This medication should not be used in patients who are allergic to this medication or its components. In patients with poor kidney function, this medication should be used with caution, and monitoring is needed as central nervous system symptoms may occur. It should also be administered cautiously to patients with impaired liver function, as the risk of worsening liver function may increase. In infants and children, it should be used minimally and only when necessary, especially in neonates or premature infants where safety has not been established, caution is required. Elderly patients are likely to have reduced kidney function, which may increase the concentration of this medication, therefore, careful administration with adjusted dosage and intervals is necessary. Serious allergic reactions such as anaphylactic shock may rarely occur when this medication is used; if symptoms such as low blood pressure, difficulty breathing, or chest tightness occur, administration should be stopped immediately, and appropriate treatment should be sought. Skin reactions such as rash, fever, blisters, or urticaria may occur, so if these symptoms appear, administration should be discontinued.

It is most effective to administer this medication as early as possible after disease onset, particularly starting as soon as possible after symptoms of herpes zoster or chickenpox appear. During administration, it is important to maintain adequate hydration to prevent dehydration and reduce the risk of kidney toxicity. Interactions may occur when used with other medications, so inform medical personnel of any current medications you are taking. Women who are pregnant or may become pregnant should only use this medication if the benefits outweigh the risks to the fetus.
