Women taking the incorrectly packaged pill would not receive the proper amount of contraceptive, raising the possibility of an unplanned pregnancy.
In a recall notice distributed by Health Canada, Apotex Inc. said the product's 28-day blister packs should include 21 active birth-control pills plus seven placebo tablets that contain no drug.
Apotex said blister packs in the affected lot — LF01899A — may instead contain 14 placebo pills and 14 active contraceptive tablets.
Alysena 28 is sold in British Columbia, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, P.E.I. and Quebec.
