I often get inquiries from patients about whether they can have children after taking the emergency contraceptive pill. I will quote from the U.S. Emergency Contraceptive Pill Guidelines to support my answer. The U.S. Food and Drug Administration (FDA) has resolved that although patients no longer need a doctor’s prescription to purchase the emergency contraceptive pill, medical personnel still have an important role to play in promoting awareness and understanding of the pill among the female population. The main tasks of the medical staff are: (1) to explain the basic knowledge of the emergency contraceptive pill; (2) to prescribe it to women under 18 years of age; (3) to prescribe it to patients over 18 years of age who have medical insurance; and (4) to provide the emergency contraceptive pill to patients at their place of practice. I. Emergency Contraceptive Pill The emergency contraceptive pill (ECP) is a safe and effective method to prevent pregnancy in cases where contraception has failed, such as unprotected sex, rape, condom breakage, or missed doses of contraceptive medication. The ECP is taken orally in 2 doses, the first within 72 hours of unprotected sex, followed by a second pill taken 12 hours apart. Recent studies suggest that when taking this monophasic progestin emergency contraceptive pill, the two doses can be combined in one dose with the same effect and no increase in adverse effects. It has also been suggested that ECP is still effective when taken 120 hours after unprotected sex. However, ECP is most effective when taken within 12 hours after sex, so we recommend taking ECP as soon as possible after sex. Emergency Contraceptive Pill Plan: This product is composed of progestin, which is more effective than estrogen and progestin combination contraceptives, and is more likely to cause nausea and other uncomfortable symptoms. It can cause nausea and other uncomfortable symptoms. Each l tablet of Pl an Bm contains 0.75mg of levonorgestrel. Non-specific emergency contraceptive pills Available on the market: More than 2O conventional estrogen-progestin biphasic oral contraceptives and 1 progestin-monophasic oral contraceptive pill can be found on the market today. ECPs with progestin monophasic are 89% less likely to result in pregnancy after unprotected sex, and only 1% more likely to result in conception (compared to 8% for women not taking ECPs). In contrast, ECPs with biphasic estrogen and progestin reduce the chance of conception by 75% and the chance of conception after taking them is 2%. Mechanism of action of ECPs ECPs act as contraceptives by delaying or inhibiting ovulation, inhibiting fertilization, or preventing fertilization of the egg. ECP is different from mifepristone (also known as the “abortion pill”, formerly known as Ru-486). ECP is primarily intended to prevent pregnancy and is not effective in pregnant women. In the United States, mifepristone is primarily used medically to terminate pregnancy. Adverse reactions and contraindications to ECP Adverse reactions ① Nausea/vomiting: Some people may experience vomiting after taking this drug, which is more common with estrogen- and progestogen- biphasic ECP, and may be relieved by taking an antiemetic 1 hour before the first tablet of ECP. If severe vomiting occurs within I hour of the first pill, a second pill should be taken. If severe vomiting cannot be taken orally, the drug may be administered vaginally (placed higher in the vagina). Other adverse reactions: short-term fatigue, headache, drowsiness, breast pain, change of menstrual cycle, etc. There is no contraindication to take emergency contraceptive pills. Emergency contraceptive pills can be considered for those who are not suitable for long-term contraceptive pills due to certain underlying diseases, and monophasic ECP is a better choice because it does not contain estrogen. Those who have been diagnosed with pregnancy should avoid taking this drug, ECP will not terminate pregnancy and will not cause fetal malformation. When counseling patients, they should give supportive and objective advice and encourage them to voice their concerns and doubts. Medical staff should explain the potential adverse effects of ECP to women who intend to take it. Professional training of sales associates, including salespeople, during the promotion of ECP can make the drug more acceptable to women. There is no need for a pelvic exam or pregnancy test before taking the drug, and there is no need for a hospital visit. Medical staff can instruct the patient by telephone on the use of the medication. During the telephone instruction, the patient’s menstrual history and the duration of unprotected sex should be taken to make a preliminary assessment of pregnancy. Other hormonal contraceptives may be taken at any time after taking ECP, and instrumental contraception may be used until the next menstrual period. If menstruation does not occur after 3 weeks of ECP, pregnancy-related tests should be performed. V. Emergency Contraceptive Pill Distribution Health care providers need to be aware that sometimes a woman who comes in to purchase contraceptives may be a victim of rape and should know how to appropriately interview, provide compassionate care, and offer counseling assistance and follow-up. We should provide emergency contraception to women who have been raped to prevent them from becoming pregnant. Pharmacies and clinics can provide Plan B without a prescription when a health professional is present. Physicians can prescribe Plan B or oral contraceptives directly to patients in the hospital. Studies have shown that if emergency contraception is prescribed in advance, people take it when they need it.
