New Research Confirms: Serious Statin Side Effects on Muscles Are Extremely Rare

New research shows that the risk of serious muscle disorders from statins is extremely low, with only about 0.04% of people having a 10-year risk above 10%. Experts urge the public to rationally assess side effects and not forgo cardiovascular protection due to rare risks.

New Research Confirms: Serious Statin Side Effects on Muscles Are Extremely Rare

Background

Statins (such as atorvastatin, rosuvastatin, and simvastatin) are among the most widely prescribed and most studied drugs in the world. Despite over 50 years of data showing their safety, up to one-third of the approximately 50 million Americans who could benefit from statins refuse to take them due to fear of side effects.

Key Findings

A study published in The Lancet Digital Health on June 25, 2026, analyzed medical records from nearly 6 million adults in the UK and found:

  • Only about 0.04% of people had a 10-year risk of serious muscle disorders above 10% while taking statins.
  • Even if that risk were increased tenfold, it would still be very small.
  • Researchers developed a new tool to help doctors predict an individual patient's risk of severe muscle problems.

Expert Opinions

Dr. Nishant Shah, a preventive cardiologist at Duke Health, said: 'Public worry about statins is greatly exaggerated.' Dr. Steve Nissen of Cleveland Clinic noted that in 40 years of practice, he has never admitted a patient for a statin-related muscle disorder. Experts emphasize that for patients with high cholesterol and a family history of heart disease, the cardiovascular benefits far outweigh the minimal risk of side effects.

Practical Advice

Most side effects are dose-related, and doctors can manage them by adjusting the dose or switching to other cholesterol-lowering drugs. Vitamin D deficiency may also exacerbate muscle soreness. The new tool allows clinicians to perform personalized risk assessments based on a patient's age, lifestyle, and health conditions.
