Anyone had side effects taking crestor (rosuvastatin)?

Muscle aches, etc. This is a statin drug, and like other statins, has the danger of causing rhabdomyolysis, or muscle breakdown, a severe side effect. This may be manifested by muscle aches/problems. This drug also increases he risk of diabetes, and can also be toxic to the kidneys. In fact, muscle aches/pain is a reason patients might be taken off this drug.
