Famvir 125mg: Uses, Benefits, Dosage, Side Effects and Safety

Famvir 125mg is an antiviral medicine and contains the active substance famciclovir. Doctors use famciclovir to treat some infections caused by herpes viruses. These include recurrent genital herpes and some other herpes-related conditions. Famvir works when the body changes famciclovir into penciclovir, which is an active antiviral compound that helps slow down the rate of viral DNA replication.

Famvir is a prescription medicine, and it is important to use it only as directed by your healthcare professional.

What is Famvir 125 mg?

Famvir 125mg is a film-coated tablet that contains famciclovir 125mg. Usually the tablet is white, round, film coated. Famciclovir is an antiviral drug. It is used to treat infections caused by certain types of viruses, including herpes simplex virus (HSV) and varicella-zoster virus (VZV).

Famvir, unlike antibiotics, does not treat infections caused by bacteria. Instead, it helps reduce the ability of susceptible herpes viruses to reproduce.

Uses Of Famvir 250mg

Doctors prescribe famciclovir to treat some herpes virus infections. Specifically, 125 mg strength is used in some treatment regimens of recurrent genital herpes. The UK product information recommends 125mg twice daily for five days for episodic treatment of recurrent genital herpes in immunocompetent adults. Lower doses may be used if dose must be adjusted for kidney function.

Famciclovir products may also be prescribed for other herpes-related conditions such as:

• Recurrent herpes genitalis
• Inhibition of recurrent genital herpes
• Shingles (herpes zoster)
• Certain recurrent oral/genital herpes infections

But the right strength and schedule of treatment depend on the particular condition. Therefore, the dose should not be titrated based on the tablet strength.

How Does Famvir 125mg Work?

Famvir contains famciclovir, which is quickly converted by the body to penciclovir. Penciclovir is converted to its active form in virus-infected cells and inhibits viral DNA synthesis. Thus, the drug can help to reduce the reproduction of viruses and the remission of herpes exacerbations.

Additionally, treatment is most effective if it is started soon after symptoms of a recurrent outbreak appear. The product information for recurrent genital herpes recommends starting treatment as soon as possible after the appearance of prodromal symptoms such as tingling, itching, burning, pain or lesions.

Famvir 125mg Dosage

The doctor will determine the dose of Famvir 125mg based on the condition being treated and the patient’s kidney function. The product information in the UK specifies a dosage of 125mg twice daily for five days for the episodic treatment of recurrent genital herpes in immunocompetent adults. Patients with markedly reduced renal function may require a different schedule.

Different dosing is essential for other herpes infections. So don’t use 125mg as a universal dose for shingles or first episode of genital herpes.

Take Famvir exactly as directed. You can take it with food or without food. If you forget to take a dose, do not take extra tablets unless your healthcare professional has told you to do so.

Famvir 125mg Side Effects

Famvir may cause side effects like other medicines. Commonly reported effects are:

• Headache
• Dizzy
• Nausea.
• Throwing up
• Stomachache.
• Diarrhoea
• Rash or Itch

Most of the reactions that are reported are mild to moderate. Rarely serious allergic or skin reactions can occur. Call your doctor right away if you have: confusion; severe dizziness; swelling of the face or throat; or serious skin reactions.

Warnings and Precautions

Tell your doctor if you have kidney problems, as this may mean the dose of famciclovir needs to be adjusted. In patients with decreased renal function, incorrect dosing may increase the risk of adverse effects including acute renal failure.

Inform your healthcare professional about any other medications you are using. Probenecid may increase levels of penciclovir, so monitoring may be necessary.

Do not take famvir if you are allergic to famciclovir, any ingredients in famvir, or penciclovir.

Genital herpes famvir 125mg

Famvir can treat recurrent genital herpes outbreaks. But antiviral treatment does not get rid of the herpes virus from the body. Patients should avoid sexual contact during an outbreak as transmission can still occur. Suppressive antiviral therapy reduces the risk of transmission but does not eliminate it. Safer sex practices are still important.
