Zocor (simvastatin) Cholesterol Lowering Drug Receives FDA Warning Due to Muscle Injuries

The U.S. Food and Drug Administration (FDA) recently announced safety label changes for the cholesterol-lowering medication simvastatin, sold in generic forms and under the brand names Zocor, Vytorin and Simcor, due to muscle concerns associated with the drug.

The FDA states that the highest approved dose – 80 milligrams – has been associated with an elevated risk of muscle injury or myopathy, particularly during the first 12 months of patient use.

New Recommendations for Zocor Use

The FDA recommends that no new patients begin taking Zocor (simvastatin) at the highest dose of the medication, 80 mg. This is because the risk of muscle injury is highest during the first year of treatment with the 80 mg dose; therefore, the FDA recommends that Zocor (simvastatin) 80 mg only be used in patients who have been taking this dose for one year or more and have not experienced any muscle toxicity.

The FDA also implemented new contraindications (specific situations in which a drug, procedure, or surgery should not be used because it may be harmful to the patient) and dose limitations for when Zocor (simvastatin) is taken with certain other medications. According to the release, “The changes to the label for simvastatin-containing medications are based on the FDA’s review of the results of the seven-year Study of the Effectiveness of Additional Reductions in Cholesterol and Homocysteine clinical trial, other clinical trial data, and analyses of adverse events submitted to the FDA’s Adverse Event Reporting System.”

The manufacturer of simvastatin, Merck, launched a website that provides additional information on the new recommendations.

How Statin Drugs Lower Cholesterol

Statin drugs lower cholesterol by decreasing its production in the liver, and are used for prevention of cardiovascular disease; according to the Centers for Disease Control and Prevention, statins are one of the most commonly prescribed medications for adults 20 and over. While studies have shown that the medication can lower the risk of having a heart attack or dying from heart disease, statin drugs have also been linked to serious side effects.

FDA Issues Zocor Muscle Injury Concerns in 2010

In August of 2008, the FDA notified the public “…of the risk of a rare condition of muscle injury called rhabdomyolysis, which can lead to kidney failure or death, when simvastatin [Zocor] is used with amiodarone.”

Concerns about increased risk of muscle injury among patients using Zocor emerged in March, 2010 when the FDA issued warnings about the risk.

According to the announcement:

“The U.S. Food and Drug Administration today warned patients and healthcare providers about the potential for increased risk of muscle injury from the cholesterol-lowering medication Zocor (simvastatin) 80 mg. Although muscle injury (called myopathy) is a known side effect with all statins, today’s warning   highlights the greater risk of developing muscle injury, including rhabdomyolysis, for patients when they are prescribed and use higher doses of this drug. Rhabdomyolysis is the most serious form of myopathy and can lead to severe kidney damage, kidney failure, and sometimes death.”

Patients taking some cholesterol-lowering medications have a greater risk of developing muscle injury, including rhabdomyolysis. While statin medications are intended to help patients, sometimes they are more harmful than helpful. If you or a loved one experienced dangerous Vytorin, Simcor, simvastatin or Zocor side effects, or have been harmed by other dangerous drugs, you may be eligible to pursue a claim or lawsuit for damages.
