Prevacid Lawsuit

Prevacid, like all proton pump inhibitors, one of the most commonly taken medications.

Millions of patients are prescribed Prevacid and other PPIs.

The manufacturer of Prevacid, Takeda Pharmaceuticals, makes millions of dollars from Prevacid every year. Prevacid is perhaps the best-known drug sold by Takeda in the United States.

Although Prevacid is still on the market, studies have shown links between the drug and an increased risk of medical conditions such as chronic kidney disease.

What Is Prevacid?

Prevacid is a proton pump inhibitor. It’s the brand name version of lansoprazole, which was developed in order to reduce the amount of acid produced by the stomach. It does this by blocking the production of stomach acid so that the cells in the stomach don’t produce stomach acid in the first place. It’s used to treat medical conditions that are caused by an excess of stomach acid.

What Kinds of Prevacid Are There?

Prevacid comes in several different varieties, some of which are over the counter and some of which may require a prescription. These include:

  • Prevacid
  • Prevacid 24HR
  • Prevacid Solu Tab

Who Manufactures Prevacid?

Prevacid is manufactured by the company Takeda Pharmaceuticals based in Japan. Takeda Pharmaceuticals was founded in 1781, later incorporated in 1925. Takeda Pharmaceuticals entered the US market in 1977 when it developed TAP Pharmaceuticals, a joint venture with Abbott Laboratories. The joint venture later split in 2008, which resulted in Takeda Pharmaceuticals obtaining the rights to the joint venture’s pipeline candidates and the rights to Prevacid.

When Was Prevacid Developed?

Lansoprazole was patented in 1984 by Takeda Pharmaceuticals. The company then launched the drug Prevacid in 1992. It was approved in 1995 by the FDA. By 2017, Prevacid had been prescribed to more than three million patients.

How Does Prevacid Work?

Prevacid, like other proton pump inhibitors, works by blocking the production of stomach acid. Lansoprazole, like the other types of proton pump inhibitors, does this by preventing the production of the enzyme H+/K+-ATPase in the stomach’s parietal cells, which produce stomach acid. The H+/K+-ATPase enzyme is called the proton pump because it triggers the production of acid in the stomach. Prevacid and other proton pump inhibitors are able to inhibit the production of the enzyme, thereby blocking the final step in the production process of the stomach’s acid.

What Is Prevacid Prescribed to Treat?

Prevacid is, like other proton pump inhibitors, is prescribed to treat medical conditions that involve the excess production of stomach acid, including:

  • Acid reflux
  • Heartburn
  • GERD
  • Zollinger-Ellison syndrome

What Is Acid Reflux?

At the bottom of the esophagus is a band of muscle that loosens to allow food and drink to pass through into the stomach. This band of muscle is called the esophageal sphincter and it normally tightens again after eating or drinking to prevent stomach acid from backing up into the esophagus. Sometimes, however, the esophageal sphincter doesn’t tighten properly and stomach acid is able to creep up into the esophagus. This is called acid reflux.

What Is Heartburn?

Heartburn is a burning sensation that is located behind the breastbone in the chest. It’s caused by the presence of stomach acid in the esophagus. The stomach lining is designed to protect itself against the harsh acid of the stomach that’s produced to break down food and drink. The esophageal lining isn’t meant to protect against stomach acid, so when stomach acid does back up into the esophagus, it causes a painful burning sensation.

What Are the Symptoms of Heartburn?

The symptoms of heartburn can include:

  • Burning chest pain that can be worse:
    • After eating
    • When lying down
    • When bending over
    • At night
  • At taste in the mouth that is:
    • Acidic
    • Bitter

If chest pain is severe or is accompanied by numbness in the arms, jaw, or face, the chest pain may actually be a sign of a heart attack and medical attention should be sought immediately.

What Is GERD?

GERD is an acronym that stands for gastroesophageal reflux disorder. GERD is essentially a worse form of acid reflux. Acid reflux can typically be managed with lifestyle changes and doesn’t occur frequently or severely. However, acid reflux is considered to be GERD when it:

  • Occurs twice or more weekly with mild symptoms
  • Occurs once or more weekly with severe symptoms

Some people are able to manage the symptoms of GERD with over the counter medication and lifestyle changes. Others, however, have the disorder severely enough that they need to see a doctor for a prescription.

What Are the Symptoms of GERD?

The symptoms of GERD can include most commonly:

  • Heartburn
  • Chest pain
  • Regurgitation of:
    • Food
    • Sour liquid
  • Trouble swallowing
  • The feeling of a lump in the throat

Some additional symptoms may be experienced by those who suffer from acid reflux during the night time. These include:

  • New asthma
  • Worsening asthma
  • Difficulty sleeping
  • Laryngitis
  • Chronic cough

What Is Zollinger-Ellison Syndrome?

Zollinger-Ellison syndrome is thankfully rare. Those who have the syndrome develop tumors in the upper part of the small intestine called the duodenum or in the pancreas. These tumors cause the parietal cells in the stomach to secret more than the normal amount of stomach acid. This can cause heartburn, GERD, acid reflux, and stomach ulcers.

What Are the Symptoms of Zollinger-Ellison Syndrome?

The symptoms of Zollinger-Ellison syndrome can include:

  • Diarrhea
  • Abdominal pain
  • Acid reflux
  • Heartburn
  • A feeling in the upper abdomen of:
    • Burning
    • Aching
    • Gnawing
    • Discomfort
  • Vomiting
  • Nausea
  • Digestive tract bleeding
  • Loss of appetite
  • Unintentional weight loss

What Are the Side Effects of Taking Prevacid?

The most common side effects of taking Prevacid include:

  • Headache
  • Diarrhea
  • Abdominal pain

Although rare, it is possible for patients to experience a severe allergic reaction to Prevacid. Anyone who is allergic to the drug should contact a doctor to seek medical treatment immediately. The symptoms of a severe allergic reaction include:

  • Rash
  • Itching
  • Swelling in the:
    • Face
    • Tongue
    • Throat
  • Severe dizziness
  • Changes to the amount of urine
  • Difficulty breathing

What Are the Severe Side Effects of Taking Prevacid?

The more serious side effects of taking Prevacid can include the following:

  • difficile infection
  • Low magnesium levels
  • Low vitamin B12 levels
    • Anemia
  • Lupus

What Is C. Difficile?

  1. difficile is a bacterium that can infect the body, typically in patients who are older and are in hospitals or in a long-term care facility. It can cause diarrhea or even inflammation of the colon, which can be life-threatening. Typically about half a million people are sick every year from the bacteria in the United States. However, cases of C. difficile infection are on the rise, especially amongst people who aren’t considered high risk for infection. On top of that, these infections are becoming more serious and more difficult to treat.
What Are the Symptoms of a C. difficile Infection?

The symptoms can include:

  • For a mild infection:
    • Watery diarrhea
      • Three or more times daily
      • For two or more days
    • Abdominal cramping
    • Abdominal tenderness
  • For a severe infection:
    • Watery diarrhea
      • 10-15 times daily
    • Severe abdominal pain
    • Severe abdominal cramping
    • Fast heart rate
    • Kidney failure
    • Fever
    • Dehydration
    • Nausea
    • Increased number of white blood cells
    • Bloody stool
    • Pus in stools
    • Swelling in the abdomen
    • Appetite loss
    • Weight loss

In the most severe cases, patients may be admitted to emergency care for the following symptoms:

  • Inflamed intestine
  • Enlarged colon
  • Sepsis

What Are the Symptoms of Low Magnesium?

The symptoms of low levels of magnesium can include:

  • A heartbeat that is:
    • Irregular
    • Unusually fast
    • Unusually slow
  • Muscle spasms
  • Seizures

What Is Anemia?

Anemia is a condition caused by a deficiency in red blood cells. There aren’t enough to adequately carry oxygen throughout the body. Most people are familiar with anemia being caused by low levels of iron in the blood. However, anemia can be caused by low levels of any nutrients that are involved in the process of creating red blood vessels. This includes vitamin B12.

What Are the Symptoms of Anemia?

The symptoms of anemia can include:

  • Weakness
  • Fatigue
  • Yellowish skin
  • Pale skin
  • Headaches
  • Cold hands
  • Cold feet
  • Chest pain
  • Lightheadedness
  • Dizziness
  • Heartbeats that are irregular
  • Shortness of breath

What Is Lupus?

Lupus is an autoimmune disease. In patients with lupus, the body’s immune system attacks its own organs and tissues. Inflammation due to lupus can affect a variety of different parts of the body, including:

  • Lungs
  • Heart
  • Joints
  • Brain
  • Skin
  • Blood cells
  • Kidneys

It can be difficult for doctors to diagnose lupus. Many of the symptoms of lupus are similar to those of other medical ailments. Even the most distinctive symptom of lupus, which is a facial rash in the shape of a butterfly, doesn’t occur in all cases. Lupus can be caused by drugs, infections, or, in some cases, even sunlight. Lupus has no cure, but the symptoms can be managed with medical treatments.

What Are the Symptoms of Lupus?

The symptoms of lupus can include:

  • Joint pain
  • Stiffness in the joints
  • Swelling in the joints
  • Rash on the face in the shape of a butterfly
  • Fever
  • Fatigue
  • Rashes elsewhere in the body
  • Photosensitive skin lesions
  • Headaches
  • Confusion
  • Memory loss
  • Shortness of breath
  • Chest pain
  • Dry eyes
  • Raynaud’s phenomenon – toes and fingers that turn blue or white due to stress

No two cases of lupus are alike. Each patient with lupus experiences different combinations of symptoms. Symptoms can develop either slowly or suddenly and may be of different levels of severity. Many people experience flare-ups of the disease which consist of more severe symptoms for a period of time.

What Are the Risks of Taking Prevacid?

Like other proton pump inhibitors, Prevacid has been linked to an increased risk of the following:

  • Fractures
  • Kidney disease
  • Heart Attack
  • Stroke
  • Pneumonia

The FDA has issued warnings for some of these risks, including:

  • Bone fractures of the:
    • Hip
    • Wrist
    • Spine
  • Pneumonia
  • Bacterial infections

The FDA also warned that Prevacid, among other PPIs, could potentially interfere with other medications, especially blood thinners, reducing their effectiveness.

What Are Prevacid’s Links to Kidney Disease?

What Is Kidney Disease?

Chronic kidney disease, also called kidney failure, is the gradual failure over time of the function of the kidneys. The kidneys are the organs that filter waste out of the body and as they lose function in kidney disease patients, waste, fluid, and electrolytes can build up to dangerous levels.

What Are the Symptoms of Kidney Disease?

The symptoms of chronic kidney disease can include the following symptoms:

  • High blood pressure
  • Fatigue
  • Swelling
  • Abnormal electrolyte levels
  • Irregular heartbeat
  • Fluid in the lungs
  • Nausea
  • Vomiting
  • Not able to eat
  • Lack of urine

What Prevacid Lawsuits Are There?

There are 14,500 ongoing lawsuits against the manufacturers of Prevacid as well as other proton pump inhibitors. The plaintiffs involved in the lawsuits are suing the companies, claiming that the drug manufacturers did not sufficiently warn them of the risks. Many of these thousands of cases have been consolidated into multi-district litigation, or MDL. These lawsuits are still ongoing, so the results are not yet known.

Should these class-action lawsuits against Takeda Pharmaceuticals succeed and result in a settlement, plaintiffs could receive compensation for:

  • Pain and suffering
  • Medical costs
  • Wrongful death
  • Lost wages

Should I Consider Hiring a Prevacid Lawyer?

If you or a loved one has taken Prevacid long-term and has suffered medical complications as a result, you may have a case against Takeda Pharmaceuticals. It’s important to speak to an attorney to discuss your case. Although studies have shown links between Prevacid and medical conditions such as kidney disease and the FDA has warned against such risks, there’s no guarantee for any case. However, a consultation with Seeger Weiss is free of charge to evaluate the merits of your case.

Notwithstanding claims related to this product, the drug remains on the market.
