The emergency contraceptive pill (after pill) can prevent pregnancy if taken within 72 hours of having unprotected sexual intercourse, such as contraception failure (condoms break or come off), or if you have been sexually assaulted. The chance of preventing a pregnancy is not 100%, but the earlier you take it, the higher the chance of stopping it.
The stopping rate is 95% when taken in the first 24 hours after sex, 85% between 25-48 hours and 58% between 49-72 hours. The medication we prescribe is 1.5 mg in Norlevo tablets or 1.5 mg in Levonorgestrel tablets (corresponding to the LNG group shown below).
In order to ensure that you take your medication as soon as possible, we have decided to make an appointment on the Internet as well.
If there are no openings in the appointment slots, please call us for an appointment. The doctor will explain and you can take the medication in the clinic as soon as possible.
You can also start the contraceptive pills for continuous contraception once you are sure that your next period has arrived. Please consult with us when you come to the clinic. Please see the price list for the cost (medication and initial consultation fee will be required).
