Patients with genetic lactose intolerance may experience side effects due to lactose contained in this medication, so they should not use it. Patients with impaired liver function may have increased drug levels in their bodies, so dosage should be reduced and administered cautiously, particularly patients with severe liver impairment should not exceed 20mg per day.

This medication may cause neurological side effects such as headaches, dizziness, and drowsiness, and liver enzyme levels may increase, so treatment should be discontinued if abnormal signs occur. Common gastrointestinal side effects may include diarrhea, nausea, and abdominal pain, as well as reported allergic reactions such as skin rash or itching. In severe cases, various side effects may occur, including anaphylactic shock, cardiovascular abnormalities, blood cell reductions, muscle pain, and hair loss. Long-term use may increase the risk of fractures and electrolyte imbalances such as hypomagnesemia, requiring regular monitoring. This medication may slightly increase the risk of bacterial infections in the stomach by inhibiting gastric acid secretion, so if diarrhea persists, consult a physician.
