Common questions readers ask

Can you drink alcohol on Wegovy?
No hard contraindication, but alcohol tolerance often drops sharply on GLP-1. Many patients also report reduced desire for alcohol — likely a secondary effect of GLP-1 on the brain reward system.
Full evidence-graded answer
Does GLP-1 affect oral birth control?
Tirzepatide (Mounjaro, Zepbound) has documented reduced absorption of oral contraceptives during the first 4 weeks of each dose increase. Use backup contraception for ~4 weeks after starting + after each step-up. Semaglutide has no documented effect.
Full evidence-graded answer
Can I take GLP-1 while pregnant?
No. All FDA-approved GLP-1s carry a pregnancy contraindication. Stop GLP-1 at least 2 months before planned conception due to its long half-life.
Full evidence-graded answer
Is it safe to take GLP-1 long-term?
Liraglutide has 15+ years of post-marketing data (Victoza approved 2010). Semaglutide has 8+ years (Ozempic approved 2017). No new class-wide safety signals have emerged in extended follow-up. Chronic use is the FDA-approved indication for both T2D and obesity.
Full evidence-graded answer
Do I need to exercise on Wegovy?
Yes — resistance training specifically. Without it, 25-40% of weight lost on GLP-1 comes from lean muscle. Cardio is a bonus; resistance is the non-negotiable.
