The Morning After Pill

The morning-after pill is a type of emergency birth control used to prevent pregnancy. It is intended as a backup contraception only, not as a primary method of birth control. Please note: The morning-after pill will not terminate a pregnancy that has already implanted. It is not the same thing as RU-486 (the abortion pill), which is a drug that terminates a pregnancy that has already implanted in the uterus.

Focus Women’s Center does not provide the morning-after pill, but if you think you may already be pregnant, FWC can provide you with free pregnancy testing once you have missed your period.

Types: There are two types of morning-after pills. One is available over-the-counter and contains levonorgestrel (such as Plan B One-Stop, Aftera, Take Action, My Way, etc). Levonorgestrel needs to be taken within 72 hours (3 days) of having unprotected sex. The other, ulipristal acetate (ella), is available only with a prescription, but it can be taken up to 120 hours (5 days) after having unprotected sex.

How They Work: Morning-after pills work mainly by delaying or preventing ovulation. The morning-after pill does not end a pregnancy that has already implanted in the uterine lining. However, it can prevent an already fertilized egg from implanting.

Effectiveness: Although it is called the “morning-after pill”, it is actually more effective the sooner you take it. If you take levonorgestrel within 72 hours (3 days) after having unprotected sex, it is 87% effective at preventing an implanted pregnancy. (2) There is some evidence that indicates that if you are overweight, the morning-after pill might not be as effective in preventing pregnancy. Also, using certain medications such as barbiturates or St. John’s wort, can decrease the effectiveness of the morning-after pill.

Side Effects: Morning-after pill side effects usually only last a few days and may include nausea, vomiting, dizziness, headache, tiredness, breast tenderness, lower abdominal pain or cramps, bleeding between periods, and a period that’s lighter, heavier, early, or late. Please note: If your period is more than a week late, it is possible that you might be pregnant. Focus Women’s Center can provide you with free pregnancy testing.

Risks: The morning-after pill does not provide lasting protection against pregnancy. It will not prevent you from getting pregnant if you have unprotected sex after taking it. The morning-after pill also does not protect against sexually transmitted diseases. If you are already pregnant, you should not take the morning-after pill.
