Safety Advice:

• Administered only under medical supervision (risk of renal toxicity – monitor renal function, ensure adequate hydration, and slow infusion).
• Contraindicated in hypersensitivity to aciclovir/valaciclovir.
• Caution in renal impairment (dose adjustment required), dehydration, elderly, or concurrent nephrotoxic drugs (e.g., NSAIDs, aminoglycosides).
• Monitor renal function (creatinine, BUN) and urine output during treatment.
• If rash, fever, confusion, reduced urine output, or jaundice occurs, stop use and seek medical care.
