Aspen Pharmacare Canada Inc. is recalling one lot (lot 200049, expiry 03/2023) of Linessa 21, a prescription birth control pill, due to missing and mispackaged pills. Some blister packs may be missing pills, may contain more than one tablet in a blister pocket, and may contain pills in the wrong order. Linessa 21 packages contain 21 coloured pills: 7 light yellow, 7 orange and 7 red, with a different amount of hormone in each colour of pill. The pills are taken daily for three weeks, followed by one week of not taking pills (unless otherwise directed by the prescriber). Taking the pills in the proper order, according to the instructions that accompany the product, is important for preventing pregnancy. Missing a pill, taking a pill out of the proper order, or taking two pills at the same time could lead to undesired pregnancy and other side effects, including spotting and irregular bleeding. It is important to get a replacement package as soon as possible to avoid missing any pills or taking a pill in the wrong order. Health Canada will update the table below and inform Canadians if additional recalls are necessary.
