Description

Famciclovir 250 mg tablets are an antiviral medication primarily used for the treatment of infections caused by the herpes simplex virus (HSV) and varicella-zoster virus (VZV). It is commonly prescribed for conditions such as genital herpes, cold sores, and shingles (herpes zoster). Famciclovir works by inhibiting viral replication, thus reducing the severity and duration of these viral infections.

The active ingredient, famciclovir, is a prodrug that is converted in the body to its active form, penciclovir. Penciclovir interferes with the viral DNA polymerase enzyme, which is crucial for the replication of the virus. By inhibiting this enzyme, famciclovir prevents the virus from multiplying and spreading, allowing the immune system to control the infection more effectively.

Famciclovir is typically used as part of an antiviral treatment regimen and is most effective when started early in the course of an infection. It is usually taken orally in tablet form, with dosage adjusted according to the severity and type of infection being treated. While generally well tolerated, common side effects include headache, nausea, and diarrhea.
