More than 1 million packets of birth control pills are being recalled after packages were made with the incorrect dosage of active and inactive tablets. The pills themselves are not dangerous, but taking the incorrect dosage could lead to unwanted pregnancies. The affected drugs include Lo/Ovral-28 tablets and generic Norgestrel and Ethinyl Estradiol tablets that have expiration dates ranging between July 31, 2013, and March 31, 2014.

The drugs in question are manufactured by Pfizer, which already had a bad day on Tuesday, following a disappointing earnings announcement. The company beat income expectations, but announced a drop in both profit and revenue over 2010 numbers and revised the rest of its 2012 earnings downward. The patent on its most popular and lucrative drug, the cholesterol-fighting Lipitor, expired in November, causing sales to fall 42 percent in the United States in just one month.

The pills may also be labeled under the Akrimax Rx Products and Akrimax Pharmaceuticals brand, the company that markets the pills on behalf of Pfizer.
