This drug can rarely cause serious reactions such as shock or anaphylaxis, so symptoms should be monitored closely during administration. Serious skin reactions can occur, so if symptoms such as rash, blisters, or peeling skin appear, administration should be stopped immediately. Blood tests may show abnormalities such as leukopenia, anemia, and thrombocytopenia, so regular testing is necessary.

Gastrointestinal side effects such as diarrhea, nausea, vomiting, and abdominal pain may rarely occur, and if severe diarrhea or bloody stools appear, immediate consultation with healthcare personnel is necessary.

It is not recommended to use this drug in infants under 1 month of age as its safety and efficacy have not been confirmed.
