from 0,4
General description of Aciclovir
Aciclovir is an antiviral medication used to treat various viral infections such as herpes simplex, herpes zoster (shingles), and varicella-zoster (chickenpox). It belongs to a class of drugs known as nucleoside analogues, which work by stopping the spread and growth of the virus in the body.
Aciclovir can be taken orally, topically, or intravenously, depending on the type and severity of the infection. It is commonly prescribed to both adults and children for the treatment of herpes infections, including genital herpes and cold sores.
According to the Centers for Disease Control and Prevention (CDC), herpes simplex virus (HSV) affects an estimated 23% of adults in the United States. The prevalence of herpes zoster, or shingles, increases with age, with nearly 1 in 3 people developing the condition in their lifetime.
| Type of Infection | Prevalence |
|---|---|
| Herpes Simplex Virus (HSV) | 23% of adults in the U.S. |
| Herpes Zoster (Shingles) | 1 in 3 people in their lifetime |
Aciclovir is generally well-tolerated, with common side effects including nausea, headache, and dizziness. It is important to follow the prescribed dosage and duration of treatment to effectively combat the viral infection and minimize the risk of viral resistance.
