Pharmacology & Pharmacy Expert Witness

Pharmacology and pharmacy expert witnesses evaluate medication prescribing, dispensing, and administration practices to determine whether drug selection, dosing, interaction screening, and patient monitoring met the standard of care. They analyze prescription records, pharmacy dispensing logs, medication administration records, and adverse event timelines to identify where in the medication-use process errors occurred and whether they caused or contributed to patient harm.

Cases commonly requiring pharmacy expertise include wrong drug or wrong dose dispensing errors, failure to screen for dangerous drug interactions, look-alike/sound-alike medication mix-ups, compounding pharmacy contamination and sterility failures, and opioid overprescribing and diversion. These matters often involve multiple defendants—prescriber, pharmacist, and institution—requiring an expert who can delineate each party's duty and breach within the medication-use chain.

Subspecialty areas including clinical pharmacology, hospital pharmacy, oncology pharmacy, compounding, and pharmacovigilance and drug safety each involve different regulatory frameworks and practice standards. An expert with active practice or research in the relevant pharmaceutical area provides opinions that address both the clinical pharmacology and the systems-level failures that medication error litigation demands.
