Qualitest Pharmaceuticals, an Alabama pharmaceutical company, issued a voluntary national recall of 1.4 million packages of oral contraceptives on Friday due to what they called a packaging error.

A spokesman for Qualitest Pharmaceuticals stressed they are not worried about any health issues arising from it and the company said that it took drastic action because they are primarily concerned about unintended pregnancies after women took the oral contraceptive.

According to a statement from the company, select blisters (found inside the pill box) were rotated 180 degrees within the card, reversing the weekly tablet orientation. This helped to leave the pills' lot number, as well as the expiration date, no longer visible.

The recall affects Cyclafem 7/7/7, Cyclafem 1/35, Emoquette, Gildess FE 1.5/30, Gildess FE 1/20, Orsythia, Previfem and Tri-Previfem.

Birth-control pills, which contain estrogen and progesterone, prevent the release of an egg by fooling the body to believe it has already done so. The first three weeks of pills provide the hormones in varied or similar doses and the last four or seven pills of a pack, which are usually of a different color, contain nothing so that a woman can get her menstrual period.
