Class action lawsuits let people take legal action as a group when harmed by the same product or company. In 2025, these cases are on the rise – especially in drug safety, defective products, and tech-related harm.
Some of the biggest lawsuits involve claims of cancer, hearing loss, organ damage, and even dental issues. One of the fastest-growing mass torts is the Suboxone lawsuit, where users report severe tooth decay from a treatment meant to help with addiction.
These cases often move through MDLs, where hundreds of lawsuits are handled together. It is complex but powerful.
In this blog, we will walk through some of the biggest class action lawsuits currently active in 2025. If you believe you have been affected, it is important to speak with experienced product liability lawyers who can guide you through the process.

What Is a Class Action Lawsuit?
A class action lawsuit is a legal case filed by a group of people who were harmed in a similar way by the same company or product. Instead of filing separate lawsuits, one case is filed for the whole group.
You must have heard about cases like Innovasis lawsuit, where a lot of people have come together to hold someone or a corporation accountable. Well, that’s a great example of a class action lawsuit!
These lawsuits are common in cases involving unsafe drugs, faulty products or false advertising. They help people join together and take action against large companies.
Many class actions go through something called MDL, which helps manage a large number of similar cases more easily.
With support from experienced product liability lawyers people can seek justice and possible compensation without having to go through it alone.
Current Class Action Lawsuits of 2025
Class action lawsuits in 2025 cover a wide range of issues. From dangerous drugs to defective devices and misleading tech platforms, people are standing up and taking legal action. Here’s a detailed look at some of the biggest and most active lawsuits this year.
1. Suboxone Tooth Decay Lawsuit
The Suboxone lawsuit is currently part of a multidistrict litigation (MDL), and while it is not a class action, some expect it could take that form if future rulings support it.
Suboxone is a drug used to treat opioid addiction. But now, hundreds of patients are reporting serious dental damage. They say the drug caused dry mouth which led to tooth decay, gum infections, and even tooth loss.
The problem? The manufacturer, Indivior, didn’t warn users until the FDA stepped in. In 2025, nearly 900 cases are part of an MDL in federal court.
The number of Suboxone lawsuit is expected to rise sharply as more people come forward. Product liability lawyers are helping victims collect evidence and file claims.
2. Talcum Powder Lawsuit
This is one of the largest MDLs of the year, with over 58,000 cases pending. People who used Johnson & Johnson’s talcum powder for years are claiming it caused ovarian cancer.
The company tried to settle through bankruptcy but failed again in March 2025. The litigation is active once more and could lead to a major payout if it does not settle soon.
3. Hair Relaxer Cancer Lawsuit
This MDL targets chemical hair relaxers linked to uterine and ovarian cancer. Many plaintiffs are Black women who used these products for years. As of 2025, over 9,800 lawsuits have been filed. While growth has slowed, the size of the potential plaintiff group remains large.
4. C.R. Bard Hernia Mesh Lawsuit
This case involves faulty hernia mesh implants made by Bard. These devices caused infections, pain, and further surgeries. Over 24,000 lawsuits are pending.
A major settlement was reached last year, but new cases are still being filed. Victims need help from product liability lawyers to prove injury and join the MDL.
5. Paraquat Parkinson’s Lawsuit
Paraquat is a weedkiller linked to Parkinson’s disease. Around 6,000 cases are pending. A settlement was reported in April 2025, but many state court cases remain. This lawsuit is important because Parkinson’s is a lifelong, serious condition.
6. Social Media Addiction Lawsuit
This MDL involves over 900 cases. The lawsuits claim that companies like Meta, TikTok, and YouTube created addictive platforms that harmed young users.
Issues include anxiety, eating disorders, and even suicidal thoughts. The platforms are trying to defend themselves using legal protections, but so far the cases remain strong.
7. Tepezza Hearing Loss Lawsuit
Tepezza is a drug for thyroid eye disease. Many users say it caused permanent hearing loss. These lawsuits are growing slowly but are expected to pick up. Experts believe they have strong legal ground.
8. Roundup Cancer Lawsuit
Roundup is a weedkiller linked to cancer. After some large verdicts in past years, Bayer (which owns Monsanto) started settling claims.
But they also began selecting weaker cases for trial. They lost five in a row recently, costing billions. Regulators or plaintiffs may now force the company to settle again.
9. Paragard IUD Lawsuit
The Paragard IUD has been breaking during removal. Fragments left behind caused pain and required surgery. The MDL now has nearly 2,900 cases. Progress has moved slowly, but courts expect the first bellwether trials to begin this year.
10. Bard PowerPort Lawsuit
Doctors use this device to deliver medication through the bloodstream. Plaintiffs say it often fractures or moves inside the body, causing serious harm. The MDL started with just 150 cases but now has close to 900. That number is still climbing.
11. Valsartan Cancer Lawsuit
Manufacturers contaminated some batches of this blood pressure drug with NDMA, a cancer-causing substance. Over 1,200 lawsuits are pending. Courts expect the first trial to begin later this year.
12. Depo-Provera Brain Tumor Lawsuit
New studies show this birth control shot may raise the risk of brain tumors. This issue could affect thousands of women. This MDL is likely to grow fast in 2025.
13. Uber Driver Sexual Assault Lawsuit
Passengers filed lawsuits claiming Uber drivers assaulted them. These cases accuse Uber of failing to monitor or act on red flags. The MDL is still new but expected to expand quickly.
14. AFFF Firefighting Foam Lawsuit
Researchers have linked the toxic “forever chemicals” in this foam to cancer in firefighters and military personnel. With over 7,600 pending cases, this MDL may settle soon. Many municipalities have already received payouts.
15. Heavy Metal Baby Food Lawsuit
Finally, on this list is the current Baby Food Autism lawsuit! Tests found dangerous levels of metals like lead and arsenic in baby food. This lawsuit targets big brands like Gerber and Walmart. Courts formed the MDL in 2024, and it continues to grow in 2025.
How Product Liability Lawyers Support Suboxone Lawsuit and Class Action Cases
Filing a lawsuit on your own can feel overwhelming. That’s where product liability lawyers can help. They know how to handle complex legal cases involving dangerous drugs, faulty devices, and harmful products.
In the case of the Suboxone lawsuit, these lawyers are helping patients gather dental records, prove damage, and file their claims in federal court.
They also manage all communication with the court and the drug manufacturer. This is important because Suboxone-related injuries vary. Some people need root canals or extractions. Others have permanent damage. A good lawyer will calculate fair compensation based on the actual harm.
In other class action lawsuits, such as those involving talcum powder or hernia mesh, product liability lawyers work to get settlements for large groups of people. They understand MDLs and know how to move cases forward quickly.
If a product has hurt you, act now. The right legal team can help protect your rights and increase your chances of a strong outcome.
