GENERIC AVAILABLE: Yes, for some (see below)
PREPARATIONS: Tablets, various amounts (Please see the birth control article for non-oral contraceptives.)
STORAGE: All oral contraceptives should be stored between 15 C (59 F) and 30 C (86 F).
PRESCRIBED FOR: Birth control pills are prescribed to prevent pregnancy. When taken as directed, birth control pills fail in less than one in every 200 users over the first year of use.
Birth control pills also are prescribed to treat mid-cycle pain, which some women experience with ovulation. Birth control pills, while regulating the menstrual cycle, reduce menstrual cramps and heavy bleeding, and because of the reduced bleeding, they may prevent the anemia that can develop in some women. For this reason, they also are sometimes prescribed for a number of conditions that are characterized by excessive bleeding or painful menses.
Doctors sometimes prescribe higher doses of birth control pills for use as a "morning after" pill to be taken up to 72 hours after unprotected intercourse to prevent fertilization and pregnancy.
DOSING: Many of the birth control pills come in easy-to-use dispensers in which the day of the week or a consecutive number (1, 2, 3, etc.) is written on the dispenser with a corresponding tablet for each day or number.
For example, some Ortho-Novum dispensers are labeled "Sunday" next to the first tablet. Thus, the first tablet is to be taken on the first Sunday after menstruation begins (the first Sunday following the first day of a woman's period). If her period begins on Sunday, the first tablet should be taken on that day.
For birth control pills that use consecutive numbers, the first tablet (#1) is taken on the first day of the menstrual period (the first day of bleeding). Tablet #2 is taken on the second day and so on.
Still other packages instruct women to begin on day five of the cycle. For such products, women count from day one of their menstrual cycle (day one is the first day of bleeding). On the fifth day, the first tablet is taken. Tablets then are taken daily.
Most birth control pills are packaged as 21-day or 28-day units. For 21-day packages, tablets are taken daily for 21 days. This is followed by a seven-day period during which no birth control pills are taken. Then the cycle repeats.
For the 28-day units, tablets containing medication are taken for 21 consecutive days, followed by a seven-day period during which placebo tablets (containing no medication) are taken.
