Pfizer Inc., the world's biggest drugmaker, recalled 1 million packs of birth-control pills after discovering a packaging error that may cause women to take the wrong dosages, putting them at risk for unintended pregnancies.
The company recalled 14 lots of Lo/Ovral-28 tablets and 14 lots of a generic version of the medicine, New York-based Pfizer said Tuesday in an email.
About 1 million packs of 28 tablets were withdrawn, Grace Ann Arnold, a Pfizer spokeswoman, said.
The tablets, manufactured and packaged by Pfizer, were marketed by Akrimax Rx Products of Cranford, N.J., under the Akrimax Pharmaceuticals brand. The company hasn't received any reports of adverse health consequences, Arnold said.
Each pack contains 21 white tablets that contain the synthetic hormones norgestrel and ethinyl estradiol and are taken for 21 consecutive days. The remaining seven tablets are inactive pink pills taken for a week.
"An investigation by Pfizer found that some blister packs may contain an inexact count of inert or active ingredient-tablets and that the tablets may be out of sequence," the company said.
That could cause women to take an incorrect daily dosage and increase the risk of accidental pregnancy.
