Eugene (KMTR) - One million women could be at risk of an unintended pregnancy.
Pfizer has recalled one-million birth control packs because of an error that mixed up the active, and inactive pills in the 28-day package.
Some packets were found to have too many pills with active ingredients while others were found to have too few.
The world's biggest drug maker is pulling 14-lots of the Lo-Ovral tablets and 14-lots of its generic counterpart, Norgestrel and Ethinyl Estradiol tablets of the pills.
Pfizer says consumers exposed to the incorrect packaging should begin using a non-hormonal form of contraception immediately.
The company says the problem is not related to safety. it just raises the risk of unintended pregnancy.
If you have any questions you should check with your pharmacist.
