From widely prescribed diabetes drugs to cow’s milk-based infant formulas used in hospitals, pharmaceutical companies are facing a growing wave of lawsuits in the U.S.
These cases are not isolated. Instead, they reflect a broader legal trend that’s seen rapid growth in recent years and shows no sign of slowing down.
For many Americans, the surge in defective and dangerous drug cases raises a basic question: Why are pharmaceutical lawsuits so common?
The number of everyday medications and health products involved in these cases has also led to increasing concerns about whether drugmakers can be trusted to create safe products. The current birth control shot lawsuits are a prime example of this. Millions of women have learned they may be at an increased risk of brain tumors from using Depo-Provera.
With pharmaceutical lawsuits seemingly everywhere right now, attorneys and experts have been weighing in on what’s causing the influx. They say the answer comes down to a mix of factors:
When One Product Reaches Millions, Lawsuits Can Multiply Quickly
Numerous medications are used by millions of people at once. That means even a rare side effect can result in high numbers of injuries, and eventually, result in dangerous drug lawsuits. Since the type and cause of harm is often similar, pharmaceutical cases frequently end up being consolidated into multidistrict litigation (MDL), which increases awareness of mass litigation.
This dynamic – widespread use of a drug and similar injuries among plaintiffs – is playing out right now in several ongoing cases, including lawsuits involving GLP-1 weight loss drugs.
As of April 2026, there were more than 3,500 dangerous pharmaceutical lawsuits in the weight loss drug MDL against Ozempic, Wegovy, and Mounjaro. Plaintiffs allege their products cause severe gastrointestinal issues, including stomach paralysis and intestinal obstruction.
A second MDL with cases claiming GLP-1 drugs cause blindness and other eye problems was created in December 2025, but the current lawsuits could just be the beginning. Other side effects are being linked to the weight loss medications, including recent reports that Ozempic may cause scurvy.
Pharmaceutical Lawsuits Often Begin Years After a Drug Hits the Market
One reason pharmaceutical litigation can seem sudden and so common is that cases often start being filed long after a product is introduced and approved by the U.S. Food and Drug Administration (FDA). This means that a medication with serious but unknown side effects could be used for decades before illnesses are diagnosed or for symptoms to begin, which then results in a large pool of patients who suffer harm.
It takes time for health problems to be connected to a drug when patients and doctors weren’t warned that a medication could cause the side effect. And then it takes even longer to collect evidence, consult with experts, and file a lawsuit.
This is why so many dangerous pharmaceutical lawsuits focus on “failure to warn”. Plaintiffs argue that patients were not given enough information to make informed decisions because the company knew or should have known of the risks but failed to warn of them. A prime example of this is the ongoing Depo-Provera brain tumor lawsuits.
Internal Evidence Can Cause an Influx of Dangerous Drug Claims
Once lawsuits are filed, the legal process allows attorneys to gather evidence through the discovery process, including company files. These documents may include emails, safety analyses, and marketing strategies.
If these materials suggest a company knew about risks or failed to act on them, the impact on pharmaceutical lawsuits can be significant. A single case can quickly evolve into thousands of similar claims, especially when they’re consolidated into MDL because it raises awareness of what’s happening.
High Verdicts and Settlements Reflect the Severity of Medication Injuries
Pharmaceutical lawsuits often involve life-altering harm, including permanent disability, chronic illness, and in the worst case, death. Because of this, settlements and jury awards for compensatory damages frequently reach millions of dollars, if not more.
The potential for large verdicts due to severe harm caused by a medication is another reason pharmaceutical lawsuits are so common in the U.S.
Such injuries or illnesses may need aggressive treatments or surgeries, require months off work, cause parents to be unable to provide for or take care of their family, and/ or cause significant emotional harm, pain and suffering. This often results in a staggering jury award or settlement.
While not overly common, sometimes juries award punitive damages on top of compensatory damages for medical bills, lost income, and pain and suffering. The purpose is to punish pharmaceutical companies for their misconduct and gross negligence.
This April, a $70 million verdict against Abbott Laboratories was awarded to a group of four families that filed baby formula lawsuits. It included $17 million in punitive damages. Plaintiffs alleged the company failed to warn about the risk of necrotizing enterocolitis linked to its preterm infant formula.
U.S. Legal System Designed Largrscale Harm
Another key reason pharmaceutical lawsuits are so common is the structure of the U.S. legal system, which is equipped to handle largescale injury claims like mass torts.
Through MDLs and contingency fees, Americans who might not otherwise be able to afford hiring a lawyer can still pursue claims. The system works for law firms, too. They’re able to coordinate large groups of plaintiffs, making it possible to take on complex pharmaceutical cases.
When an MDL is created for similar dangerous drug cases, evidence can be shared and the legal process is streamlined. Then there’s bellwether trials, which usually influences the outcome of the rest of the cases by leading to settlements.
Dangerous Pharmaceuticals and the FDA
As widespread dangerous pharmaceutical lawsuits continue, questions have been raised about the role and impact of regulatory agencies, like the U.S. Food & Drug Administration (FDA). Recent cases have shown that the U.S. was far slower to respond than other developed countries when it came to updating labels and prescribing information.
For example, the FDA approved a Depo-Provera label change to include the risk of meningiomas in December 2025. Comparatively, Canada and Europe made this update more than a year earlier, and in 2022, parts of Europe began advising doctors to monitor patients using the birth control shot because of the link to meningiomas.
What to do If Injured by a Medication
Every day, Americans depend on medications and other pharmaceutical products to manage diseases and improve their health. Unfortunately, this doesn’t always happen, and the impact of being harmed by a dangerous drug can cause immeasurable consequences.
The rise in dangerous pharmaceuticals litigation in the U.S. is not driven by a single factor. Instead, it reflects a combination of widespread use of medications, delayed discovery of risks, laws that allow cases to scale, and high financial stakes tied to serious injuries.
As new drugs enter the market and long-term data continues to emerge, legal experts say one thing is certain: Pharmaceutical litigation and dangerous drug mass torts will remain central forces in the U.S. legal system for years to come.
