Teva Canada Ltd. is recalling one lot of Seasonique prescription birth control due to the possibility of having an extra row of yellow pills in tray 1 and/or 2 of the blister cards, where there should be none. This may increase the risk of pregnancy. When packaged correctly, as shown in the picture, Seasonique pills come in extended-cycle tablet dispensers, each containing a 13-week (91-day) supply of pills divided in three blister cards: Tray 1 and Tray 2 each contain a blister card with 28 blue-green tablets (levonorgestrel and ethinyl estradiol) Tray 3 contains a blister card with 35 tablets: 28 blue-green tablets (levonorgestrel and ethinyl estradiol) and 7 yellow tablets (ethinyl estradiol) Users can expect to have four periods a year, with bleeding occurring while taking the yellow pills. Seasonique should be taken daily unless otherwise directed by your prescriber. Taking the pills in the proper order, according to the product instructions, is important for preventing pregnancy. Taking the wrong pill or a pill out of order could lead to an unplanned pregnancy or other side effects, including spotting and irregular bleeding. Health Canada is monitoring the company's recall and investigation, including its implementation of corrective and preventative actions. The Department will inform the public if any new health risks are identified.
