Emergency Contraception 101

How Emergency Contraception Works

The morning-after pill, also known as levonorgestrel, is an over-the-counter emergency contraceptive designed to prevent pregnancy after unprotected sex. When taken within 72 hours, it can reduce the risk of pregnancy by up to 89%. The key is to act fast – the sooner you take it, the better.

The Science Behind It

Levonorgestrel is a hormone that prevents ovulation, fertilization, and implantation of a fertilized egg. It won’t affect an already implanted fertilized egg, though. A single dose provides the full amount of levonorgestrel needed, and taking more won’t increase its effectiveness.

Taking Emergency Contraception Multiple Times

Physically, it’s safe to take emergency contraception more than once, but it’s not recommended as a regular form of contraception. Relying on it can lead to a higher risk of pregnancy, irregular periods, and a significant financial burden. If you find yourself needing emergency contraception frequently, it may be a sign that your regular birth control method isn’t suitable.

When to Take Emergency Contraception

The morning-after pill works best when taken as soon as possible after unprotected sex. The sooner you take it, the better – within 3 days is ideal, but it can still be effective up to 5 days later. A single dose consists of two pills taken 12 hours apart.

Possible Side Effects

Emergency contraception is generally safe, but it can cause some unpleasant side effects. Around 1 in 4 women experience nausea, while others may feel tired, dizzy, or have headaches, abdominal cramping, or breast tenderness. Your period might also be affected, coming later or heavier than usual. If you experience severe abdominal cramps, bleeding, or spotting that lasts longer than a week, seek medical attention.

Important Reminders

Emergency contraception is not a substitute for regular birth control. While it’s effective in emergency situations, it’s not a reliable method for preventing pregnancy or protecting against STIs. If you find yourself relying on it frequently, it may be time to reassess your birth control plan. Consult with your doctor to find a more suitable option that works for you.

Remember to always take emergency contraception as directed and be aware of its limitations and potential side effects. If you’re relying on it too often, it may be time to explore alternative options with your doctor.
