The "Morning After Pill " (Levonorgestrel, or Plan B)

Approximate effectiveness in preventing pregnancy: 95% when used as directed

No protection against STDs

MAY be made ineffective by antibiotic use. May react with other medications; consult your doctor or pharmacist if you are taking antibiotics. There is disagreement on this possibility.

If a condom breaks or unexpected sexual intercourse happens, a woman can consider using the "Morning After Pill". It works best if taken the day after intercourse but can be effective if taken up to three days after. It will have no effect on a pregnancy if it has already occurred. The Morning After pill can be gotten from a clinic, doctor, or, in Canada, many pharmacists. It is kept behind the counter. Pharmacists will be required to offer counseling about side-effects such as nausea and vomiting, sexually transmitted diseases and contraception to women who request the pills.

It works by giving the woman a high dose of hormones which stop the egg from becoming fertilised, or by making the uterus' lining unable to hold a fertilised egg. The Morning After Pill should be considered an "emergency" measure as the side effects are nausea and vomiting. There may be other side effects which the doctor or pharmacist can tell you about. At the time of writing, two pills are taken at first, then another two are taken twelve hours later.

The Morning After pill is a pill that prevents pregnancy going beyond fertilisation of the egg, if fertilisation even occurs. It should not be confused with the controversial drug RU486, which is not approved for use in Canada

A Parent, old geezer, and occasionally right. Good judgment comes from bad
experience, and a lot of that comes from bad judgment.

Yes, don't spend 400 dollars on the MA pill though, go to a walmart and buy plan B, it's a cheaper EC, it's only 60 dollars, and 89% accurate.

i was just wondering, if you have protected sex and the next morning, you think that the condom popped or something and there is a chance of unintended pregnancy, can you still take the Emergency Contraceptive
