How is Crestor a Dangerous Drug?

Crestor is a popular medication that belongs to a class of drugs called statins, which are commonly used to help lower high cholesterol. Crestor also helps prevent heart attacks, strokes, and certain cardiovascular diseases. Unfortunately, Crestor has been linked to several adverse side effects, including kidney damage, liver damage, and an increased risk for developing diabetes.

If you or someone you love was prescribed Crestor and suffered serious health issues after taking the drug, it’s important that you know your legal rights. Learn more about Crestor and find out if you have a personal injury case.

Crestor’s History

The FDA first approved the sale of Crestor in 2003, to help lower cholesterol along with diet and exercise. It can also be used to prevent various cardiovascular diseases, including heart attack and stroke. Crestor, also known by its generic name, rosuvastatin, is manufactured by AstraZeneca and belongs to a class of drugs called statins. Other popular statins include Lipitor, Zocor, and Lescol.

Crestor works by preventing enzymes in the liver from making too much cholesterol. In doing so, Crestor causes the liver to break down more cholesterol in the blood. However, this can also lead to an increase in certain liver enzymes, which cause liver damage or hepatitis. For this reason, patients are encouraged to undergo liver tests before they take Crestor.

Understanding the Risks

Individuals with liver disease and other liver problems are not encouraged to take Crestor as it could lead to an increased risk of liver damage. Despite this warning, Crestor and other statins continue to be extremely popular throughout the United States and beyond. In fact, some medical experts also say that the drug is overprescribed in general and should only be given to patients who absolutely need to lower their cholesterol. Instead, Crestor is also prescribed to those who take the medication as a preventative measure.

Although Crestor was initially linked only to mild side effects, like dizziness, stomach pains, insomnia, constipation, and headaches, it has since been linked to serious health problems.

Serious side effects of Crestor include:

  • Muscle pain and damage
  • Liver damage
  • Rhabdomyolysis (muscle tissue breakdown)
  • Cataracts
  • Kidney damage
  • Increased risk for developing Type 2 diabetes

Each of these side effects can be extremely damaging and long-lasting, but the development of Type 2 diabetes stands out as one of the most life-changing. Research has found that patients face a greater risk the higher their dosage and the longer they take Crestor. Several trials have tried to determine how often patients develop Type 2 diabetes. Although results were somewhat mixed, the research did find that those who took Crestor or other statins were 9-12% more likely to develop Type 2 diabetes than those who didn’t take the drug. As a result of these studies, the FDA required AstraZeneca to add a warning to the drug’s label, stating that Crestor could lead to an increase in blood sugar levels. The labels were updated in 2012, but the United States continues to sell Crestor and similar drugs.

If you notice any severe reactions after taking Crestor, make sure you contact your doctor immediately. Anyone who suffers harm from a dangerous drug could be eligible to seek justice and compensation from the negligent parties.
