Famciclovir is the generic active ingredient, while Famvir® is a brand name associated with famciclovir.

Current UK medicine records list both Famvir 250mg film-coated tablets and a separate Famciclovir 250mg film-coated tablet product. Therefore, “Famciclovir 250mg” can appropriately describe the generic medicine, while “Famvir® 250mg” refers to the branded product.

Famciclovir has activity against herpes simplex virus and varicella-zoster virus. Clinical indications include selected episodes of genital herpes and herpes zoster.

How it works

Famciclovir is an oral prodrug of penciclovir. After absorption, it is converted to penciclovir, the active antiviral compound. Penciclovir interferes with viral DNA synthesis by inhibiting the viral DNA polymerase required for replication.

This antiviral activity helps limit multiplication of susceptible herpesviruses and can shorten or control outbreaks when treatment is started appropriately.

Famciclovir is used for certain infections caused by herpesviruses. Approved uses vary by jurisdiction, but regulatory information includes:

• First episode of genital herpes
• Recurrent genital herpes
• Suppression of recurrent genital herpes
• Herpes zoster (shingles)
• Ophthalmic herpes zoster in appropriate patients
• Selected herpesvirus infections in immunocompromised adults

The 250mg strength has an established role in some genital herpes treatment and suppressive regimens. Herpes zoster generally requires a different strength and regimen, so the tablet strength should be selected by a healthcare professional.

Famciclovir is generally well tolerated, but adverse reactions can occur.

Reported adverse effects include:

• Headache
• Nausea
• Dizziness
• Vomiting or gastrointestinal discomfort
• Confusion or other central nervous system effects, particularly in susceptible patients
• Allergic or hypersensitivity reactions

People with impaired kidney function may require an adjusted regimen, because penciclovir is primarily eliminated through the kidneys. Healthcare professionals should also review other medicines and medical conditions before prescribing famciclovir.

Famciclovir is a prescription medicine and should not be used to self-diagnose or treat an unexplained genital rash, skin lesion or other infection.
