A drug that is effective against herpesviruses.
Aciclovir is an antiviral drug that inhibits DNA synthesis in cells infected by HERPES VIRUSES, although it does not eradicate them. It is only effective if started at the onset of infection; uses include the systemic treatment of herpes simplex infections of the skin and mucous membranes (including genital herpes), as well as of varicella-zoster (chickenpox) pneumonia and encephalitis. It is also used topically in the eye. It is especially valuable for the treatment of herpes infections in those with immunodeficiency and may be required for the prevention of recurrence and for prophylaxis — indeed, it may be life-saving. Similar medications include famciclovir and valaciclovir.
There exists an antiviral medication available in various forms such as oral tablets or liquid, topical cream for skin application, eye drops, or intravenous administration. This drug is used for the treatment of viral infections including herpes simplex (cold sores), herpes zoster (shingles), and varicella zoster (chickenpox) in adults.
Aciclovir possesses the potential to serve as an indispensable remedy in the battle against encephalitis, a formidable condition characterized by brain inflammation. While its efficacy in addressing cold sores and recurrent genital herpes is notable, it is imperative to note that aciclovir, obtainable in over-the-counter ointment form, does not eradicate these ailments entirely. Nevertheless, it exerts its influence by mitigating the intensity of the associated outbreaks.
Aciclovir is generally well-tolerated, with infrequent occurrence of adverse effects. However, in rare cases, individuals may experience symptoms such as queasiness, emesis, and weariness. Additionally, it is not uncommon for localized reactions to manifest subsequent to the application of this medication on the skin.
