Famvir FAQs

What are the benefits of using Famvir?

Famvir has a fast working anti-viral action that can stop further symptoms from appearing after just one day's treatment. It's at its most effective within 24 hours of you noticing the first symptoms, and may be less effective if taken more than 72 hours later. Famvir can make outbreaks of shingles, cold sores and genital herpes go away quicker and can help calm the symptoms, so that they are much less uncomfortable.

How does it work?

The main ingredient of Famvir is famciclovir. Famciclovir is a prodrug; it only changes into its active state, penciclovir, once it is ingested. Penciclovir acts quickly to block the actions of the enzymes responsible for the duplication of viral cells that spread from one healthy cell to another. Famvir keeps the virus from overpowering your body's natural defences, giving your immune system time to fight back and drive the herpes virus back into its dormant state.

Who can use Famvir?

Famvir can be used by anyone aged 18 years or older who wants to treat the symptoms of cold sores, shingles and genital herpes. It has been proven to be especially effective in treating the herpes virus in people over 50.

Who can't use Famvir?

Although most people can use Famvir safely, there are conditions and medications with which this medication cannot be taken. You should mention to your doctor if you have any of the following conditions, as you may not be able to use this treatment: severe lactose intolerance, kidney disease or liver disease; allergies to food, preservative or dye; if you are pregnant or breastfeeding; or if you are galactose intolerant. You should also mention any medications you are taking in your consultation.

How do you take Famvir?

The dosage that you will have to take will depend on your condition, but the sooner you take it, the faster you will be able to see results.

  • To treat shingles, three Famvir 500mg tablets should be taken daily for seven days.
  • To treat cold sores, three Famvir 500mg tablets should be taken over the course of a day for seven days.
  • To treat genital herpes, a single 250mg tablet should be taken three times per day for five days to treat the initial outbreak. For a recurring outbreak two 125mg tablets should be taken twice daily for five days. As a long-term treatment, two 250mg tablets should be taken per day.

Are there any side effects?

Famvir is very well tolerated, which is why it is prescribed often to people over 50. Side effects usually tend to affect only a small number of people and they are mostly very mild and brief. The most common side effects include nausea and headache. Less than 8% of people may experience more uncommon side effects such as menstrual cramps, vomiting, diarrhoea, fatigue and cramps. Side effects usually tend to disappear within a couple of days of using this treatment.
