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.

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.

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.

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.

Safety topic

GLP-1 medications and anesthesia aspiration risk

Delayed gastric emptying on GLP-1 increases the risk of aspiration during anesthesia. ASA 2023 guidance recommends holding weekly GLP-1 ≥1 week and daily GLP-1 ≥24 hours before elective procedures requiring anesthesia.

Real, documented risk

How it happens

GLP-1 delays gastric emptying. Patients arrive in the operating room with retained gastric contents despite fasting per standard NPO guidelines. Aspiration of gastric contents during induction can cause aspiration pneumonitis or pneumonia.

Red flags — when to seek care

Scheduled elective surgery or procedure requiring anesthesia
Endoscopy or colonoscopy with sedation
Emergency surgery while on GLP-1 (anesthesiologist must know about GLP-1 use)

What to do

1.Tell your anesthesiologist about GLP-1 use ≥2 weeks before any scheduled procedure
2.Standard ASA 2023 guidance: hold weekly GLP-1 (Wegovy/Ozempic/Zepbound/Mounjaro) ≥1 week pre-procedure; hold daily Saxenda ≥24 hours
3.For emergency surgery: anesthesiologist may use additional aspiration precautions (rapid-sequence induction, gastric suctioning)
4.Restart GLP-1 once you are tolerating regular oral intake post-procedure
