The short answer
Tirzepatide users: add a barrier method for 4 weeks after starting and after each dose increase. Semaglutide users: no contraceptive interaction documented.
Use with cautionUsually fine — watch for specific effects
Why it matters
Limited PK data on coadministration with oral contraceptives — orforglipron does not delay gastric emptying as profoundly as tirzepatide.
What to do
Until more data is published, conservative approach is to add a barrier method for the first month. Review with prescriber at 8 weeks.
Ask your prescriber
“I take Birth control. Is Foundayo (orforglipron) safe with it, and what should we monitor?”
