Does drinking alcohol affect my birth control and its effectiveness?
Drinking alcohol will not decrease the efficacy of the pill, patch, or ring. However, if while drinking you forget to take your pill or vomit within two hours of taking your pill, the efficacy of your birth control will decrease, because you will have missed a pill. See "What do I do if I missed a pill?" for more information or reach out to us so our doctors can provide you with guidance.
