The use of Pharmacists as expert witnesses in medical legal cases should be no surprise to anyone. Pharmacists would be expected to have the knowledge or expertise needed to decide the facts of many aspects of medicinal care. Were there any contradictions to using a specific pharmacologic agent? Were warnings ignored? Were other medications being used concurrently that could have interacted? Did the patient have side effects in the past with similar medications? Were the adverse effects reported related to the therapy prescribed? Were illicit substances used that could have provoked the idiosyncratic consequences?
