Wegovy: List price ~$1,350/month without insurance. With Novo Nordisk's patient assistance program, eligible self-pay patients can access at $200-500/month.

Real out-of-pocket depends on insurance formulary tier, manufacturer savings programs, and whether a direct-pay channel is available.
Can I switch from Wegovy to Retatrutide?+
Switching between brand-name treatments in the same drug class is common, but the conversion is not always 1:1. Discuss the switch with your prescriber — they'll usually re-titrate dosing rather than substitute equivalent strengths directly.
