Medication Error FAQs

A medication error is a preventable drug mistake that causes or contributes to patient harm. It may involve prescribing the wrong medication, ordering an unsafe dose, overlooking an allergy or interaction, dispensing a different drug, administering medication to the wrong patient, using an improper method, or failing to monitor the patient. An overdose can cause respiratory distress, internal bleeding, organ damage, seizures, coma, or death. An underdose may allow an infection, blood clot, heart condition, or other illness to progress. Not every adverse reaction proves malpractice because complications can occur despite appropriate care. Determining whether an injury resulted from negligence requires comparing the treatment with accepted medical practice and evaluating whether the mistake caused additional harm.

Responsibility depends on where the failure occurred and each provider’s role. A prescriber may be liable for selecting an inappropriate drug, ordering the wrong dose, or overlooking known risks. A pharmacist may bear responsibility for dispensing the wrong medication, misreading an order, using an incorrect label, or failing to address a dangerous interaction when professional standards required action. Nurses may be liable for administering the wrong drug or dose, failing to verify the patient’s identity, or neglecting required monitoring. Hospitals, clinics, nursing homes, and pharmacies may also face liability for employee conduct or unsafe systems involving staffing, communication, training, electronic orders, or medication storage. Investigation is often necessary because several people or organizations may have contributed to the injury.

A patient generally must establish duty, breach, causation, and damages. Duty arises from the professional relationship and requires care consistent with accepted standards. Breach means that the provider departed from those standards. Causation requires proof that the departure was a substantial factor in producing an injury that otherwise would not have occurred. Damages are the resulting losses. Because medication decisions usually involve specialized knowledge, qualified experts commonly explain the standard of care, the violation, and how it caused harm. New York also generally requires the plaintiff’s attorney to consult a knowledgeable physician before filing a medical malpractice action and to submit a certificate of merit, subject to statutory exceptions. Recoverable damages may include medical expenses, lost earnings, reduced earning capacity, rehabilitation and personal-care costs, pain and suffering, and loss of enjoyment of life. Different damages may apply when an error causes death.

Relevant evidence may include prescriptions, electronic orders, pharmacy dispensing records, medication administration records, nursing notes, allergy lists, laboratory results, discharge instructions, drug containers, labels, receipts, and provider communications. These materials may show when a drug was ordered, who reviewed or changed it, what was dispensed, when it was administered, and whether providers responded to warning signs. Patients should preserve medication containers and instructions and obtain appropriate care for continuing symptoms. An attorney may request complete records, consult experts, compare medication histories, and investigate whether a hospital, pharmacy, or facility followed its safety procedures. Prompt investigation matters because memories fade, records may become difficult to locate, and identifying the point of failure can require information from several providers.

New York generally requires a medical malpractice action to be commenced within two years and six months of the challenged act or omission, or from the end of continuous treatment for the same illness, injury, or condition. The continuous-treatment rule is fact-specific and does not extend to every claim. Shorter deadlines and special notice requirements may apply when treatment was provided by a public hospital, municipal facility, or government-employed provider. Other exceptions may affect particular cases, but discovering an error later does not automatically restart the period. People harmed by medication errors should seek legal advice as soon as possible, even while treatment continues or the full injury remains uncertain. An attorney can determine the correct defendant, deadline, and procedural requirements from where the care occurred and the treatment relationship.
