COMING TO THE RESCUE
Emergency contraceptives are often called the morning after pill. They were invented for exactly that, the morning after the night before when something did not quite go to plan. Accidents happen in all walks of life and sex is no different. Emergency contraceptives (morning after pill) can offer you a second chance to prevent pregnancy after having had unprotected sex.
An emergency pill typically contains hormones that are similar to oral contraceptives, but are much higher dosed. It works mainly by stopping or delaying the ovaries from releasing an egg. It may also work by changing the lining of the womb that may prevent implantation of a fertilized egg. For the best chance for it to work, you should take the emergency pill as soon as possible after unprotected sex. Ideally you should take it up to 12 hours after you’ve had unprotected sex but if it’s taken more than 24 hours after unprotected sex, it’s already much less effective.
Emergency contraception is most effective when taken within 12-24 hours after unprotected sex. There are 2 types of emergency pills in the market: the emergency contraceptive pill containing levonorgestrel (LNG) and the emergency contraceptive pill containing ulipristal acetate (UPA). For the best chance for it to work, you should take the emergency pill as soon as possible. Efficacy changes over time: while it’s 95% effective within the first 24 hours after unprotected sex, that number drops to 58% when the pill is taken within 49-72 hours.
The levonorgestrel emergency contraceptive pill should not be used in the same menstrual cycle as ulipristal acetate. After using emergency contraception you should use another form of contraception for the rest of your cycle to protect yourself if you do not want to become pregnant.
