About Famciclovir

Medications known as antivirals such as famciclovir will help to ease the uncomfortable and often embarrassing nature of a genital herpes outbreak, whilst also reducing the severity and length of it as well.  Such treatments work on groups of similar conditions as in the case of oral and genital herpes, as well as shingles, and they can help to stop the virus being so active within the body thus potentially reducing the number of episodes a patient may experience.

The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any genital herpes treatment, including Famciclovir.

What is contained in Famciclovir?

Each tablet has the required dose of the active ingredient famciclovir along with the following inactive ingredients:

  • hydroxypropyl cellulose
  • hydroxypropyl methylcellulose
  • lactose
  • magnesium stearate
  • polyethene glycols
  • sodium starch glycolate
  • titanium dioxide.

Please let the doctor know if you are lactose intolerant.

How does Famciclovir work?

Famciclovir falls into a family of drugs known as nucleotides which are agents used against a number of viral infections, including hepatitis B and C, as well as HIV and herpes.  They are antimetabolites which incorporate into the DNA of a virus and terminate its growth pattern, thus suppressing it and slowing down the regularity or severity of outbreaks and, in some cases, stopping them altogether.

Why choose Famciclovir?

The class of drug which famciclovir is found in stops the spread of herpes in the body by preventing the virus from replicating its own DNA, which it needs to do to spread and, in turn, cause a flare-up.  Famciclovir has a longer duration of action which means that it can be taken less often and still keep the required, effective level of the active drug in the system.

Another reason Famciclovir is a good choice for many people is that it is the generic version of the original branded version.  This means it has the same bioequivalence, containing the same active substance (famciclovir) in the same dosage, with the same administration route - in this case, oral - but for a lower cost.


How long can I take Famciclovir for?

When being used to lower the severity of an outbreak, famciclovir is usually taken twice a day for one day, with the course beginning as early as possible after the first signs of an outbreak which may include a tingle or itchy sensation on the affected area.  If possible, it is best to take the first tablet within 6 hours of this initial symptom.

In patients suffering from 6 or more outbreaks a year and therefore being prescribed a suppressive dose, famciclovir is generally taken twice a day for up to a year, though this would be discussed with your GP or Click Pharmacy doctor. 

How should I take Famciclovir?

It is important to read the patient information leaflet before taking any medication and always follow the advice of your doctor.  If you have any questions or concerns before beginning the treatment, then the doctors at Click Pharmacy are at hand to speak to you online at any time.  You will be advised as to how many tablets to take each day and for how long, depending on your situation and medical condition.

Famciclovir can be taken with or without food and works best when taken evenly throughout the day, as this ensures the level of the drug remains constant in your system. 

If you find that you experience any issues from taking this medication, then contact your GP or Click Pharmacy Doctor immediately for advice.

What are the side effects of Famciclovir?

As with any medication, famciclovir can cause side effects though usually only mildly, the most common of which is a headache.  Other common side effects include nausea or sickness, pain in the abdomen, diarrhoea or bloating and dizziness. 

Rare but serious side effects which require immediate medical attention can include:

  • kidney problems such as minimal urination and swelling of the lower limbs, along with shortness of breath
  • allergic reaction symptoms, including difficulty breathing, swelling of the face, tongue or throat, hives and a rash.
  • blistering of the skin
  • jaundice
  • confusion
  • drowsiness
  • hallucinations

It is crucial you let your doctor know about any other medications you are currently taking, including complementary varieties and vitamins, as well as any allergies you may suffer from to ensure this drug is safe for you to take and to limit any possible side effects as much as possible.

Can pregnant or breastfeeding women use Famciclovir Tablets?

It is advised that pregnant or breastfeeding women do not use Famciclovir Tablets. This is because there is not enough research to suggest that Famciclovir is safe to use.
