Famciclovir 500mg Tablets
SKU GME930Product Introduction
Famciclovir 500mg 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.
Uses
- Herpes zoster (shingles)
- selected herpes simplex episodes and suppression of recurrent genital herpes.
Benefits
Can shorten an outbreak and reduce lesion-related pain and discomfort when started early. Suppressive treatment can reduce recurrences, but does not eliminate latent herpes virus.
Does famciclovir permanently cure herpes?
No. Herpes viruses can remain dormant in nerve tissue after an outbreak settles. Antiviral treatment controls viral replication but does not remove that latent infection.
Can I pass genital herpes to a partner while taking famciclovir?
Yes. Transmission can occur even when no sores are visible. Avoid sexual contact during sores or warning symptoms; barrier protection reduces but does not eliminate risk.
Can I use the same famciclovir schedule for cold sores and shingles?
No. These conditions use different dose and duration regimens. Tablet strength alone is not enough to determine the treatment schedule.
What if shingles is close to my eye?
Eye-area shingles can threaten sight. Eye redness, pain, light sensitivity or blurred vision needs urgent eye assessment, even if oral antiviral treatment has already started.
Why is famciclovir adjusted for kidney problems?
Its active metabolite is cleared mainly through the kidneys. Reduced clearance can increase exposure and the likelihood of neurologic or kidney-related adverse effects.
