Yes. Foundayo delays gastric emptying, which may affect how oral hormonal contraception is absorbed and could reduce its effectiveness.
If you use oral hormonal contraception, you may be advised to switch to a non-oral contraceptive method or use an additional barrier method, such as condoms.
This is recommended for 30 days after starting Foundayo and for 30 days after each dose increase.
If you are unsure which contraceptive method is appropriate for you, please speak to a healthcare professional for advice.
