Morning After Pill (Plan B)
For more detailed information see Emergency Contraception
Emergency Contraception (EC) consists of taking a large dose of oral contraceptive (hormonal) medication.
EC is believed to act principally by preventing ovulation or fertilization. In addition it may act as an abortifacient by inhibiting implantation of a pregnancy. EC is not believed to be effective once implantation has taken place.
There are dozens of manufacturers of Emergency Contraception Medication. Side effects include queasiness and some women throw up after taking emergency contraception pills. You may also experience a headache, feel tired or dizzy, have some lower abdominal pain, or find your breasts are more tender than usual. Note: In a study of Plan B, a common hormonal emergency contraceptive, about 20% of women experience headaches, 13-14% experience painful menstruation, and 11-12% experienced nausea.
Things to Consider

- The manufacturers warn that Emergency Contraception is not meant for routine use as a contraceptive.
