Over 100 plaintiffs are named in a lawsuit seeking millions of dollars in damages from a pharmaceutical company, over a birth control packaging error that they say resulted in unplanned and unwanted pregnancies.

Plaintiffs from over 20 states are part of the lawsuit filed in the Philadelphia Court of Common Pleas last week.

The suit accuses Qualitest, Inc., a subsidiary of Endo Pharmaceuticals Inc., of issuing birth control pill packages in which the pills were rotated, allowing the women to mistakenly take the placebo sugar pill, instead of the birth control pills, at a time of the month when they could become pregnant.
