Oral contraceptive (levonorgestrel) NorLevo® has been released for prescription in Japan on April 2016. It is better known as Plan B (morning after pill) in the United States. This is a single pill you take by mouth. It must be taken within 72 hours (3 days) after unprotected sex or birth control failure to help prevent pregnancy. The sooner you take it, the better it will work for you.
When used as directed, oral contraceptives are generally safe and effective. But it shouldn’t be used as regular birth control, because it’s not as effective. Some may experience side effects, such as: Nausea, Abdominal cramps, Fatigue, Headache, Dizziness, Breast tenderness, Vomiting, and a period that is lighter, heavier, early, or late. It is contraindicated during pregnancy as the indication is for emergency contraception only. This pill will not protect you against HIV/AIDS or other sexually transmitted infections (STIs).
You will know it worked when you get your next period, which should come at the expected time. If your period is more than a week late, it is possible you may be pregnant. You should get a pregnancy test and follow up with your doctor. If you have any questions, feel free to call us at 03-6441-0969 and talk with one of our nurses.
