Famciclovir 250mg Tablets

Product Introduction

Famciclovir 250mg is an antiviral medicine used for shingles and selected herpes simplex infections, including genital herpes and cold sores. It can also be used in a planned suppressive regimen for recurrent genital herpes.

How to use

Swallow with water, with or without food. Episodic treatment works best when started promptly at the first tingling, burning or rash. Dose and course length differ between shingles, a first herpes episode, recurrence and long-term suppression; kidney impairment requires adjustment.

How it works

The body converts famciclovir to penciclovir. Its active form inhibits viral DNA polymerase in infected cells, limiting replication of susceptible herpes viruses.

Side effects

Headache, nausea, diarrhoea or dizziness may occur. Confusion, marked drowsiness or reduced urine can indicate serious adverse effects, especially with impaired kidney function. Severe rash or facial swelling requires urgent treatment.

Important information

Tell your doctor about kidney disease, pregnancy, breastfeeding or medicines affecting kidney function. Herpes can still be transmitted during treatment. New eye pain or visual symptoms with facial shingles needs urgent assessment.
