Can I sue the pharmacy or only the doctor?

Both may be liable depending on where the error occurred. A prescriber's bad order, a pharmacist's mis-fill, or a nurse's wrong administration can each support a claim.

What if I had a known allergy listed in my chart?

A documented allergy that was ignored is strong evidence of breach. Hospital systems are expected to flag and check known allergies before administration.

Are over-the-counter drug errors covered?

Yes, when prescribed, recommended, or administered by a healthcare provider in a way that breaches the standard of care.

What evidence is needed?

Prescription, pharmacy fill records, MAR (medication administration record), nursing notes, allergy list, and the full medical chart.

How long do I have to sue?

State limits typically run from one to three years from injury or discovery. Speak with a lawyer promptly.

Direct answer

A medication error claim arises when a prescriber, pharmacist, nurse, or hospital administers, prescribes, or dispenses the wrong drug, dose, or combination, and the error causes patient harm. Liability often spans multiple providers and may include pharmacy and hospital systems.

Overview

Medication errors occur at every step of the medication chain — prescribing, transcribing, dispensing, administration, and monitoring. Even a single decimal-point error on a pediatric dose, or a missed drug-allergy alert, can cause catastrophic harm.

Because multiple providers and systems touch a single prescription, these cases often involve more than one defendant: the prescribing physician, the pharmacy, the dispensing pharmacist, the administering nurse, and the hospital or long-term care facility.
