNT-1 trial, the highest dose produced about 20.9% average body-weight reduction over 72 weeks.
