In the past, if you were prescribed an antibiotic other than rifampicin or rifabutin (eg amoxicillin, erythromycin, doxycycline) while using the patch, the advice used to be that you use an extra method of contraception (eg condoms) while you were taking the antibiotic and for seven days after finishing the course. However, this advice has now changed. You no longer need to use an extra method of contraception with the patch while you take a course of antibiotics. This change in advice comes because to date there is no evidence to prove that antibiotics (other than rifampicin or rifabutin) affect the patch. This is the latest guidance from the Faculty of Sexual & Reproductive Healthcare.
