Famvir is an effective and highly respected antiviral drug that is used to treat cold sores, genital herpes and shingles worldwide. If you are experiencing an outbreak of HSV 1 or 2 in any form Famvir can soothe and heal your current symptoms and help to prevent future outbreaks. It is simple to use and has few side effects.

What Is Famvir?

Famvir contains the active ingredient famciclovir. Famciclovir is used to treat and prevent viral infections including:

  • Genital herpes which is usually spread through sex. It causes blisters and open sores on the genitals.
  • Cold sores spread through kissing which appears on the lips and mouth
  • Shingles which is caused by the varicella-zoster virus which also causes chicken pox. Famvir can also treat shingles in the eye caused by ophthalmic zoster.

Famvir cannot cure herpes as the virus continues to live in the body after treatment and between outbreaks, but it does help to heal sores and prevent new ones from breaking out. Individuals with a weakened immune system can use Famvir to prevent viral spread to other areas of the body and prevent serious infections taking hold.

If you have frequent outbreaks of HSV in the form of genital herpes, colds sores or shingles then Famvir can help prevent further attacks.

How Does Famvir Work?

The active ingredient Famciclovir is a prodrug which means once it's in your system it becomes more powerful. Famvir once digested turns into penciclovir. This blocks and prevents the herpes virus from multiplying. Once the virus is prevented from multiplying your body is more able to fight off the outbreak.

Once your sores have healed the herpes virus will become dormant again. The next outbreak will depend on your individual health and whether you take preventative antivirals.

Famvir's benefits are:

  • Reduced healing time
  • Reduced burning, itching and tingling
  • Decrease in future outbreaks
  • Sores heal quicker
  • Fewer sores

Famvir can start to work within a day by soothing the symptoms of herpes and swiftly interfering with the virus's ability to multiply. Famvir is a tried and trusted herpes medication that considerably reduces your number of outbreaks and lessens their impact. Experiencing an outbreak of genital herpes without using an antiviral can be a distressing and uncomfortable experience. It's good practice to be ready with antivirals in case an outbreak becomes imminent.

How To Use Famvir

Using Famvir is simple. It consists of an easy to swallow course of tablets. The amount you are prescribed will depend on your type of infection, its severity and its regularity.

You should swallow the tablet whole with or without food. Dosages vary but for an outbreak of genital herpes, you will usually take a ten-day course. Do so as soon as possible, when you feel the tingling, blisters or burning sensations that advertise an approaching outbreak. If you delay taking medication the outbreak may be more severe.

Space out your doses so there is an even intake of antiviral medicine to fight the infection. An even spread will ensure the virus is continually tackled and more likely to be brought under control.

You should finish the course as prescribed to obtain the full benefits of Famvir, even if your symptoms start to improve. If you stop taking the course your symptoms are likely to re-emerge and will you will need to begin again to regain control.

In the case of prevention, for example, frequent genital herpes outbreaks, you may need to take a tablet several times a day over the course of a year. Keep taking it even if you do not experience an outbreak. If you stop having outbreaks it likely Famvir is working to prevent them.

You should not change your dose as this can lead to side effects and it will not boost Famvir's effectiveness. If you forget a dose, you can take it when you remember unless the next dose is due. Don't double up a dose if you've forgotten.

Store Famvir at room temperature away from moisture and heat. This includes hot or cold window-sills and cars left in the sun. Incorrect storage can lead to a reduction in the effectiveness of any prescription medicine, including antivirals such as Famvir.

Famvir Dosages

Your doctor will prescribe the correct amount of Famvir for your condition but generally, the dosages are:

  • Recurrent cold sores - one 500mg tablets three times a day for one week
  • Shingles - one 250mg pill three times a day for one week
  • Initial genital herpes - one 250mg tablets three times a day for five days
  • Recurrent genital herpes - two 250mgs pills per day for 3-5 days

It's possible to buy Famvir in 250mg and 500mg doses to suit your condition. Generally, genital herpes requires the lower dose, whereas for cold sores and shingles a higher dose is normally prescribed.

You may start Famvir on the lower dose as this can lead to fewer side effects, but this can be increased if you need a stronger medication. Your doctor will advise which is best for you.

Famvir includes a printed pill pack to help you remember when to take your pills. This helps when you have to take several pills each day. Busy individuals find this reminder invaluable. Ensure you follow the directional arrows to take advantage of the reminder labels.

Famvir Side Effects

All prescription medicines have the potential to cause side effects. Not every person will experience side effects from Famvir but if they do, they are often mild. Because Famvir is so beneficial in managing painful and distressing genital herpes, cold sores and shingles it is often worth persevering with the more common, non-harmful side effects. If they become intolerable or worse, you should seek medical advice.

The more common side effects of Famvir include headache, feeling sick, vomiting, abdominal pain, diarrhoea, dizziness, rash, itching and a liver function test giving abnormal results.

Uncommon side effects affecting up to 1 in 100 people include confusion, drowsiness and itchy rash. Rare side effects affecting up to 1 in 1,000 people include hallucinations (seeing or hearing things that are not really there) and palpitations (signs of abnormal heartbeat).

Rare but serious side effects can happen infrequently. The majority of users do not experience the following as they only affect 1 to 100 in every 10,000 users; severe blistering of the skin or mucous membranes of the lips, eyes, mouth, nasal passages and genitals; unexplained bruising, reddish or purplish patches on the skin or nosebleeds; facial swelling, swelling around the eyes, eyelid swelling or throat swelling; yellowing of the skin or eyes which can indicate jaundice; purple skin patches, itching, burning skin.

Cases of kidney failure have been reported when higher than recommended doses of famciclovir were administered to patients with underlying kidney problems.

A doctor is best placed to advise you on adverse side effects.
