Emergency Contraception

Emergency Contraception

Emergency contraception (EC), sometimes called the morning-after pill, is a safe and effective way to help prevent pregnancy after unprotected sex or contraceptive failure, such as a condom breaking or missing birth control pills.

Emergency contraception works best when taken as soon as possible.

Types of Emergency Contraception

• Levonorgestrel pills such as Plan B One-Step® and generics are available over the counter at most pharmacies. They work best within 72 hours (3 days).
• Ulipristal acetate, also known as Ella®, requires a prescription and can be used up to 120 hours (5 days) after unprotected sex.
• The copper IUD can be placed by a healthcare provider within 5 days and is the most effective form of emergency contraception.

How It Works

Emergency contraception mainly works by delaying or preventing ovulation, which means it helps stop the release of an egg before pregnancy can occur.

Emergency contraception does not cause an abortion and will not end an existing pregnancy.

Possible Side Effects

• Nausea
• Fatigue
• Headache
• Breast tenderness
• Dizziness
• Temporary changes to your next period

When to Take a Pregnancy Test

Take a pregnancy test if your period is more than one week late, or if it has been 3 weeks since unprotected sex and you have not had a normal period.

Important Reminders

• Emergency contraception does not protect against sexually transmitted infections (STIs).
• It is safe to use more than once if needed.
• For ongoing protection, consider using a regular birth control method.
