allergic reaction to glp-1 Rash from a explained by an allergist π, Thanks my friend @rubin_allergy for the information in this video Dermal Hypersensitivity Reaction to Semaglutide:
Description
Two-thirds of patients drank less on dulaglutide than when they were on placebo (Figure 2B)

Crit Rev Food Sci Nutr 58:12941309
Note that semaglutide and tirzepatide typically have different standard dosing levels, which is handled in the regression model by the drugType:dose interaction term

The SURMOUNT-4 trial assessed the weight maintenance with tirzepatide and had also two periods: a 36-week open-label lead-in period during which all participants took tirzepatide, followed by a 52-week double-blind treatment period during which participants were randomised to either continue on tirzepatide or switch to placebo
Both approaches activate the same GLP-1 receptor pathways
