Famciclovir (Famvir)

Famciclovir is an antiviral medication used to treat herpes viruses, including genital herpes, cold sores, and shingles. It belongs to a class of drugs known as antivirals, which specifically target viral infections.

Famciclovir is a prodrug, meaning it is converted into its active form, penciclovir, in the body. Penciclovir then works by inhibiting the replication of viral DNA, which is essential for the virus to multiply and spread. This mechanism of action makes it effective in reducing the severity and duration of herpes virus symptoms.

Famciclovir is used to treat and manage both primary and recurrent herpes and varicella-zoster infections. More specifically, it can be used for:

  • Genital herpes: This is a sexually transmitted infection caused by the herpes simplex virus (HSV). Famciclovir can help reduce the pain and discomfort associated with genital herpes outbreaks and also decrease the risk of spreading the infection to others.
  • Cold sores: These are small, painful blisters that typically appear on or around the lips. They are caused by the HSV-1 virus and can be treated with famciclovir to reduce healing time.
  • Shingles: This is a viral infection caused by the varicella-zoster virus (VZV), which also causes chickenpox. Shingles typically present as a painful rash and blisters, and famciclovir can help alleviate symptoms and reduce the risk of complications such as postherpetic neuralgia, which is a persistent nerve pain that can occur after shingles.
  • Herpes outbreaks in immunocompromised patients: People with weakened immune systems, such as those with HIV or undergoing chemotherapy, are more susceptible to recurring herpes infections. Famciclovir can be used to reduce the frequency of outbreaks and manage symptoms in this population.

Famciclovir does not cure herpes, but it can help manage symptoms such as pain, itching, and discomfort. It can also decrease the risk of spreading the infection to others during an outbreak.

It is available as a tablet to be taken orally and is typically prescribed for 7-10 days. The dosage may vary depending on the specific condition being treated and the individual’s medical history.

In the United States, famciclovir is available under the following brand names:

  • Famvir

Common side effects associated with famciclovir may include:

  • Headache
  • Nausea
  • Gas
  • Stomach pain
  • Vomiting
  • Diarrhea

More serious side effects which should be reported to your healthcare provider immediately may include:

  • Confusion
  • Pain, burning, numbness, or tingling in the hands or feet
  • Swelling in your feet or ankles
  • Little or no urination
  • Shortness of breath
  • Fatigue

The above lists of possible side effects associated with famciclovir are not exhaustive and other side effects may occur. If you experience any severe or persistent side effects while taking famciclovir, it is important to contact your healthcare provider right away.

Frequently Asked Questions About Famciclovir

What Is Famciclovir Used to Treat?

Famciclovir is primarily used to treat herpes infections, including genital herpes, cold sores, and shingles. It can also be prescribed for immunocompromised patients who are more susceptible to recurring herpes outbreaks.

What Are the Most Common Side Effects of Famciclovir?

Like all medications, famciclovir may cause side effects in some individuals. The most common side effects include headaches and gastrointestinal symptoms such as nausea, diarrhea, and abdominal pain.

What Is the Typical Starting Dose of Famciclovir?

The exact dosage of famciclovir depends on the condition being treated and the individual’s medical history.

  • For genital herpes: For genital herpes, the dosage will depend on whether the medication is being used for an active outbreak, suppression therapy, or as a preventative measure. In general, the recommended dosage for an initial outbreak is 250 mg orally 3 times/day for 7–10 days.

How to Take Famciclovir?

If you take it to treat an outbreak, take it as soon as possible after the first signs of an outbreak appear. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
