Infants and children must use this medication with special caution and it should be used only to the minimum extent necessary. Elderly patients are likely to have impaired kidney function, which can lead to prolonged retention of the medication in the body, so careful adjustment of dosage and administration intervals is required. During the use of this medication, severe allergic reactions such as shock may occur infrequently; if symptoms such as hypotension, respiratory distress, or chest tightness occur, the medication should be stopped immediately and medical consultation sought. Skin rash, fever, blisters, hives, and other symptoms may occur, so if any of these symptoms arise, stop taking the medication and receive appropriate treatment.

Neuropsychiatric symptoms such as confusion, drowsiness, hallucinations, and seizures may manifest, especially in elderly patients or those with impaired kidney function. Kidney-related side effects such as worsening kidney function, hematuria, and proteinuria may occur, so it is necessary to regularly monitor kidney status. Blood abnormalities may manifest as anemia, changes in white blood cell count, and bleeding; any abnormal symptoms should be promptly reported. Hepatitis and jaundice may indicate liver dysfunction, which may necessitate liver function tests. Gastrointestinal side effects may include gastritis, nausea, vomiting, and diarrhea, and if symptoms are severe, medication should be discontinued. Fatigue, fever, muscle pain, and joint pain may occur, requiring careful observation of overall health. Arrhythmias and changes in blood pressure may occur, so if such symptoms arise, consulting with medical personnel is advised. Ureteral obstruction or urinary difficulties may rarely occur, and any abnormalities should be reported immediately.
