What Are the Side Effects of the Morning-After Pill?
I had unprotected sex and am considering emergency contraception pills, but I'm concerned about how they might affect my body. How likely are side effects? If problems occur, what are the most common side effects?
Emergency contraceptive pills (ECPs) are often referred to as "the morning-after pill." The most common side effects of ECPs are nausea and vomiting. Dizziness, headaches, cramps, and fatigue can also occur.
Progestin-only ECPs, such as Plan B One-Step™ and Next Choice®, cause fewer side effects than combined oral contraceptive pills that contain both estrogen and progestin. If you throw up shortly after taking ECPs, call your healthcare provider or pharmacist.
