Many health professionals and Crestor lawyer advocates have warned of the dangers of Crestor side effects. The powerful statin drug, used to help lower cholesterol, has been associated with severe muscle toxicity and Crestor heart attack. Its adverse effects are especially worrisome for individuals over the age of 65 and in patients with kidney problems. Interest has been growing in the therapeutic benefits of Coenzyme Q10, a vitamin-like molecule that may mitigate some statin side effects. It remains important for any patient taking statins to discuss the risks and benefits of any therapies with their doctor.
