New warning coming with emergency contraceptive pills

April 1, 2014

Emergency contraceptive pills, also known as the “morning after” pill, will soon carry new warnings about reduced effectiveness in women weighing over 165 pounds.

Health Canada has asked companies to add new warnings to product packages advising that these pills are less effective in women weighing 165 to 176 pounds (75-80 kg), and are not effective in women over 176 pounds (80 kg). They are advising women who weigh 165 pounds (75kg) or more to talk to a health professional, such as a doctor or pharmacist, for advice on alternative methods of emergency contraception.
