GENERIC PLAN B® - LEVONORGESTREL 0.75MG - 2'S

The Morning After Emergency Contraceptive pill.

Levonorgestrel is a form of progesterone, which is a female hormone involved in conception. Levonorgestrel is used to prevent pregnancy by inhibiting ovulation (the release of an egg from an ovary) and by causing the cervical mucous to thicken, which makes it harder for sperm to move toward the uterus.

As a general rule, emergency contraceptive pills are taken in two doses. Take the first dose as soon as possible (up to 120 hours after you have sex without using birth control, your birth control failed, or you were forced to have sex. Take the second dose 12 hours later (although being an hour or two early or late probably won’t make a difference in how effective the pills are). You have the option of taking both doses at the same time. Keep in mind that emergency contraceptive pills are most effective the sooner they are taken after sex. Emergency contraceptive pills have no long-term or serious side effects, and it is safe for almost every woman to use them.
