Pfizer recalls 28 lots of branded, generic oral contraceptive

NEW YORK — A possible pill mix-up has prompted Pfizer to recall more than two dozen lots of a prescription contraceptive drug, the drug maker said.

Pfizer announced the voluntary nationwide recall of 14 lots of Lo/Ovral-28 (norgestrel and ethinyl estradiol) tablets and 14 additional lots of the drug's generic version. Pfizer manufactured and packaged the drugs, while Akrimax Pharmaceuticals commercialized them, and they were sold under the Akrimax brand.

The company said an investigation found that some blister packs of the drugs may contain an inexact count of inert or active ingredient tablets and that the tablets may not be in the correct sequence. The packaging error could leave women without adequate contraception and put them at risk of unintended pregnancy, the company said.
