Portner & Shure Handles Complex Injury Cases

It can be painful and frustrating when the very things that are supposed to heal you do the exact opposite. When manufacturers fail to adequately warn of potential side effects, or sell products that are defective and dangerous, they must be held accountable for their negligence. A mass tort action can help you seek compensation for your damages and protect others from future injuries.

If you’ve been injured by faulty medical devices or dangerous prescription drug, the mass tort attorneys of Portner & Shure can help. Everyone deserves justice, which is why we proudly include Spanish, Vietnamese, Korean, Mandarin Chinese, and Cantonese Chinese speaking paralegals among our dedicated legal team.

What Is a Mass Tort?

Mass torts involve several injured plaintiffs whose injuries are alleged to have been caused by the same corporate defendants. Mass tort actions are different from class-action lawsuits because in a mass tort lawsuit, each plaintiff is treated as an individual instead of as part of an entire group. Therefore, if one plaintiff lacks the necessary facts to successfully sue in a mass tort action, then that plaintiff will not be successful.


Millions of Americans have taken Zantac (or the generic form ranitidine) to treat their heartburn, acid reflux, gastroesophageal reflux disease, and sour stomach.

Recent evidence suggests that people taking Zantac may have been exposed to high levels of a cancer-causing chemical. Consumers around the country are now taking legal action against major drug companies for failing to warn them of this danger.

Financial compensation may be available through a Zantac lawsuit for individuals suffering or diagnosed with:

  • Liver Cancer
  • Small intestine cancer
  • Esophageal Cancer
  • Pancreatic Cancer
  • Bladder Cancer
  • Stomach Cancer
  • Prostate cancer
  • Kidney cancer
  • Thyroid Cancer

The experienced attorneys at Portner & Shure, P.A. will evaluate your Zantac case and help you, and your family, determine if you may have a claim for Zantac exposure. This initial consultation is free. Remember, we do not obtain any fees unless you are awarded compensation.

what is Zantac?

Zantac, or ranitidine, was first introduced in 1983. By 1989, Zantac was the world’s best-selling drug. It was available over the counter or as a prescription. Rantidine, the active ingredient in Zantac, belongs to a class of antacid drugs called H2 blockers, or histamine-2 receptor agonists.

Zantac treats heartburn with acid indigestion and sour stomach caused by eating or drinking certain foods or beverages.

In 2018, according to Bloomberg Intelligence, nearly 25 million prescriptions for ranitidine were written.

In April of 2020, the United States Food and Drug Administration (“FDA”) requested manufacturers withdraw all prescription and over-the-counter ranitidine drugs from the market immediately. The FDA cited concerns of contamination with N- Nitrosodimethylamine (“NDMA”), which is a chemical impurity that could cause cancer. The FDA determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures it may result in consumers being exposed to unacceptable levels of this impurity.

If you, or a loved one, has been diagnosed with cancer after taking Zantac you may have a claim. Call us today for a free initial consultation to determine if you may be entitled to compensation.

Active Drug Injury Investigations & Litigation

When you take a prescribed or over-the-counter drug, you trust it will be effective and safe. You would certainly never expect the drug to cause more harm than good. If medications are known to be defective, drug companies should not profit by selling them. Current drug injury investigations and litigation include:

Nexium & Prilosec OTC

We’ve all seen the commercials: "one pill a day, 24 hours, zero heartburn!" These medications, such as Nexium and Prilosec OTC, are advertised as safe and effective, but harbor serious, life-threatening side effects.

Medications such as Nexium and Prilosec OTC are proton-pump inhibitors (PPI) that are used to treat acid reflux, heartburn, ulcers and gastrointestinal problems. While PPI meds tend to work well for their intended use, overuse of these drugs can result in serious side effects that many users are not made aware of. Since warning labels do not adequately warn about potential risks associated with long-term use, many users continue to use PPI meds for several years.

Proton-pump inhibitors increase the risk of severe kidney injury, including:

  • Chronic kidney disease
  • Dialysis
  • Renal/kidney failure
  • Acute interstitial nephritis
  • Increased risk of heart attack by 15-20%

More than 15 million people use Nexium and Prilosec OTC, making them some of the most popular medications in America. Prilosec OTC was developed in 1989 as a prescription drug; currently is an over-the-counter drug. Nexium was developed in 2001, and in 2014, the FDA required the drug manufacturer to include new warnings because it was not approved for long-term use.
