Plan B is an emergency contraceptive and does not require a prescription in Canada.
This product can only be shipped within Canada. It is recommended to keep a pack of Plan B in case your primary birth control method fails, because no birth control method is 100% effective.
Plan B contains only progesterone, in contrast with the traditional morning after pill (which requires a prescription), which is a strong birth control pill containing both estrogen and progesterone. As with other emergency contraception, Plan B is a method available to give women a second chance to prevent a pregnancy after unprotected sex. It will not work if you are already pregnant, in other words it cannot interrupt a pregnancy or cause an abortion. An emergency contraceptive (EC) is not a substitute for regular contraception. Plan B may prevent pregnancy by temporarily stopping the release of an egg from a woman's ovary, or by preventing fertilization. It may also prevent a fertilized egg from attaching to the uterus.
Each Plan B packet includes a single course of treatment and consists of two tablets, each containing 0.75 mg levonorgestrel (a synthetic progestogen). The first tablet should be taken as soon as possible within 72 hours (3 days) of unprotected intercourse. The second tablet must be taken 12 hours later.
The World Health Organization study demonstrated that after a single act of unprotected sex, Plan B prevented 89% of expected pregnancies if taken within 72 hours. When used within 24 hours Plan B prevented 95% of expected pregnancies.

- Plan B is not a substitute for regular contraception and does not work as well as using a preventive method of contraception.
