Levonorgestrel (Generic Plan B)
The Morning After Emergency Contraceptive pill.
Levonorgestrel (Generic Plan B®) is a synthetic hormone, a second-generation progestin, used in birth control pills for over 35 years called emergency contraceptive pills, post-coital pills, or morning after pills. This is in the form of two levonorgestrel pills (0.75 mg in each pill) that are taken by mouth after unprotected sex. FDA has approved two products for prescription use for emergency contraception – Preven (approved in 1998) and Plan B (approved in 1999). This is the only product specifically approved and marketed in USA as an emergency contraceptive pill.
