TabletsClinical Overview
Aciclovir (Acyclovir) is a synthetic purine nucleoside analogue antiviral active against herpes simplex viruses (HSV-1 and HSV-2) and varicella-zoster virus (VZV). It is converted intracellularly by viral thymidine kinase into aciclovir monophosphate, subsequently phosphorylated into aciclovir triphosphate, which competitively inhibits viral DNA polymerase and terminates viral DNA chain elongation. Indicated for genital herpes, herpes labialis (cold sores), varicella (chickenpox), and herpes zoster (shingles).

Usage Guidelines
Take orally with or without food, spaced evenly across waking hours (e.g. every 4 hours, 5 times daily). Maintain plenty of fluid intake to prevent crystallization of the drug in the renal tubules. Complete the prescribed antiviral course.
General Administration Advice: Adhere strictly to the prescribed dosage, frequency, and treatment course. For oral medications, swallow with sufficient water. Never stop antibiotics, psychiatric medications, or antihypertensives abruptly without clinical direction.
Possible Side Effects
Common: Headache, nausea, dizziness, vomiting, mild abdominal distress, and diarrhea. Rare/Severe: Renal impairment/acute renal failure (especially with dehydration), neurotoxicity (confusion, agitation, tremors, hallucinations in renal patients), and severe hypersensitivity.
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Caution in elderly patients and those with underlying renal impairment; dosage adjustment is mandatory based on creatinine clearance. Ensure adequate systemic hydration during treatment. Consult physician before use during pregnancy or breastfeeding.
