Drug Facts
React ™
What is React ™?
React ™ 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 React ™ is not.
React ™ will not work if you are already pregnant and will not affect an existing pregnancy. React ™ will not protect you from HIV infection (the virus that causes AIDS) and other sexually transmitted diseases (STDs).
When should I use React ™?
The sooner you take emergency contraception, the better it works. You should use React ™ within 72 hours (3 days) after you have had unprotected sex.
React ™ 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 React ™.
React ™ 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 React ™.
How does React ™ work?
React ™ is one tablet with levonorgestrel, a hormone that has been used in many birth control pills for several decades. React ™ 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 React ™ 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 React ™?
You have 72 hours (3 days) to try to prevent pregnancy after birth control failure or unprotected sex. The sooner you take React ™, the better it works.
How effective is React ™?
If React ™ 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 React ™ worked?
You will know React ™ 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 period, 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, React ™ 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 the medication, call a healthcare professional to find out if you should repeat the dose.
