Breach of warranty is the violation of an agreement between a seller and a buyer as to the condition, content, quality, or title of the item sold. Therefore, if you take a prescription drug and it results in illness, injury, or death, you may have legal grounds for compensation. If the drug company is deceptive as to the quality or condition of their product, they are to be held responsible for your medical costs, pain, and suffering. It is incumbent upon the drug company to let people know the adverse side effects, as well as the benefits, of their drug.
