Understanding Prescription Drug Injury Litigation

Prescription medications are meant to improve health conditions and quality of life. But even with FDA approval, it is not uncommon for drugs to cause serious side effects. The consequences of defective drugs can be devastating, ranging from severe health complications to permanent disability or death. 

Pharmaceutical litigation is important not only to compensate those harmed by these products, but also to hold drug makers accountable for failing to adequately test products or warn of known or reasonably knowable risks.   

A pharmaceutical injury lawsuit typically involves:

  • Medications with undisclosed or underreported side effects.
  • Drugs that have not been adequately tested before market release.
  • Prescription drugs with insufficient warnings about potential risks.

For injured patients, a pharmaceutical lawsuit can help pay for medical bills, lost wages, and the pain experienced after taking the medication or receiving a procedure using a defective medical device. Beyond helping individual plaintiffs, pharmaceutical lawsuits help protect all consumers by pushing companies to be honest about their products. These cases often reveal that companies were aware of certain dangers but concealed them to continue generating profits. 

When pharmaceutical lawsuits are successful, they not only compensate victims but also compel drug manufacturers to enhance safety standards, update warning labels, and sometimes even remove defective products from the market altogether. 

What is a Pharmaceutical Drug Lawsuit?

Pharmaceutical drug lawsuits happen when the products cause unexpected harm and the companies that manufacture the products failed to warn about the potential harm. These lawsuits aim to compensate those harmed and hold companies accountable for their negligence or wrongdoing. 

To qualify for a drug injury lawsuit, you must have suffered verifiable harm after taking the medication or undergoing a procedure using a defective device. Your lawyer will need to show a clear connection between taking the drug or undergoing a procedure and your injury or side effects. 

Most of the time, these lawsuits are consolidated into a mass tort, which is similar to a class action in that many people harmed by the same product join together in front of one judge. The key difference between a mass tort and a class action is that each person's specific injuries and claims for damages differ in a mass tort, so each plaintiff is treated individually. In a class action, the group (“class”) is treated as a single entity with a representative plaintiff (or plaintiffs). 

The legal process for prescription drug lawsuits typically takes one to three years, although it can be longer or shorter depending on your case. 

Every state has a deadline called a "statute of limitations" for filing these lawsuits, ranging from one to six years after you discover your injury. If you miss this deadline, you may lose your right to seek compensation, so it is crucial to speak to a lawyer as soon as you can about your potential claim.

How a California Drug Injury Attorney Can Help

If you've been harmed by a prescription or over-the-counter medication, an experienced pharmaceutical lawyer can be your strongest advocate. 

Our attorneys will:

  • Evaluate the strength of your claim through a free consultation.
  • Gather crucial medical records and evidence to support your case.
  • Identify all potentially liable parties, from manufacturers to distributors to retailers.
  • Work with medical experts to establish causation between the product and your injuries.
  • Calculate the full extent of your damages, including future medical needs.
  • Negotiate with pharmaceutical companies for a fair settlement.
  • Prepare your case for trial if a fair settlement cannot be reached.

At Wisner Baum, our California pharmaceutical lawyers handle cases on a contingency fee basis, meaning you pay nothing unless we win your case. This allows anyone harmed by defective drugs to access quality legal representation regardless of their financial situation.

Current Lawsuits Against Pharmaceutical Companies 

Our pharmaceutical litigation attorneys are currently investigating and accepting cases involving several medications. If any of the following drugs have harmed you, our law firm can help determine if you have a viable claim.

Antipsychotics Lawsuit

Risperdal (risperidone), Invega (paliperidone), and Zyprexa (olanzapine) are antipsychotic medications linked to an increased risk of breast cancer. Our pharmaceutical lawyers were the first in the country to file a lawsuit alleging Johnson & Johnson and Eli Lilly failed to warn patients and the medical community about the link between antipsychotics and breast cancer, which we allege the companies knew since the 1990s.  

Learn more about Antipsychotics and Breast Cancer Lawsuits

Zantac Lawsuit

Zantac (ranitidine) was a widely used heartburn medication that was found to contain N-nitrosodimethylamine (NDMA), a probable human carcinogen. In 2020, the FDA requested a market withdrawal for Zantac due to these concerns. Our pharmaceutical attorneys are helping individuals who developed cancer after taking Zantac for extended periods. 

Learn more about Zantac Cancer Lawsuits

Ozempic Lawsuit

Ozempic (semaglutide) is a popular diabetes and weight loss medication that has been linked to serious adverse effects, including pancreatitis, gallbladder disease, and severe gastrointestinal issues. Our pharmaceutical attorneys are investigating claims for affected patients. 

Learn more about Ozempic Lawsuits

Suboxone Lawsuit

Suboxone (buprenorphine/naloxone) is used to treat opioid dependence. It is associated with serious side effects and allegations of anticompetitive practices by its manufacturer. Our law firm represents individuals harmed by this medication.

What is the Legal Process for a Drug Injury Lawsuit?

When you work with our California pharmaceutical attorneys, we handle every aspect of your case from start to finish:

Initial Consultation and Case Evaluation

The process begins with a free, confidential consultation where our lawyers will review your medical history, drug usage, and resulting injuries to determine if you have a viable claim. We will explain your legal options and what to expect throughout the legal process.

Investigation and Evidence Gathering

Our pharmaceutical attorneys will collect comprehensive evidence to support your case, including:

  • Medical records documenting your injuries.
  • Scientific studies linking the medication to your specific injuries.
  • Expert testimony from medical professionals.
  • Internal company documents showing knowledge of risks and any misconduct related to your claims.
  • FDA warnings and communications about the medication.

Filing Your Lawsuit

Our pharmaceutical lawyers will prepare and file a detailed complaint in the appropriate jurisdiction, whether in state court, federal court, or as part of multidistrict litigation (MDL). The complaint will outline your injuries, the defendant's alleged liability, and the compensation you are seeking.

Discovery Phase

During discovery, both sides exchange information and evidence. Our pharmaceutical attorneys will depose key witnesses, including company executives and medical experts. We also review internal company documents to determine whether the company engaged in any misconduct related to your claim, and to build the strongest possible case. Our firm is known for getting confidential company documents “unsealed” and publishing important “smoking gun” documents that are important to public health and safety. 

Pharmaceutical Settlement Negotiations

Many cases resolve through settlement negotiations. Our law firm will advocate for maximum compensation that fully accounts for your medical expenses, lost income, pain and suffering, and other damages. We will advise you of the strength of any settlement offer, but the final decision to accept remains yours.

Trial Preparation and Litigation

If a fair settlement cannot be reached, our pharmaceutical attorneys are fully prepared to take your case to trial. We have extensive courtroom experience and will present compelling evidence and testimony to demonstrate the pharmaceutical company's liability and the extent of your damages.

Statute of Limitations for Pharmaceutical Claims

Each state has a deadline for filing a drug injury lawsuit. In California, the statute of limitations for filing a pharmaceutical lawsuit is generally:

  • Two years from the date of injury or diagnosis
  • One year from when you discovered (or reasonably should have discovered) that the defective drug caused your injury

For cases outside California, different timeframes may apply. Additionally, the statute of limitations may be extended through various legal doctrines, including:

  • Discovery rule (when the connection between the drug and injury became apparent)
  • Fraudulent concealment (if the manufacturer deliberately hid information)
  • Continuing violation doctrine (for ongoing exposure to the defective drug)

To protect your legal rights, it is crucial to consult with a defective drug lawyer as soon as possible after discovering an injury. Our pharmaceutical attorneys can help determine the applicable deadlines in your specific case.

Legacy Pharmaceutical Litigation – Advocacy Beyond the Courtroom

Wisner Baum’s track record of success in pharmaceutical litigation dates back to the 1980s. Our pharmaceutical attorneys have not only won landmark cases against Big Pharma; we have also spearheaded and participated in numerous campaigns to address and correct industry practices that caused our clients to suffer harm. While our efforts may not directly have impacted our casework, we have always fought—and will continue to fight—for safety improvements that have the potential to prevent similar harm from happening in the future. 

As managing partner, R. Brent Wisner said in an interview with Super Lawyers Magazine: 

"We get these really incredible documents that affect people's public health, and we make a point to get them unsealed. Most lawyers don't bother or care to do that because it doesn't really affect the case; but for us it's a greater good kind of thing."

Zoloft Suicide and Efficacy Lawsuits 

Lawsuits were filed against Zoloft-maker, Pfizer in the early 2000s alleging the drug caused an increased risk of suicidal behavior, and in the late 2000s, a lawsuit was filed claiming the manufacturer overpromoted the drug’s efficacy.

Internal documents showed Pfizer was aware of Zoloft’s questionable efficacy in treating depression and that the FDA approved the drug despite its efficacy shortcomings only because the FDA’s standard for approving antidepressants is “not as demanding as it ought to be.”

Paxil Suicide Lawsuits

GlaxoSmithKline (GSK) faced hundreds of lawsuits alleging Paxil could induce suicidal behavior in both adults and children/adolescents.

Unsealed internal documents obtained in the litigation showed the Paxil pediatric clinical trials all failed to outperform placebo on primary efficacy measures and that the drug posed a suicidal behavior risk (which GSK misleadingly coded as “emotional lability”) to young people.  Nonetheless, the company promoted Paxil as efficacious and denied any suicide risk, using Key Opinion Leaders (KOLs) and ghostwriting positive medical journal articles, contrary to the underlying data.  

Documents also showed the company was aware that adult patients given Paxil during clinical trials experienced suicidal behavior at a rate nearly nine times greater than patients given a placebo. 

Cymbalta Withdrawal Lawsuits

Our cases alleged that Eli Lilly & Company omitted important information about Cymbalta withdrawal risks in the company's labeling and marketing materials, preventing consumers from making informed choices about whether to take Cymbalta.

Declassified court documents obtained by our firm during litigation showed that Eli Lilly was well aware of Cymbalta's withdrawal risks, which occur frequently and can be severe. Instead of disclosing the risk, Lilly hid behind a misleading label, making it appear the risk was rare and the symptoms mild.

Celexa and Lexapro Lawsuits

This class action lawsuit alleged that Forest Pharmaceuticals engaged in a program of deceptive conduct around pediatric depression treatment. Using a misleading drug label, the "endorsements" of paid opinion leaders, gerrymandered clinical trials, and specially trained sales personnel, Forest misled consumers and the medical community about Celexa's and Lexapro's efficacy in treating pediatric depression.

Documents unearthed during our civil lawsuits revealed that Forest Pharmaceuticals deliberately misled the Department of Justice during its investigation and 2010 settlement. The government's investigation was just the tip of the iceberg—our documents showed much deeper deception than the government ever suspected. 

Actos Bladder Cancer Lawsuits

Actos (pioglitazone), manufactured by Takeda Pharmaceuticals USA, is prescribed for blood sugar control in Type 2 Diabetes. Our lawsuits alleged that Actos caused bladder cancer in patients. The documents and court transcripts from this litigation show Takeda misled the FDA and healthcare community regarding Actos' efficacy and safety, hiding harmful side effects that surfaced in clinical trials.

Documents obtained in the discovery phase of litigation revealed that Takeda's US partner, Upjohn, had backed out of the partnership after clinical trials showed the drug posed safety and efficacy risks. The drug was marketed as a safer alternative to Avandia, despite known risks. 

Blood Products Lawsuits

This litigation involved Bayer and its company Cutter Laboratories, which manufactured AHF (anti-hemophiliac factor), a blood product used by hemophiliacs to treat uncontrolled bleeding. In the early 1980s, Cutter Laboratories realized that its AHF was contaminated with HIV, but its financial investment in the product was considered too high to destroy the inventory.

Cutter continued to sell the contaminated AHF to markets willing to accept it, including overseas markets in Asia and Latin America, without heat treating the product to eliminate HIV risk. Customers were not informed of the risk, and as a consequence, hemophiliacs who used the HIV-contaminated AHF developed AIDS.

Our firm fought to unseal documents, which revealed the illegal collection of HIV-contaminated plasma from unhealthy donors and the subsequent "dumping" of defective products in international markets, leading to major media investigations, including coverage by The New York Times.

FAQs

Yes. We are a California-based law firm, but our team of pharmaceutical drug lawyers represents clients across all 50 states. We have offices in Los Angeles, the San Francisco Bay Area, and Washington D.C.

Yes, you may be able to sue for drug side effects if you suffered serious harm that was not properly disclosed, or if the medication was defectively designed, manufactured, or marketed. Many states allow patients to take legal action against pharmaceutical companies when side effects cause significant injuries—especially if the company failed to provide adequate warnings, misrepresented the drug’s safety, or sold a defective product.

To have a valid lawsuit, you generally need to show:

  • The drug caused an unexpected or serious injury or complication.
  • Your injury was linked to a defect in the drug, a failure to warn about dangers, and/or improper marketing (such as promoting for unapproved uses).
  • You suffered financial, physical, or emotional harm as a result of taking the drug.

Drug side effect claims can be brought individually or as part of a larger group (mass tort). Taking action as soon as you are able is important because strict legal deadlines (statutes of limitations) apply. An experienced drug injury attorney can review your circumstances, explain your options, and help you pursue compensation for medical bills, lost wages, pain and suffering, and more

Most pharmaceutical attorneys—including our team—work on a contingency fee basis, which means you pay nothing upfront and owe no legal fees unless we win compensation for you through a settlement or verdict. Your initial consultation is always free. If we take your case, our firm advances all legal expenses—including expert witnesses, medical reviews, and court costs—so you never have to pay anything out-of-pocket. Our fee is simply a percentage of the compensation we recover for you, agreed upon before representation begins. 

If we don’t recover money for you, you owe us nothing.

You may have a basis to file a drug lawsuit if you took a prescription medication as directed and developed a serious side effect or injury or the manufacturer did not adequately warn about the potential risks, and you required medical treatment as a result. The timing between taking the medication and developing symptoms is also important. Our pharmaceutical drug lawyers can evaluate your specific situation during a free consultation to determine if you have a viable claim.

Yes. FDA approval doesn't shield pharmaceutical companies from liability. Drug manufacturers have an ongoing duty to monitor the safety of their products and update warnings as new risks are identified. If a company fails to adequately warn about risks, conceals information from the FDA, or engages in deceptive marketing practices, it can be held liable regardless of FDA approval.

Multiple parties may be liable in pharmaceutical litigation, including drug manufacturers, distributors, marketing companies, testing laboratories, and, in some cases, healthcare providers who prescribe the medication despite known contraindications. Our pharmaceutical attorneys will identify all potentially responsible parties in your case.

In a pharmaceutical lawsuit, you pursue compensation for your specific injuries, with your case evaluated based on your unique circumstances and damages. In some cases, your case will be consolidated into a federal multidistrict litigation (MDL) or a state court variant. While an MDL shares similarities to a class action, it is notably different in a few important ways

In a class action, a representative plaintiff brings a case on behalf of many people with similar claims, with any settlement distributed among all class members. Mass tort litigation (such as multidistrict litigation or MDL) combines aspects of both approaches, with cases consolidated for efficiency while each plaintiff's injuries and compensation are evaluated individually.

The timeline for pharmaceutical litigation varies widely depending on factors such as the complexity of the medical issues, the number of plaintiffs, the strength of scientific evidence, whether the case is part of multidistrict litigation, and the defendant's willingness to settle. 

Some cases resolve within 1-2 years, but these are the exception, not the rule. Complex pharmaceutical litigation may take several years. Our drug injury lawyers work efficiently to resolve your case as quickly as possible while still pursuing maximum compensation.

Compensation in pharmaceutical litigation may include:

  • Past and future medical expenses related to your injuries.
  • Lost income and reduced earning capacity.
  • Pain and suffering, both physical and emotional.
  • Diminished quality of life and loss of enjoyment.
  • Loss of consortium (impact on relationship with spouse).
  • Wrongful death damages for surviving family members.
  • Punitive damages in cases of egregious misconduct by the manufacturer.

The specific damages available depend on your particular circumstances, the severity of your injuries, and applicable state laws.

If you suspect a medication has caused you harm:

  • Consult with your healthcare provider about your concerns (do not stop taking medication without medical advice).
  • Document all symptoms, when they began, and any medical treatments received.
  • Keep all medication packaging, receipts, and prescription information.
  • Request and save copies of relevant medical records.
  • Contact an experienced attorney to evaluate your claim.

Possibly. Even if a side effect was mentioned on the label, you may have a case if the warning was not sufficiently prominent or clear, understated the risk or severity, was added after you suffered harm, or if the drug was marketed in a way that downplayed the warnings. Our pharmaceutical attorneys can evaluate whether the warnings were legally adequate in your specific case.

If multiple medications potentially contributed to your injury, our lawyers will work with medical experts to determine which drug or combination of drugs was responsible. We may pursue claims against multiple pharmaceutical companies if appropriate. The complex nature of these cases highlights the importance of working with attorneys experienced in pharmaceutical litigation.
