Birth Control Medications and Alcohol

Birth control methods such as the pill, intrauterine device (IUD), hormone implant, ring, or the patch -- when used correctly -- are about 91% to 99% effective.

  • While there can be other drug interactions, these forms of birth control are not usually affected by alcohol. However, for birth control pills and drinking alcohol, if you drink so much that you vomit within 2 hours of taking your pill, then the effectiveness of the pill could be compromised. If this should happen, take another pill as soon as possible and check with your healthcare provider as soon as possible about how to proceed.
  • Try to avoid drinking so much alcohol that it leads to vomiting; this can be dangerous. Alcohol can cloud your judgement, increase your risk for unsafe sex, and make driving dangerous.
  • Be sure to have a complete drug interaction review by your pharmacist each time you start a new medication, including over-the-counter medications, vitamins, and herbal supplements.
