Aciclovir (or acyclovir) injection is a prescription antiviral medication used to treat severe viral infections caused by the herpes simplex and varicella-zoster viruses. It is primarily administered intravenously (IV) for serious conditions like herpes encephalitis (viral infection of the brain), neonatal herpes, and severe infections in immunocompromised patients.
Key Indications for Aciclovir Injection
- Herpes Simplex Virus (HSV): Treats severe initial and recurrent mucosal and cutaneous herpes (HSV-1 and HSV-2) in immunocompromised individuals.
- Herpes Simplex Encephalitis: Used as the primary, first-line treatment for viral infections of the brain.
- Neonatal Herpes: Indicated for infants and newborns who contract the herpes simplex virus.
- Severe Genital Herpes: Prescribed for initial and severe clinical episodes in otherwise healthy (immunocompetent) patients.
