A Canadian drug distributor has issued an urgent warning for thousands of women taking its birth control pills after a manufacturing error means one batch contains too many placebos.

Apotex, which is based in Toronto, recalled packages of Alysena-28 with the code LF01899A as they may contain two weeks of placebo sugar pills instead of one.

The error, which affected thousands of boxes, can raise the possibility of an unplanned pregnancy as it leaves women unprotected by the contraceptive for a week during their cycle.

The rogue batch was distributed in all Canadian provinces except Saskatchewan and Alberta and was given to patients from December last year until the recall.

The company says that they do not distribute to the United States. But to make sure check that you do not have any of these pills in your current prescription. Especially if you have ordered from Canadian pharmacies online.
