Levonorgestrel

Levonorgestrel is used in women to prevent pregnancy after birth control failure (e.g., broken condom) or unprotected sex. It is a progestin hormone that prevents pregnancy by preventing the release of an egg (ovulation) and changing the womb and cervical mucus to make it more difficult for an egg to meet sperm (fertilization) or attach to the wall of the womb (implantation). Using Levonorgestrel will not stop an existing pregnancy or protect you against sexually transmitted diseases (e.g., HIV, gonorrhea, chlamydia). This medication should not be used as a regular form of birth control.

How To Use:
Take 1 tablet by mouth as soon as possible after unprotected sex. Take the second tablet by mouth 12 hours after taking the first dose. This medication may be taken with or without food. Levonorgestrel works best when it is taken within 72 hours (3 days) after unprotected sex. In some cases, your doctor may instruct you to take both tablets at once. Take the medication exactly as prescribed by your doctor. If you vomit within 1 hour of taking either dose of the medication, contact your doctor to discuss whether you need to repeat the dose. The amount and timing of your period may be irregular after taking this medication. Notify your doctor immediately if your period is more than 7 days late. You may need to take a pregnancy test.

Side Effects:
Nausea/vomiting, abdominal pain, tiredness, dizziness, changes in vaginal bleeding, breast tenderness, diarrhea, or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Remember that your doctor has prescribed Levonorgestrel because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor immediately if any of these rare but very serious side effects occur: lower abdominal pain. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. This is not a complete list of possible side effects.
