If you or a loved one suffered harmful side effects or complications from a prescription or over-the-counter medication, you may be entitled to financial compensation. At Benji Personal Injury, our California dangerous drug lawyers help victims hold negligent pharmaceutical companies, doctors, and pharmacies accountable.
A dangerous drug injury occurs when a medication causes unexpected harm that could have been prevented with proper design, manufacturing, prescribing, or warning labels. These injuries are often severe, sometimes permanent, and in the worst cases, fatal.
While most medications carry some risk, they are legally required to be reasonably safe when used as directed. When drug makers, healthcare professionals, or pharmacists fail in their duty to warn or protect consumers, the results can be catastrophic.
Drug injury cases fall under the umbrella of personal injury and product liability law, and often require investigation into pharmaceutical practices, FDA compliance, and patient history.
Dangerous drug injuries are not limited to one type of mistake. These cases often involve:
- Defective drug design: The drug is inherently unsafe, even when used correctly.
- Contamination during manufacturing: Unsafe particles or ingredients enter the drug during production.
- Lack of warning labels: Failure to disclose known risks or drug interactions.
- Misprescription: The doctor prescribes a drug inappropriate for the patient’s age, condition, or existing medications.
- Pharmacy error: Incorrect dosage, wrong medication, or mislabeled instructions.
- Overprescription: Prolonged or high-dose use that causes long-term damage.
In California, any one of these failures could form the basis of a personal injury claim.
Multiple parties may share legal liability for a drug-related injury, depending on where the breakdown occurred:
Pharmaceutical manufacturers
Drug companies are legally obligated to test their products rigorously and disclose side effects, risks, and interactions. If they fail to warn doctors and consumers—or suppress negative data—they can be sued for negligence or fraud.
Doctors and healthcare providers
A physician who fails to account for a patient’s allergies, medical history, or current medications before prescribing a drug may be liable for malpractice. Prescribing the wrong drug or dosage, especially in pediatric or elderly patients, can result in serious harm.
Pharmacies and pharmacists
Pharmacists must dispense the correct medication in the correct dose and flag any red flags regarding interactions or contraindications. If they overlook these, they may be held legally responsible for the resulting injury.
Drug marketers and distributors
In some cases, companies that market or distribute the drug can also be sued—particularly if they promoted off-label uses or omitted critical safety information.
Dangerous drug cases can involve a wide range of adverse effects, including:
- Organ damage (e.g., kidney or liver failure)
- Seizures or stroke
- Neurological conditions
- Heart attack or cardiac arrest
- Internal bleeding
- Severe allergic reactions
- Birth defects (when taken during pregnancy)
- Cancer or long-term diseases
- Death due to overdose or interaction
Even a minor mistake like an unlabeled side effect or misfiled prescription can lead to life-changing consequences. Our attorneys work with medical experts and investigators to determine how the injury occurred and who is responsible.
Dangerous drug lawsuits are not limited to class action lawsuits. Individuals can file personal injury claims when they’ve been harmed due to negligence or misconduct. These cases qualify because they involve:
- Negligence: A failure to take reasonable care during design, testing, prescribing, or dispensing.
- Causation: A direct link between the drug and the injury suffered.
- Damages: Real physical, emotional, or financial harm caused by the drug.
California law allows victims to pursue compensation for medical expenses, lost wages, pain and suffering, permanent disability, and more. In wrongful death cases, surviving family members may seek additional damages.
While any medication can become dangerous in the wrong circumstances, some drugs have been repeatedly linked to injuries:
- Opioids (OxyContin, Fentanyl, Vicodin) – addiction, overdose, death
- Antidepressants (Zoloft, Lexapro, Prozac) – suicidal ideation, birth defects
- Blood thinners (Xarelto, Pradaxa) – internal bleeding, strokes
- Diabetes medications (Invokana, Actos) – kidney failure, amputations
- Heartburn medications (Zantac) – cancer risks
- Birth control pills and IUDs – blood clots, hormonal disorders
- Cholesterol drugs (Lipitor, Crestor) – muscle damage, diabetes risk
Even over-the-counter drugs like Tylenol or ibuprofen can cause harm if improperly used or combined with other medications.
Victims of dangerous drugs may be entitled to compensation for:
- Medical bills: ER visits, hospital stays, surgery, long-term care
- Lost income: Wages lost during recovery or due to disability
- Loss of earning capacity: When injuries prevent future work
- Pain and suffering: Physical pain, emotional trauma, and loss of enjoyment
- Wrongful death damages: Funeral costs, loss of companionship, financial support
- Punitive damages: In cases of fraud or reckless conduct by a drug company

My doctor prescribed me a medication that caused a severe allergic reaction. Is this considered a personal injury case?
Yes, it could be. Doctors have a duty to review your medical history before prescribing medication. If your allergy was known or discoverable and your doctor failed to account for it, this may qualify as medical negligence. Our legal team can investigate whether the reaction was preventable and if you have grounds for a claim.
I was prescribed the wrong dosage and ended up in the ER. Is the pharmacy liable?
Possibly. Pharmacists must dispense the correct dosage exactly as written by the doctor. If the pharmacist misread the prescription or entered the wrong quantity, this could be considered pharmacy negligence. We regularly handle cases involving dosing errors that result in hospitalization or long-term harm.
I had no idea the drug I was taking had such serious side effects. There was no warning on the label. Can I sue the manufacturer?
Yes. Drug companies are legally required to warn about known risks, side effects, and interactions. If they failed to include clear warnings on packaging or in documentation—and you were harmed as a result you may have a product liability claim. These are common grounds for dangerous drug lawsuits.
I was prescribed a drug for years, and now I’ve developed a chronic illness. Can I still take legal action?
You may be able to. Long-term use of medications that were overprescribed or not adequately monitored by your doctor can lead to serious harm. If your provider failed to reassess or taper your medication over time, or if the drug itself was later found to be defective, you might qualify for a personal injury claim. Time limits apply, so it’s important to act quickly.
My elderly parent was given multiple medications that interacted badly. Who is responsible?
This could involve multiple parties. Doctors and pharmacists are both responsible for reviewing drug interactions especially with elderly patients who are at higher risk of complications. If your parent was harmed due to a failure to check for interactions, a claim could be made for medical malpractice or negligence.
What if the medication I took was recalled after I already suffered side effects?
A recall strengthens your case but isn’t required to file a claim. If you experienced injury before or even after a drug was officially recalled, you may still be eligible for compensation. A recall often indicates the manufacturer was aware of problems, which can be used as evidence of negligence.
I took an over-the-counter drug, not a prescription. Can I still sue?
Yes. Over-the-counter (OTC) drugs must meet the same safety standards as prescription drugs. If you took a medication as directed and were harmed due to a manufacturing defect, contamination, or lack of warning, you may have a viable personal injury claim.
What if I was injured but I can’t afford to go after a big pharmaceutical company?
At Benji Personal Injury, we handle dangerous drug cases on a contingency fee basis meaning you pay nothing unless we win. We also have the resources and experience to go up against large corporations and drug manufacturers on your behalf.
