What Is Plan B?
Plan B, also known as the "morning-after pill," is an emergency contraceptive meant to prevent pregnancy after unprotected sex. You don't have to wait until the morning to take it.
Effectiveness of Plan B
Plan B contains the hormone levonorgestrel, which is more effective the sooner you take it. It is not 100% guaranteed to prevent pregnancy.
Timing Is Crucial
The effectiveness of Plan B decreases as time passes. It is most effective within the first 24 hours after unprotected sex but can still work up to 72 hours later.
How to Use?
You can buy Plan B without a prescription or proof of age. However, it's not for routine contraceptive use. It's a one-dose regimen: You take one pill.
Who Should Avoid Plan B?
Don't use it if you are already pregnant, allergic to its ingredients, or experiencing abnormal vaginal bleeding. Ask the pharmacist or another health care provider if you are taking other medications.
Plan B vs. RU-486
Plan B is different from RU-486, which is used for medical abortions. Plan B prevents pregnancy, whereas RU-486 ends an existing pregnancy.
