Plan B, the so-called “morning after pill” is marketed as a back- up birth-control method, similar to a heavy dose of the birth control pill, only it can be taken up to 72 hours after intercourse to prevent pregnancy. It prevents the release of an egg from the ovary and stop fertilization of an egg, but does not work if already pregnancy. If Plan B is not taking right it could end up having an adverse effect. If 17 or older Plan B is available without a prescription at a pharmacy counter. If under 17, you'll need a prescription from a doctor.
I think that Plan B is a good product for women because if a woman or teens thinks she might be pregnancy taking a Plan B would be safe and effective. Another reason why is because birth controls can fail and you need something to use that is also safe. That is why I think Plan B is a good choice.
