Does Rosuvastatin Cause Weight Gain?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Rosuvastatin typically does not cause significant weight gain as a direct side effect. Clinical trials show that weight changes with rosuvastatin are generally minimal, with most patients experiencing less than 1-2 pounds of fluctuation. However, some people may notice slight weight changes due to improved cholesterol levels leading to increased appetite, or from lifestyle changes after starting treatment. The most common side effects of rosuvastatin include muscle pain, headache, and digestive issues rather than weight gain. If you experience unexplained weight gain while taking rosuvastatin, consult your healthcare provider to rule out other causes and evaluate whether the medication is right for you.
