Postcoital Contraception, often known as the "morning after pill," is a safe and effective method of preventing pregnancy. It consists of a relatively high dose of one of several hormones that must be taken within 72 hours (ideally, within 24 hours unless otherwise specified) after unprotected intercourse, which may occur, for example, by dislodgement of the cervical cap or sponge or a condom breaking or slipping off. If taken as directed, postcoital contraception is 95% effective. It is as safe as taking 4 birth control pills at the same time; this is low risk for healthy women.
Directions for taking birth control pills postcoitally
You will receive one full packet of birth control pills at the pharmacy or receive pills from your practitioner. Your clinician will presribe the brand of your pill you should have. Do not take any birth control pills you happen to have around; they may not work.
Take, 1, 2 (or 4) pills immediately, then 1, 2 (or 4) pills 12 hours later. The number of pills depends on the brand used. Your practitioner will instruct you. These pills may cause nausea; if you eat first and take the pill(s) with a full glass of water and avoid alcohol, you can prevent nausea from occurring. If it does occur, take over-the-counter antacids like TUMS or Maalox. If you vomit a dose within an hour of taking it, repeat the dose and notify your provider as a second dose will need another prescription or refill order.
Possible Side Effects You May Experience
Aside from nausea (discussed above), you may experience vaginal bleeding, which may occur within hours of taking the pills or over the next week. If you have unusual cramping, fever, or more flow than usual, seek medical attention to determine the cause.
Delay in your regular period. Your period should arrive within 4-6 weeks after taking the pill. Regardless of whether you do or do not get your period, you should have a pregnancy test to be sure the postcoital contraception was effective. Getting a "normal period" is not sufficient proof (you can get your period and be pregnant). A first morning urine test or blood pregnancy test should be done to be sure. In some settings, the use of "morning-after" as routine birth control may not be considered an appropriate, safe, or responsible practice.
The risks of the "morning-after pill" are the same as for birth control pills.
Call for an appointment with SHS ext. 5050- the protocol requires a negative urine pregnancy test prior to prescription.
