Plaintiff is a young woman who suffered from recurring headaches. Originally on the advice of her physician and for a period of seven years thereafter on her own, plaintiff periodically took APC Tablets for her headaches. This painkiller is marketed over the counter for sale to the general public. Plaintiff has lost both kidneys due to renal lesions caused by phenacetin, which is a major ingredient of the drug. Plaintiff's recovery was based on negligent formulation--phenacetin was an essentially useless ingredient and was addictive as well as kidney destroying--and on negligent failure to warn customers of phenacetin dangers or dosage levels to be used.
