For the second time this year (and the third time since September), birth control pills are being recalled over a packaging error that could cause the medication to be taken incorrectly. In February, Pfizer pulled several lots of birth control packs and last year, Qualitest Pharmaceuticals also had a packaging issue leading to a recall.

The latest problem? Seven lots of Nogestimate and Ethinyl Estradiol Tablets USP, 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg, manufactured by Glenmark Generics.

“The recall is being implemented because of a packaging error, where select blisters were rotated 180 degrees within the card, reversing the weekly tablet orientation and making the lot number and expiry date visible only on the outer pouch,” wrote the company.

Although the error does not pose any immediate health risks to women using the medication, it could place them at risk for unintended pregnancy. Those who think they might be using one of the affected packages should begin using a nonhormonal form of contraception immediately. They are advised to notify their physician and return the product to the pharmacy.
