TAKE ACTION is emergency contraception that helps prevent pregnancy after birth control failure or unprotected sex. It is a backup method of preventing pregnancy and should not be used as regular birth control.

What TAKE ACTION is not.

TAKE ACTION will not work if you are already pregnant and will not affect an existing pregnancy. TAKE ACTION will not protect you from HIV infection (the virus that causes AIDS) and other sexually transmitted diseases (STDs).

When should I use TAKE ACTION?

The sooner you take emergency contraception, the better it works. You should use TAKE ACTION within 72 hours (3 days) after you have had unprotected sex.

TAKE ACTION is a backup or emergency method of birth control you can use when:

  • your regular birth control was used incorrectly or failed
  • you did not use any birth control method

When not to use TAKE ACTION?

TAKE ACTION should not be used:

  • as a regular birth control method, because it’s not as effective as regular birth control.
  • if you are already pregnant because it will not work.
  • if you are allergic to levonorgestrel or any other ingredients in TAKE ACTION

When should I talk to a doctor or pharmacist?

Ask a doctor or pharmacist before use if you are taking efavirenz (HIV medication) or rifampin (tuberculosis treatment) or medication for seizures (epilepsy). These medications may reduce the effectiveness of TAKE ACTION and increase your chance of becoming pregnant. Your doctor may prescribe another form of emergency contraception that may not be affected by these medications.

How does TAKE ACTION work?

TAKE ACTION is one tablet with levonorgestrel, a hormone that has been used in many birth control pills for several decades. TAKE ACTION contains a higher dose of levonorgestrel than birth control pills, but works in a similar way to prevent pregnancy. It works mainly by stopping the release of an egg from the ovary. It is possible that TAKE ACTION may also work by preventing fertilization of an egg (the uniting of sperm with the egg) or by preventing attachment (implantation) to the uterus (womb).

How can I get the best results from TAKE ACTION?

You have 72 hours (3 days) to try to prevent pregnancy after unprotected sex. The sooner you take TAKE ACTION, the better it works.

How effective is TAKE ACTION?

If TAKE ACTION is taken as directed, it can significantly decrease the chance that you will get pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant.

How will I know if TAKE ACTION worked?

You will know TAKE ACTION has been effective when you get your next period, which should come at the expected time, or within a week of the expected time. If your period is delayed beyond 1 week, it is possible you may be pregnant. You should get a pregnancy test and follow up with your healthcare professional.

Will I experience any side effects?
  • some women may have changes in their periods, such as a period that is heavier or lighter or a period that is early or late. If your period is more than a week late, you may be pregnant.
  • if you have severe abdominal pain, you may have an ectopic pregnancy, and should get immediate medical attention. 
  • when used as directed, TAKE ACTION is safe and effective. Side effects may include changes in your period, nausea, lower stomach (abdominal) pain, tiredness, headache, dizziness, and breast tenderness.
  • If you vomit within 2 hours of taking medication, call a healthcare professional to find out if you should repeat the dose.
