Cost is often the deciding factor for many people — and the landscape is changing fast.
At the high end, branded injectable GLP-1 drugs (semaglutide injection, tirzepatide) have list prices of $1,000–$1,350+ per month. These are the prices without insurance.
Monthly costs range from about $30 for older generics to over $1,000 for newer injectable medications — but manufacturer savings programs can significantly reduce out-of-pocket costs.
But the landscape shifted significantly in late 2025. Oral semaglutide (the Wegovy pill) launched at roughly $149 per month self-pay — making a GLP-1 option accessible to many more people. Generic liraglutide also became available in 2025, bringing down injection costs for that drug.
At the other end, generic phentermine/topiramate costs about $30–$80 per month. Orlistat (OTC version, Alli) costs about $40–$60 per month with no prescription needed.
Manufacturer savings programs (Eli Lilly's LillyDirect, Novo Nordisk's NovoCare) can reduce costs significantly for eligible patients. Insurance coverage is expanding but remains inconsistent — it varies by plan, country, and employer.
