Statins, prescribed for patients with cardiovascular issues, have been known to cause potential harm, and the risks associated with these statins overweigh their benefits in millions of people. So, are statins overprescribed? This article will guide you more about how the risks associated with statins outweigh the benefits which they offer.
What Are Statins and Why Are They Prescribed?
Statins are some of the most prescribed classes of medicines for individuals who have already had a heart attack or suffered from other cardiovascular diseases in the past, and also for people who have multiple risk factors for cardiovascular events, including high cholesterol levels, high blood pressure, and diabetes.
These prescribed classes of drugs are those that include medicines with any of the following active ingredients.
- Atorvastatin. Example- Lipitor
- Pravastatin. Example- Pravachol
- Fluvastatin. Example- Lescol
- Rosuvastatin. Example- Crestor
- Simvastatin. Example- Zocor
Statins work by blocking an enzyme known as HMG-CoA reductase that aids the liver to make cholesterol.(1)
Are Statins Overprescribed? Is It That Their Risks Exceed The Benefits?
There are questions about whether statins are overprescribed. Research published in the Annals of Internal Medicine” addresses the use of statins for primary prevention of cardiovascular diseases in individuals with no history of such diseases.(2)
A recent study suggests that statins may indeed be overprescribed, as the potential dangers of these cholesterol-lowering medicines can exceed their benefits in many individuals.
Researchers have analyzed data from above forty studies on four commonly prescribed statins, Lipitor, Zocor, Pravachol, and Crestor. They analyzed the benefits and risks of statins by using a computer model. It was found that muscle weakness, diabetes, cataracts, headaches, and dysfunction of the kidney and liver were some of the possible side effects of statins.
Results, which were published in the Annals of Internal Medicine have found that the risks caused by the drug outweigh the benefits.(3)
For instance, a net benefit was not noticed in men between age of 70 years to 75 years, unless their 10-year CVD risk was at least 21%. It was also found in men in their 40-44 years age group, the benefit of statins was not higher than the risks, unless their risk was at least 14%.
It has been mentioned by Milo Puhan, a senior author of the study at the University of Zurich, that as people age, the benefits that they receive from statins diminish when compared to the harm that they cause. (4) He also said that only 15% to 20% of elderly adults must be taking these drugs, much less than the 40% under the current guidelines.
Current US guidelines recommend the prescription of statins for people who have a 10% risk of suffering from a heart attack within the next ten years, especially those with risk factors related to cardiovascular diseases, such as high blood pressure, elevated cholesterol levels, and diabetes.(5) Under these guidelines, up to 40% of elderly Americans could be prescribed statins to mitigate their risk of experiencing a cardiovascular event or developing heart disease.
NOTE: Statins should be strictly prescribed for those who have experienced a heart attack or stroke.
Final Thoughts
Given that the risks from statins often outweigh the benefits, it is essential to consult with your healthcare professional to discuss the possible side effects or risks associated with these drugs and explore potential alternatives for treating your conditions.
