WHAT IS THE DOSAGE OF THIS MEDICATION?

Backup Plan and its generic levonorgestrel is available in the strength of 1.5 mg/1 tablet only.

WHAT IS THIS MEDICATION USED FOR?

Levonorgestrel belongs to the family of medications known as progestins. Progestins are female sex hormones that are used in birth control pills and often in combination with the hormone estrogen.

Levonorgestrel is a progestin-only emergency birth control pill intended for use within 72 hours of unprotected sexual intercourse. It should only be used by women whose regular birth control methods have failed or who may have had intercourse without birth control. It is not a substitute for correct use of regular birth control.

This medication is believed to prevent pregnancy primarily by delaying ovulation or preventing fertilization of the egg. It may also prevent implantation of the egg by altering the endometrium (inner lining of the uterus). It is important to realize that once implantation has occurred and pregnancy is established, levonorgestrel cannot cause an abortion or harm the fetus. No serious complications have been reported with this medication.

This medication reduces the risk of pregnancy among users from around 8% to around 1% after unprotected sexual intercourse. It is most effective in the first 24 hours after intercourse.

It should be noted that this medication does not protect against HIV infection (AIDS) or other sexually transmitted infections.

The 1.5 mg tablet contained in the kit should be taken as soon as possible within 72 hours of unprotected sexual intercourse. The medication is most effective if taken within 12-24 hours of unprotected sexual intercourse.

Because this medication is often associated with nausea, your doctor may also want you to take medication to prevent nausea at the same time as taking these pills. If you vomit within 2 hours of taking the tablet, you should contact your health care provider as you may need to take another dose. This medication can be used at any time during the menstrual cycle. It can be taken with or without food. Taking it with food may help reduce the nausea.

Most women have their expected menstrual period within 7 days of their normal time after using this medication. If you don't have your menstrual period within 7 days of when it is expected, you should have a pregnancy test done.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as recommended by your doctor. Levonorgestrel is not intended to be used routinely as birth control.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
