Teva Canada Ltd. is recalling two lots of Seasonique and one lot of Seasonale prescription birth control pills, as a precautionary measure, after receiving a complaint that a Seasonique package was missing an entire blister card of pills. This may increase the risk of unwanted pregnancy if someone were to miss taking them. If your package is missing a blister card or any pills, it is important that you do not skip any doses or stop taking your medication and that you get a replacement or an alternative product as soon as possible. Seasonique and Seasonale should be taken daily unless otherwise directed by your prescriber. Taking the pills in the proper order, according to the product label, is important for preventing pregnancy. Missing a pill could lead to unwanted pregnancy and other side effects, including spotting and irregular bleeding. Seasonique Seasonique pills are packaged in extended-cycle pill dispensers, each containing a 13-week (91 day) supply divided into three blister cards, each placed on its own tray: Trays 1 and 2 each contain a blister card with 28 active light blue-green pills (levonorgestrel and ethinyl estradiol). Tray 3 contains a blister card with 35 pills: 28 active light blue-green pills (levonorgestrel and ethinyl estradiol) and 7 active yellow pills (ethinyl estradiol). Users can expect to have four periods per year, with bleeding occurring while taking the yellow pills. Seasonale Seasonale pills are packaged in extended-cycle pill dispensers, each containing a 13-week (91-day) supply divided into three blister cards, each placed on its own tray: Trays 1 and 2 each contain a blister card with 28 active pink pills (levonorgestrel and ethinyl estradiol). Tray 3 contains a blister card with 35 pills: 28 active pink pills (levonorgestrel and ethinyl estradiol) and 7 placebo white pills. Users can expect to have four periods per year, with bleeding occurring while taking the white pills. Health Canada is monitoring the company's recall and investigation, including its implementation of corrective and preventive actions. The Department will inform the public if any new health risks are identified.
