Medication Error Claims in the US
A medication error claim arises when a prescriber, pharmacist, nurse or facility gives, prescribes or dispenses the wrong drug or dose, or misses an allergy or dangerous interaction, and you are harmed. You must show a departure from the standard of care and that it caused your injury.
Where the Error Happened
A prescribing error, such as the wrong drug, an excessive dose or ignoring a documented allergy, is typically a doctor or nurse practitioner's responsibility. A dispensing error, such as a wrong strength or mislabelled bottle, involves the pharmacy. An administration error, such as giving a medication to the wrong patient or at the wrong time, is generally a hospital or care facility issue. Failure to monitor high-risk drugs can also be a basis for a claim.
Proving a Claim
Direct Answer: You must show the professional or facility failed to meet the standard of care, that this caused a specific injury, and, in most states, support the claim with a qualified expert.
Keep the medication packaging and labels, photograph them, and get copies of prescriptions, pharmacy records and medical records. A pharmacist or physician expert typically reviews the records.
Drug Manufacturers
If the problem was the drug itself, rather than a mistake in its use, a product liability claim against the manufacturer may lie, for example for a defective design or inadequate warnings. Mass tort litigation has arisen from several drugs, so this is a distinct route from an individual malpractice claim.
