If you decide to take the pill afterwards, you should act quickly. The sooner you take the tablet after unprotected intercourse, the higher the chances that an unwanted pregnancy can actually be prevented.
So it's best to do it right away, i. within 24 hours and at the latest within 72 hours, ie about 3 days thereafter. If the pill is taken within 24 hours of being on the road, it will be around 95% effective. After 48 hours, a maximum of 70% and after taking up to a maximum of 72 hours thereafter still about 50%.
All these data refer to the now usual and recommended variant of the pill thereafter with the active ingredient levonorgestrel (1.5 mg) in the preparation PiDaNa®, duofem® or Levogynon®. (Whether the pill is taken as one or two tablet dose of 0.75mg afterwards, by the way, does not matter in terms of the chances of success).
Even 3 days "after" a pregnancy can still be prevented
If the unprotected traffic is more than 3 days ago, in Germany with the so-called Progesterone receptor blocker Ulipristal 30mg (ellaOne®, 1 tablet) there is now another option to prevent pregnancy until the 5th day or 120 hours afterwards.
Alternatively, the so-called copper spiral is available for emergency contraception up to 5 days after traffic (see info under "Spiral").
By the way: Also due to the facts and experiences mentioned above, the term "morning-after-pill" (English for "morning-after-pill"), which used to be used internationally for quite some time, is now uncommon. Although the pill should actually be taken as soon as possible after circulation in case of need. However, this outdated designation suggests that there would only be a time window of a few hours in which to be active if necessary. That's just not true and that should - especially to avoid abortions - in this emergency also know.
