What to Know About Recent Metformin Recall and Settlement Claims

Teva Pharmaceuticals, Granules USA and Heritage Pharmaceuticals agreed to pay a combined $5.55 million class action settlement to resolve claims their metformin products were contaminated with cancer-causing N-nitrosodimethylamine (NDMA). Metformin is one of the most commonly prescribed medications for type 2 diabetes, making this settlement significant for millions of people across the country. The settlement process is now open, and eligible consumers have a limited window to file claims for compensation.

Unlike personal injury lawsuits, this settlement focuses on economic-loss claims brought by consumers and third-party payors who allegedly paid for metformin products that were contaminated, adulterated, or worth less than what they paid. If you purchased generic metformin from certain manufacturers during a specific period, you may qualify to recover a portion of what you spent.

What Is NDMA and Why Does It Matter?

Some diabetes drugs have been found to be contaminated with higher-than-acceptable levels of the nitrosamine impurity N-nitrosodimethylamine (NDMA). This contaminant raised regulatory and safety concerns because of its potential to cause harm with long-term exposure. The metformin issue came after similar nitrosamine contamination concerns involving other drugs, including ranitidine and certain blood pressure medications. Those earlier cases helped bring more public attention to the question of how impurities can appear in widely used generic medications and how quickly manufacturers and regulators respond when contamination is detected.

The discovery of NDMA in metformin products prompted investigation and legal action, even though no formal product recall was issued at the federal level. The lawsuits alleged that manufacturers either knew or should have known about this risk and failed to address it properly.

The Three Pharmaceutical Companies Involved

The companies deny wrongdoing. They have not admitted liability, and the settlement does not mean a court found that they violated the law. Instead, they agreed to settle to resolve the economic-loss claims without admitting fault. Important to note: the settlement will not apply to brand-name metformin products unless the settlement materials specifically identify them as covered. It will not apply to every generic manufacturer.

Who Qualifies for the Settlement?

To be eligible for compensation, you must meet several basic criteria. Individuals and entities may be eligible to participate in the settlement if they are located in the United States, its territories or possessions, and they paid any amount of money for a metformin-containing drug (for personal or household use) that Teva, Granules or Heritage manufactured, distributed or sold between July 20, 2015, and June 2, 2020.

If you purchased metformin during this five-year window and have any documentation proving the purchase, you may qualify. Third-party payers (such as health plans) must have paid or reimbursed some or all of the purchase price for a metformin-containing drug to be eligible as a different type of claimant.

It is important to understand what this settlement does not cover. The settlement will not provide personal injury compensation. This means if you believe you suffered health damage from the contaminated medication, this settlement is not the appropriate avenue for that claim. The settlement is purely about refunding what you paid for a product that turned out to be worth less than advertised.

How to File a Claim

The claims process is straightforward and designed to be accessible without requiring a lawyer or complex documentation. It's free, it takes 10 minutes, and you don't have to prove you were harmed — just that you bought it. Here are the essential steps:

• 📋 Visit the official settlement website at InReMetforminSettlement.com
• 📋 Click "File A Claim" to access the online claim form
• 📋 Fill out the form with information about when you purchased metformin, the approximate quantity, and how much you paid
• 📋 Gather supporting documentation such as pharmacy receipts, insurance Explanation of Benefits (EOBs), bank statements, credit card statements, or doctor's notes
• 📋 Submit your completed claim by July 10, 2026

You have the option to file online or by mail. If mailing your claim, send it to the address provided on the settlement website and ensure it is postmarked by the deadline. For questions during the process, you can call the settlement administrator at 1-866-302-6835.

Critical Deadline and Timeline

The deadline to submit a claim is July 10, 2026. This is a firm deadline, and claims submitted after this date will not be accepted. Given that metformin is often taken daily over many years, it can be challenging to locate all relevant documentation, so starting your search and claim preparation well in advance of this date is wise.

After the claim deadline, the settlement moves to final approval. The court will determine whether to grant the settlements final approval following a hearing on August 12, 2026. Compensation will begin to be distributed to class members only after final approval has been granted and any appeals have been resolved.

Finding and Organizing Your Records

One of the biggest challenges for eligible claimants is locating proof of purchase from a medication taken years ago. Consumers should keep prescription records whenever possible, especially for medications taken long term. Pharmacy histories, EOBs, refill records, and medication labels can become important years later when recalls, settlements, or safety issues arise.

Start by contacting the pharmacy where you regularly filled prescriptions during the 2015-2020 period. Many pharmacies maintain purchase records that extend back several years, and staff can help you identify which metformin products you purchased and when. Insurance companies also keep detailed records of prescriptions they reimbursed, which are available through online portals or by requesting them directly.

Expected Payout and What It Means

The total settlement fund is divided among all eligible claimants who file valid claims before the deadline. Because the pool of potential claimants is very large—metformin is widely prescribed—individual payouts are likely to be modest. However, for people who purchased qualifying products from the covered manufacturers, it may provide a way to recover part of what they paid. Even if the amount per claim is not substantial, claiming what you are owed requires minimal effort and costs nothing.

Key Takeaways for Consumers

• 💊 This settlement applies only to generic metformin made by Teva, Granules, or Heritage purchased between July 2015 and June 2020
• 💊 You do not need to prove you were harmed—only that you purchased the medication
• 💊 The deadline to file a claim is July 10, 2026, and missing this date disqualifies you
• 💊 Filing is free, online, and typically takes around 10 minutes
• 💊 Gather any documentation of your purchases—pharmacy records, insurance statements, or credit card statements—before filing
• 💊 Individual payouts will depend on how many claims are filed, but claiming requires minimal time and cost

If you took metformin during the identified time period and purchased a generic version made by one of the three settling manufacturers, taking a few minutes to file a claim is a straightforward way to recover what you paid. The settlement process reflects how regulatory and legal systems respond when contamination is discovered in widely used medications, and it serves as a reminder of the importance of keeping medication records for your own records and potential future claims.
