Over the counter contraception

Emergency contraception (morning after pill) is most effective when taken within 12-24 hours after unprotected sex. 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. For the best chance for it to work, you should take the emergency pill as soon as possible.

Yes, you can use the emergency pill if something has gone wrong with your usual form of contraception, for example a forgotten pill (only if the intake is more than 48 hours ago) or split condom.

Repeated administration within a menstrual cycle is not advisable because of the possibility of disturbance of the cycle and a very high hormone dose. The emergency pill (morning after pill) should not be relied on as a regular form of contraception, and it is not as effective as other forms of hormonal contraception specifically made for regular use - it is only intended as a back-up.

No. Emergency contraceptives (morning after pill) do not work if a woman is already pregnant. When taken before a woman has ovulated, emergency pills prevent the release of an egg from the ovary or delay its release by 5 to 7 days. By then, any sperm in the woman\'s reproductive tract will have died, since sperm can survive there for only about 6 days.

No. Nearly all other contraceptive methods are more effective in preventing pregnancy. A woman who uses emergency contraceptives (ECPs) regularly for contraception is more likely to have an unintended pregnancy than a woman who uses another contraceptive regularly. Still, women using other methods of contraception should know about ECPs and how to obtain them if needed—for example, if a condom breaks or a woman misses 3 or more combined oral contraceptive pills.
