A pharmaceutical drug injury can be any injury caused by a prescription, or non-prescription drug (over-the-counter medicine).  The injury is usually one that requires immediate medical attention and is for a serious injury.  An example of this can be an ischemic stroke injury, or mitral valve prolapse of the heart which were two of the injuries San Diego Pharmaceutical Drug Injury Lawyer Mark C. Blane has handled over the years against defective pharmaceutical drugs.
