When taking properly, birth control pills are thought to be almost 100 percent effective. But if there is a mix-up in the drug sequences and combination of active and inactive drugs, well then, you might not have this nearly 100 percent effective rate.

The globe's largest drug maker, Pfizer, is recalling approximately one million packages of its Lo/Ovral-28 oral contraceptive, including its generic equivalent. But users can feel "a little" bit better knowing the company estimates that only a very small percentage of the one million packages were recalled. Pfizer estimates that just about 30 packets may be fraught with problems. Some pills were thought to have two many of the active variety of tablets, while other packages were believed to have too few of the active variety of tablets. Either way, the incorrect pill packages up the risk of pregnancy.

That said, women who take this particular oral contraceptive pill need to take other precautions if they want to avoid an unwanted pregnancy.

This particular oral contraceptive is a widely prescribed birth control pill. The pills were labeled under the brand Akrimax Pharmaceuticals and were distributed to pharmacies, retail outlets, clinics and warehouse throughout the nation.

Users who would like to see if their package of Lo/Ovral-28 was impacted, they can go to the FDA recall website. There they will find a detailed listing of the recall, including the LOT numbers affected.

If women who had the faulty oral contraceptive packets, Pfizer could see their share of product liability lawsuits for wrongful pregnancy.
