This medication may cause muscle-related symptoms, so if there is severe muscle pain or weakness, or significantly elevated creatine kinase levels, the patient should immediately discontinue use and consult a physician.

If symptoms of liver dysfunction appear (e.g., jaundice, extreme fatigue, nausea, vomiting), the patient should immediately stop taking this medication and consult healthcare professionals. Elderly patients, patients with renal impairment, and alcoholic patients should be monitored carefully for side effects when taking this medication.
