What Are Penciral Tablets (Famciclovir)?

Penciral is an antiviral medicine containing famciclovir, used to treat infections caused by herpes viruses. It is an oral prodrug, meaning the body converts it into its active form, penciclovir. Penciral is commonly prescribed for herpes zoster (shingles), genital herpes and cold sores (herpes labialis).

Composition and Strengths

Penciral is a film-coated tablet available in two strengths, 250mg and 500mg. Each tablet contains famciclovir USP, the active component that fights a range of viral infections.

How Penciral Works

Once absorbed, famciclovir converts to penciclovir, which inhibits viral DNA replication by competitively blocking deoxyguanosine triphosphate. It is active against herpes simplex viruses, varicella-zoster virus, Epstein-Barr virus and cytomegalovirus.

Absorption

Famciclovir is rapidly and extensively absorbed after oral dosing, with a bioavailability of about 77%. Peak plasma levels occur within roughly 45 minutes, and food does not affect the extent of absorption.

Uses

Penciral is used to treat genital herpes, cold sores (herpes labialis) and shingles (herpes zoster). Dosage and duration vary by condition and should always follow your doctor's advice.

Precautions and Interactions

Use with caution during pregnancy and breastfeeding. Tell your doctor about other medicines, particularly probenecid and raloxifene, which may interact. Penciral is contraindicated in anyone with known hypersensitivity to famciclovir or the tablet's excipients, and doses must be adjusted in patients with kidney problems. Always use it under medical supervision.

Caring for Skin During and After an Outbreak

Shingles and cold sores affect the skin, which can stay sensitive while it heals. Gentle, fragrance-free care helps. Explore sensitive-skin products, hydrating serums, soothing aloe vera, moisturisers and sunblock to protect recovering skin.
