One of the most basic responsibilities of a prescribing physician is to ensure that medications given to a patient are safe for their specific health condition. When a drug is contraindicated, it means that taking it poses a clear and serious risk. Contraindications may be absolute—meaning the drug should never be used under any circumstance—or relative, meaning the risks outweigh the benefits in certain conditions.
Unfortunately, cases of medical malpractice arise when healthcare providers fail to stop or discontinue contraindicated medications. A patient with a history of bleeding disorders may still be given blood thinners. Someone with kidney or liver impairment may continue receiving medications their body can no longer safely metabolize. Or a pregnant woman may be prescribed drugs known to cause birth defects. These errors are not minor—they are often catastrophic, preventable, and rooted in negligence.
Medication safety guidelines exist precisely to prevent contraindication errors. Physicians, pharmacists, and nurses all share responsibility for ensuring that no patient is given a medication that conflicts with their health status. Electronic prescribing systems and pharmacy databases include alerts for contraindications, but in busy medical environments, these warnings are often ignored or overridden.
The result is that patients may be exposed to serious risks that could have been entirely avoided had proper safeguards been followed. Contraindicated drug malpractice is particularly troubling because it involves decisions that go against established medical knowledge and standards of care.

The statistics are sobering. According to the Institute of Medicine, medication errors—including contraindication issues—harm at least 1.5 million Americans every year. A study published in JAMA Internal Medicine revealed that up to 20% of hospitalized patients are given at least one potentially inappropriate medication, many of which are contraindicated for their condition.
The FDA also reports thousands of adverse drug events each year tied to contraindicated medications. These events are likely underreported, meaning the true scope of the problem is far larger. Elderly patients, who often take multiple prescriptions at once, are particularly vulnerable. A contraindicated prescription in this population can easily trigger hospitalization or death.
While every case is unique, patterns emerge in how contraindication errors occur. One of the most common is failure to discontinue a drug after a patient develops a new medical condition. For instance, a patient may begin chemotherapy, which alters liver function, but doctors fail to stop other medications that can no longer be safely metabolized.
Another frequent scenario involves drug interactions. A physician may prescribe a new medication without considering how it interacts with drugs the patient is already taking. If those combinations are contraindicated, the result can be cardiac arrhythmias, strokes, or organ failure.
Pregnant and breastfeeding patients are also at risk. Contraindicated drugs in these populations can cause congenital disabilities, miscarriage, or harm to nursing infants. In each of these cases, the risk is well-documented, and safe alternatives are often available—making the decision to continue the medication especially negligent.
There are many underlying causes for these errors, but most stem from failures of diligence and communication. Doctors sometimes fail to thoroughly review patient histories before prescribing medications. In fast-paced hospital environments, test results showing liver or kidney impairment may be overlooked.
Pharmacies also bear responsibility. Pharmacists are trained to flag contraindications, but overworked staff may bypass software alerts or assume the prescribing physician has already made the necessary evaluation. Nurses administering medications may follow orders without questioning whether the drug is safe for the patient in their care.
Ultimately, these cases demonstrate systemic breakdowns where multiple opportunities to prevent harm are missed.
The standard of care requires that physicians and pharmacists:
When healthcare providers fail to meet these responsibilities, their negligence can form the basis of a malpractice claim.
The consequences of these errors vary depending on the medication and condition, but they are often severe. For patients with heart disease, receiving contraindicated medications may trigger arrhythmias, heart attacks, or strokes. For those with kidney or liver impairment, drugs can accumulate to toxic levels, leading to organ failure. Pregnant women given contraindicated drugs may suffer miscarriage or give birth to children with preventable congenital disabilities.
Other patients may experience internal bleeding, seizures, or life-threatening allergic reactions. In many cases, these injuries result in extended hospitalization, permanent disability, or wrongful death.
To establish malpractice, it must be shown that the healthcare provider knew—or should have known—that a drug was contraindicated for the patient, yet continued its use. Evidence often includes prescription records, lab results, medical charts, and expert testimony from pharmacologists and physicians. Attorneys must demonstrate both a breach of the standard of care and a direct link between the contraindicated medication and the harm suffered.
At Snyder & Wenner, P.C., we have seen firsthand the devastation caused by contraindicated medication errors. Our attorneys work with medical experts to investigate how the error occurred, identify the responsible parties, and fight to secure justice for victims and their families.
We understand that these cases are about more than financial recovery—they are about ensuring patients can trust their healthcare providers and preventing the same errors from harming others in the future. Our mission is to hold negligent doctors, pharmacists, and hospitals accountable for their actions.
Liability in these cases often extends beyond a single provider. The prescribing physician may be responsible for failing to discontinue the medication, but pharmacists can also be held accountable for filling prescriptions that they should have flagged as unsafe. Nurses and other healthcare professionals who administer medications without questioning contraindications may also share responsibility. Hospitals and healthcare organizations can be liable when systemic issues such as poor communication or unsafe staffing contribute to the error.
Victims of contraindicated drug malpractice may be entitled to compensation for a range of damages. These include the cost of emergency medical treatment, hospitalizations, and corrective care required after the error. Long-term medical expenses for organ failure, neurological damage, or other permanent injuries may also be recoverable.
In addition to medical costs, patients may claim lost wages and diminished earning potential. Pain, suffering, and emotional trauma are also significant damages in these cases. For families who lose a loved one due to contraindicated drug errors, wrongful death claims may provide compensation for funeral expenses, loss of companionship, and other profound losses.
Pharmacies are supposed to safeguard patients, not endanger them. Dispensing the wrong medication is never a “minor” error—it can cause irreversible harm. Patients and families deserve to know that when they walk into a pharmacy, their safety is protected.
At Snyder & Wenner, P.C., we fight for those harmed by pharmacy negligence. By holding pharmacies accountable, we not only secure justice for victims but also push the industry toward stronger safeguards, ensuring safer care for all patients.
