Should I use additional contraception when starting Mounjaro?
Yes, if you are using oral contraceptives like the combined pill or mini-pill when starting Mounjaro, you should use additional contraception such as condoms for four weeks after starting and after each dose increase. Non-oral methods like patches, injections, rings, implants, or IUDs are not affected and do not require extra precautions. Speak to your healthcare provider to discuss the best options for you during treatment.
Key points:
- Mounjaro reduces the effectiveness of oral contraceptives by slowing stomach emptying.
- Use a barrier method like condoms alongside oral pills for four weeks after starting or dose increases.
- Non-oral contraceptives such as patches, injections, rings, implants, or IUDs remain fully effective.
- Reliable contraception is essential while on Mounjaro as it is not safe during pregnancy.
