Contraception and GLP-1 Agonist Information

What are GLP-1 agonists?

• These are prescription medicines used in type 2 diabetes or weight management.

Contraception considerations

• If you’re using Tirzepatide: use an additional barrier method (e.g., condoms) on top of the pill for 4 weeks after you start the medication, and again for 4 weeks after any dose increase.
• Non-oral contraceptive methods (coil–implant, injection, patch, ring) are not shown to be affected by GLP-1 agonists.
• If you’re planning pregnancy: GLP-1 agonists should not be used during pregnancy. Effective contraception is vital while on them, and you should stop them for the recommended wash-out period before trying for pregnancy. (E.g., Tirzepatide – 1 month, Semaglutide – 2 months)

What to do next?

• If you’re taking a GLP-1 agonist and using any form of contraception (especially oral), please discuss this with your clinician or practice nurse. We can review your method.
