Efficacy & effects

Emergency contraceptive effect

View approved original text

Emergency contraceptives are used to prevent pregnancy when taken within 72 hours after unprotected intercourse or contraceptive failure. The sooner this medication is taken after intercourse, the more effective it is in significantly reducing the risk of pregnancy. Emergency contraceptives quickly lower the possibility of pregnancy in urgent situations, making them very useful for sudden circumstances. However, they should not replace regular contraceptive methods, and consulting a professional is advisable if needed. This medication is used effectively for preventing pregnancy.

How to take

Adult dose

Take 1.5 mg of Levonorgestrel orally once. The sooner you take it after intercourse, the more effective it will be. After unprotected intercourse, this medication should be taken as soon as possible (recommended within 12 hours), and no later than 72 hours (3 days) after. If vomiting occurs within 3 hours of taking it, another 1.5 mg of Levonorgestrel should be taken immediately.

Precautions

This medication is intended for temporary use as an emergency contraceptive and should not replace regular contraceptive methods. Taking this medication does not guarantee the prevention of all pregnancies, so if your menstrual period is more than 5 days delayed or if you experience abnormal bleeding or pregnancy symptoms, you should take a pregnancy test. People who are allergic to this medication, pregnant or potentially pregnant women, those with severe liver disease, or individuals with specific genetic issues such as lactose intolerance should not take this medication. People with a history of ectopic pregnancy or those at risk of ectopic pregnancy, such as those with salpingitis or pelvic inflammatory disease, and individuals with severe digestive disorders like Crohn's disease, or those with heart or kidney disease or a past medical history should use this medication with caution. Side effects may include dizziness, headache, nausea, abdominal pain, diarrhea, breast tenderness, delayed menstruation or bleeding, fatigue, and most of these symptoms will disappear within 48 hours. In some patients, serious side effects such as skin allergic reactions or thrombosis have been reported, so caution is needed. This medication should only be used once within a single menstrual cycle, and if there is uncertainty about the timing of intercourse or if used multiple times, its effectiveness may be reduced. After taking this medication, you must use non-hormonal contraceptive methods such as condoms or spermicides until your next period starts. If more than 72 hours has passed after intercourse, this medication will not be effective, so do not take it afterward. If there is subsequent intercourse after taking this medication, you should be aware of the possibility of pregnancy. Menstruation usually starts on the scheduled date after taking this medication, but it can be advanced or delayed by about 3 days, and if abnormal bleeding or delayed menstruation occurs, a pregnancy test should be taken. This medication may increase the risk of thrombosis, so individuals with a history of thrombosis or family history should be particularly cautious. This medication does not prevent sexually transmitted infections, so separate measures are needed to prevent STIs. It is advisable to consult a doctor when transitioning to regular contraceptive methods, and if there is no menstruation after taking this medication and starting contraceptive pills, pregnancy should be considered. Using this medication multiple times in a single menstrual cycle can burden the body, so it is advisable to consult about long-term contraceptive methods. This medication may be less effective when taken with certain liver enzyme inducers, so if you are taking liver enzyme inducers, consider other non-hormonal contraceptive methods. This medication should not be used during pregnancy, and caution is needed as taking it during pregnancy may affect the fetus. If you are breastfeeding, it is recommended to breastfeed before taking this medication and to avoid breastfeeding for at least 8 hours after taking it. Serious side effects from overdose are rare, but symptoms such as nausea or bleeding may occur and should be treated appropriately based on symptoms. This medication should be stored in a tightly sealed container away from direct sunlight and kept out of reach of children to maintain its quality.
