Hormonal

Semaglutide (2.4 mg/week) provides significantly better economic value for weight reduction than liraglutide (3 mg/day), with a lower cost needed to treat per 1% body weight reduction.

If you are choosing between semaglutide and liraglutide for weight loss in the US, semaglutide is the more economically efficient option. It achieves nearly double the weight loss (12.4% vs 5.4%) for a lower cost per percentage point of weight lost, despite having a higher total therapy cost. The weekly injection schedule may also improve convenience and adherence compared to daily injections.
