Canadians who take birth control pills may want to check their medicine cabinet. Health Canada has issued a nationwide recall for one lot of Seasonique birth control due to missing pills. According to Health Canada, Seasonique pills are packaged in extended-cycle tablet dispensers, each containing a 13-week (91-day) supply of pills: 84 light blue-green tablets (levonorgestrel and ethinyl estradiol) followed by seven yellow pills (ethinyl estradiol). The recall says Seasonique should be taken daily unless otherwise directed by your prescriber, and that taking the birth control pills as instructed is important for preventing pregnancy. Health Canada says it's monitoring the company’s recall and investigation, including its implementation of corrective measures to prevent this issue from happening again.
