Do antibiotics affect my birth control?

This depends on the antibiotic.

Rifampin or Rifabutin:
Yes, these may decrease the effectiveness of your birth control. You need to make sure to let us know via a direct message once you are logged into your account.

Doxycycline, Minocycline, Amoxicillin, Augmentin, Cephalexin, Bactrim or Clindamycin:
Antibiotics have a questionable association with increased pregnancy risk. There is no greater incidence of pregnancy in women taking birth control alone, as those taking birth control with these antibiotics. If it helps ease your mind, we would recommend using condoms during antibiotic treatment and for 7 days following treatment. This will give you peace of mind and make sure you get the maximum effectiveness out of your birth control. This will also help prevent any STI’s if you aren’t 100% sure of your partner’s STI status. One issue worth mentioning is birth control and doxycycline or minocycline together may cause increased sensitivity to the sun. We would like to remind you to be extra vigilant about sunscreen while you are taking them, as they can both make you more sensitive to sunlight.
