Famciclovir Tablets: Systemic Antiviral for Feline Herpesvirus

Famciclovir is an Antiviral medication that helps manage infections caused by DNA viruses. While originally approved for human use, it has become a vital treatment in veterinary medicine, used on an extra-label basis primarily for cats. Famciclovir is a "prodrug," meaning it is converted by the body into its active form, penciclovir, which inhibits the virus's ability to replicate. This makes it particularly effective at reducing the severity of symptoms and the duration of viral shedding during active infections.

Prescription Required

Famciclovir is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. Professional veterinary oversight is essential to determine the appropriate dosage and treatment length, as these can vary significantly based on the severity of the clinical signs. Your veterinarian will also monitor your pet for potential side effects, such as reduced appetite or gastrointestinal upset, and may suggest specific monitoring for cats with pre-existing kidney conditions.
