This medication may cause gastrointestinal symptoms or neurological symptoms such as headaches, dizziness, mental confusion, and seizures; if any abnormal symptoms occur, consult a physician. Also, irregular heartbeats or severe skin reactions have been reported rarely, so attention should be paid to these symptoms. During treatment, disease progression should be closely monitored, and regular blood tests or checks for liver and kidney function should be conducted to identify any abnormalities. Particularly in elderly patients, those with chronic illnesses, and patients with weakened immune systems, there is an increased risk of infections such as pneumonia, so caution is required.
