Zocor is a widely prescribed anti-cholesterol drug. While the drug is quite effective in controlling cholesterol, it is one of its side-effects which is sending a scare into its millions of users. Zocor, which is a trade name for the drug Simvastatin, is part of a group of drugs known as statins or HMG CoA reductase inhibitors. The drug is not only used to combat cholesterol, it has had great success in helping people with diabetes and heart disease lower their risk of stroke, heart attack and other complications. One study even showed the drugs could help prevent dementia and Parkinson’s disease. But Zocor’s tendency to cause users to become susceptible to muscle injury has doctors and patients concerned.

Since its introduction in the 1980s Simvastatin (Zocor) has been widely praised and prescribed by the medical community. Things began to change slightly in 2008 when warnings were issued about the drug’s potential for causing liver damage. In winter of 2010 the FDA said Simvastatin (Zocor) caused muscle damage when taken in large doses or in combination with certain drugs. When the Study of the Effectiveness of Additional Reduction in Cholesterol and Homocysteine trial revealed 61 of every 1,000 users taking 80 mg doses of the drug showed evidence of muscle damage, it caused near panic.

Zocor/Simvastatin has been prescribed for so many ailments millions of people are in danger. Many who have used the drug in the past and had unexplained muscle trouble are uncertain whether the medication they were taking made them susceptible to injury. Study after study has confirmed the unshakeable link between Zocor and muscle injury, but the drug is so effective in treating so many ailments it has left patients and medical professionals in a quandary.

While doctors and researchers look for an acceptable dosage, people who have suffered muscle damage due to their use of the drug are looking for healing. Many questions remain. According to a report released by the FDA on June 9, 2011, at least 2 million people were put at risk of muscle damage. Many doctors said they had long known of the drug’s potential dangers. Zocor was Merck & Co.’s best selling drug and the world’s second most sold cholesterol drug, raking in an amazing $4.3 billion in 2005. Patients, on the other hand, are left wondering when Merck & Co knew of the drug’s adverse effect on muscle health.
