Health Canada is following Europe's lead and will include a warning on the "morning after pill" stating the emergency contraception may not be as effective for women who weigh more than 165 lbs.

The pill can be taken to prevent pregnancy up to 72 hours after a woman has unprotected sex or a contraceptive accident. It contains a higher dose of levonorgestrel than regular birth control pills.

The "morning after pill" doesn't work if a woman is already pregnant.

Health Canada says companies that produce the medication will warn of reduced efficacy in women weighing 165-176 lbs. and that it's not effective for women who weigh more than 176 lbs.

The warning says women who weigh more than 165 lbs. should consult a doctor or pharmacist for alternatives.

The warning will be included in packaging in the next several months.

Europe started issuing the warning in late 2013.
