Contraceptives
Storage Instructions

Your oral contraceptives should be store in a dry place with a controlled temperature, away from any sources of moisture, light, pets, and children. You should also read the pamphlet in the package of your birth control for any specific instructions regarding temperature or humidity levels for storage.

Birth control can handle higher or lower temperatures for short periods but should not be exposed to temperatures below 59 F (15 C) or above 86 F (30 C) for an extended period of time. If you store it at a much hotter or colder temperature than that range, your pills theoretically could lose their potency. Since oral contraceptives are hormone-based, they can be affected by temperature fluctuation.

Description

Oral contraceptives are known also as the Pill, OCs, BCs, BC tablets, or birth control pills. This medicine usually contains two types of hormones, estrogens and progestins and, when taken properly, prevents pregnancy. It works by stopping a woman’s egg from fully developing each month. The egg can no longer accept a sperm and fertilization is prevented. Although oral contraceptives have other effects that help prevent a pregnancy from occurring, this is the main action.

 Sometimes a woman’s egg can still develop even though the medication is taken once each day, especially when more than 24 hours pass between two doses. In almost all cases when the medicine was taken properly and an egg develops, fertilization can still be stopped by oral contraceptives. This is because oral contraceptives also thicken cervical mucus at the opening of the uterus. This makes it hard for the partner’s sperm to reach the egg. In addition, oral contraceptives change the uterus lining just enough so that an egg will not stop in the uterus to develop. All of these effects make it difficult to become pregnant when properly taking an oral contraceptive.
