Prilosec Lawsuits


Studies suggest a common type of heartburn medication called proton pump inhibitors (PPIs) are linked to increased risks of chronic kidney disease. This class of drugs includes popular brands such as Prilosec (Omeprazole), Nexium and Prevacid. Damages may be available for affected consumers.

The Journal of the American Medical Association (JAMA) published results of a study showing that people who take Prilosec and other Proton Pump Inhibitor (PPI) medications may have a 20 to 50 percent increased risk of chronic kidney disease. The study indicates that the longer the medication is taken, the greater the risk.

Researchers found the risk of end-stage kidney failure is 96 percent higher for those taking PPIs, particularly those using the drugs for many months or years. Some experts are calling the increase of kidney issues in the American public an “epidemic.”

An estimated 15 million Americans were prescribed PPIs in 2013 at a cost of more than $10 billion. However, the number of those at risk of health problems is likely to be much higher because most of these drugs, including Prilosec, Nexium, and Prevacid, are now available over-the-counter.

Lawsuits filed against PPI manufacturers such as AstraZeneca claim the companies have failed to provide adequate warnings about the risks their product presents. The Prilosec lawsuit claims allege companies knowingly hid dangers of their medications from the public. The uncovered kidney damage risks could affect thousands of Americans.

AstraZeneca has faced legal issues in the past. In fact, the company settled a $20 million class action lawsuit related to deceptive marketing of Nexium. The lawsuit claimed the drug company “defrauded” consumers with dishonest advertising. Prilosec Lawsuit Settlements are now being considered.

What Damages Are Available in a Prilosec Class Action Lawsuit?

Those who have been injured and are experiencing medical conditions due to Prilosec or omeprazole may be entitled to significant damages for their losses. 

Damages in a Prilosec class action lawsuit may cover: 

  • Medical Expenses: This may include hospital bills, costs of medications, surgery costs, and other related expenses.
  • Lost Wages: Compensation may cover lost wages due to missing work during recovery from the medical condition or injury.
  • Loss of Future Income: Damages may also cover losses associated with not being able to work anymore or working in a reduced capacity due to the Prilosec injuries.
  • Pain and Suffering: A lawsuit can help provide financial assistance for the pain, trauma, and psychological damage caused by the ordeal.
  • Loss of Companionship: In cases where the injuries result in a loss of intimacy with a partner, these types of damages may be available. In cases where a loss of life has occurred, wrongful death damages may also be factored in.

      What Is Prilosec?

      Prilosec, produced by AstraZeneca, was the first FDA approved Proton Pump Inhibitor (PPI), marketed to treat gastroesophageal reflux disease (GERD) and peptic ulcer disease (PUD).

      It is estimated that the company’s sale proceeds from Prilosec topped $6 billion by the year 2000. Up to 14 percent of adults in the U.S. have been prescribed Prilosec or other PPI medications, and many more may have taken over-the-counter medicines as well.

      In 2001, when Prilosec’s patent expired, AstraZeneca introduced a similar PPI drug called Nexium. Shortly after, in 2003, Prilosec became available over-the-counter. Most of the popular PPI medications, including Prilosec, Nexium and Prevacid, are now available over-the-counter.

      Prilosec Risks & Side Effects

      Several safety concerns have been identified over the years. In 2015, one study indicated that PPI drugs may increase the heart attack risk by up to 21 percent, even if the patients had no history of heart disease. Side effects of PPI drugs can include:

      • Pain in joints or muscles
      • Headaches
      • Intestinal disruption
      • Nausea
      • Rashes
      • Anxiety

      More serious adverse events may include:

      • Heart attack
      • Liver failure
      • Hypomagnesemia (low magnesium levels)
      • Osteoporosis and bone fractures
      • Liver toxicity
      • Cardiac issues

      What Are Some Common PPI Medications?

      The PPI group of medications includes nine drugs, including the following:

      • Prevacid
      • Prilosec
      • Nexium
      • Protonix
      • Aciphex
      • Zegerid
      • Dexilent
      • Kapidex

      If you have taken any of these medications and are experiencing kidney-related problems, seek medical attention immediately and contact a lawyer. An attorney can help advise you on your next steps and options. 

      FDA Prilosec Injury Warnings

      Concerns about the safety of Prilosec emerged as early as 2002. Recent results of studies are even more troubling as they have shown the risk in the consumer population may worsen over time. Such studies include:

      • Bone Fractures: A 2006 study published in the Journal of American Medical Association (JAMA) showed that long-term Prilosec use increased the risk of hip fractures, particularly in the elderly. In 2010, the FDA echoed a prior warning, and issued a new warning to consumers, stating that Prilosec may cause an increased risk in bone fractures.
      • Dependency: In 2009, a study showed that Prilosec use may lead to a dependency on the medication due to a “rebound” effect of stomach acid if a patient stops taking the medication. The study also had concerns regarding “withdrawal” from the drug.
      • Blood Issues: In 2011, the FDA issued another warning, this time regarding the long-term risk of Prilosec causing low magnesium levels in the blood. This in turn may cause neurological, muscular, and cardiac effects.

      Health risks associated with Prilosec and other PPIs may be compounded through long-term use. 

      If you have been using Prilosec consistently and are experiencing symptoms, contact The Lyon Firm at (513) 381-2333 for legal advice and representation. We have a consistent record of obtaining significant damage awards on behalf of our clients.

      PPIs and Chronic Kidney Disease

      PPI s may be linked to chronic kidney disease. Also known as chronic renal failure, this occurs when long-term damage is done to the kidneys, reducing the ability to filter toxins and metabolic products from the bloodstream. The kidneys become damaged and unable to filter blood as they should.  

      Chronic kidney disease can lead to total kidney failure and the need for dialysis or a kidney transplant. Chronic kidney failure is progressive and will get worse over time. 

      Chronic Kidney Disease may present with symptoms such as:

      • Swelling
      • Fluid in lungs
      • Arrhythmia
      • Hypertension
      • Electrolyte abnormalities
      • Nausea and Vomiting
      • Loss of Appetite
      • Inability to urinate
      • Fatigue

      These symptoms in themselves can be serious, and may also progress into more serious medical conditions, such as organ failure. Contact a lawyer if you developed chronic kidney disease after taking Prilosec.

      Are There Any Alternatives for Treating Heartburn Symptoms?

      Patients should take steps to ease heartburn-related symptoms through lifestyle changes. Losing weight, avoiding high-fat foods and avoiding eating late at night can be very helpful.

      There are safer ways to control unpleasant symptoms of heartburn, acid reflux, and ulcers. The most logical place to start is to utilize less-severe methods like diet changes and weight loss.

      There are also effective, less expensive, safer drugs available, such as antacids and H2 blockers which are not correlated to high rates of kidney damage.  

      Consumers should be wary of this new information, and contact a heartburn drug injury lawyer following kidney issues. Given the widespread use of these drugs, even a small increased risk of medical issues could have a considerable impact on public health.

      You should contact a lawyer as soon as you notice any symptoms if you have been taking Prilosec.

      The important thing is that you reach out to an attorney as soon as you think you have a claim or legal issue involved. Your attorney can help ensure your claim is addressed and all legal requirements are met for the lawsuit. 

      What documents and evidence should I prepare?

      While each lawsuit is different, if you have been injured by Prilosec or any other PPI medication, you should gather and prepare: 

      • Payment receipts and prescriptions
      • Medical records
      • Any statements from doctors or other medical professionals
      • A written account of your symptoms and what you are experiencing

      We understand that you may be injured or unwell and not able to gather all of these items. Don’t worry – it’s our job as attorneys to collect these and prepare them, but if you have access to them, it will help your case tremendously.
