Alcohol is not contraindicated, but tolerance decreases substantially for most people on Retatrutide
A randomized clinical trial published in JAMA Psychiatry demonstrated reduced alcohol craving and consumption among participants receiving semaglutide, with secondary reductions in cigarette use among smokers (Hendershot et al., 2024)
There is a risk of weight regain if the medication is discontinued
