Health Canada has been informed by Apotex Inc. that the company will be recalling additional lots of Alysena-28 birth control pills as a precautionary measure while it investigates why one lot of the product contained packages with extra placebo pills in place of active pills. Packages of Alysena-28 should have three rows of pink (active) pills and only one row of white (placebo) pills. Alysena-21, which is manufactured at the same facility, is not part of the current recall as these packages don't normally include a row of the white (placebo) pills. However, because the product is made in the same facility, Health Canada and Apotex are working together to verify this product as well. In the meantime, Canadians are encouraged to check to make sure their packages of Alysena-21 contain three rows of pink pills. Health Canada is committed to protecting the health and safety of Canadians. The department will continue to monitor the situation and update Canadians and health care practitioners should new information be identified. The specific lots being recalled are: LF01901A LF01980A LF02037A LF01900A LF01982A LF02036A LF01898A LF01981A LF02026A LF01894B LF01979A
