Many product liability claims arise out of the use of pharmaceutical drugs with dangerous side effects. Often, patients claim that those side effects were unreasonably dangerous or that the manufacturer, pharmacy, or doctor did not warn the patient of those side effects. But keep in mind that many drugs are known to carry serious risks. If your doctor properly advises you of those risks and you decide the risks are worth taking, you won't have a legal claim even if you suffer serious side effects.
Many pharmaceutical drugs have been the subject of class action lawsuits -- where numerous plaintiffs band together and file one lawsuit.
