The short answer
Continue your SSRI. No dose change needed.
Generally safeNo known interaction
Why it matters
Different metabolic pathways. SSRIs metabolized via CYP2D6/3A4; GLP-1s are peptide drugs (semaglutide, tirzepatide) cleared without significant CYP involvement, or orally absorbed small molecule (orforglipron) with minimal CYP impact.
What to do
Continue current SSRI. Monitor for emerging GI side effects in the first 2 weeks, as both can affect appetite/nausea.
Ask your prescriber
“I take SSRIs. Is Wegovy safe with it, and what should we monitor?”

Before you start Wegovy
A licensed prescriber reviews your full medication and supplement list before prescribing a GLP-1. If you take SSRIs, mention it at your consultation.

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
- 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
- What happens if I miss a weekly GLP-1 dose?
- If within 5 days: take the missed dose as soon as you remember, then resume the regular schedule. More than 5 days late: skip it and inject your next scheduled dose. Never double up. Full evidence-graded answer
- Can GLP-1 cause thyroid cancer?
- The boxed warning is based on rodent studies showing medullary thyroid carcinoma (MTC) in mice and rats. No human cases have been attributed to GLP-1 use despite 10+ years post-approval surveillance. Full evidence-graded answer
