It is effective only in the first few days after intercourse. The emergency contraceptive pill cannot interrupt an established pregnancy or harm a developing embryo.
There are two methods: the emergency contraceptive pill and copper intrauterine device (IUD). Pill dose: 1.5 mg of Levonorgestrel to be taken within 72 hours (3 days) after intercourse or ulipristal acetate 30 mg, with single dose within 120 hours (5 days) after intercourse. The copper IUD should be taken if it had passed five days after intercourse.
Changes in menstrual bleeding, fatigue, headache, nausea and vomiting.
If vomiting occurs within 3 hours after taking the medication it is necessary to treat vomiting first and then repeat the treatment.
The next menstrual cycle may start before or after the time expected and the menstrual flow may be heavier or lighter than usual. Most women begin next period within 7 days of the expected date. If the menstrual period does not start within 3 weeks after taking the emergency pill then it is necessary to make a pregnancy test.
