Health Canada says Apotex Inc. will be recalling 11 additional lots of Alysena-28 birth control pills as a precautionary measure. Apotex is making the additional recall while it investigates why one lot _ LF01899A _ of the product contained packages with extra placebo pills in place of active pills. Packages of Alysena-28 should have three rows of the pink active pills and only one row of white placebo pills. Canadians using this product should use a non-hormonal method of birth control, contact their health care provider for medical advice and return unopened packages to their pharmacist. 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 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.
