Preven is used for preventing pregnancy. Preven is a combination birth control pill. It works by preventing ovulation, altering the cervical mucus, and changing the lining of the uterus.


Use Preven as directed by your doctor.
Take Preven by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
Begin taking Preven on the first Sunday following the start of your period, unless otherwise directed by your doctor. If your period begins on a Sunday, begin taking Preven on that day. Try to take Preven at the same time every day, not more than 24 hours apart. After taking the last pill in the pack, start taking the first pill from a new pack the very next day.
For Preven to be effective it must be taken every day. Do not skip doses.
If you miss a dose of Preven and remember it on the same day, take it as soon as possible and go back to your regular dosing schedule. If you do not remember until the next day or if you miss more than 1 dose of Preven, contact your doctor for further instructions. You may need to use an extra form of birth control (eg, condoms). If you are not sure about how to handle missed doses of Preven, use an extra form of birth control (eg, condoms) until you talk with your doctor.

Ask your health care provider any questions you may have about how to use Preven.


Store Preven at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Preven out of the reach of children and away from pets.
