Famvir (active ingredient: famciclovir) is a prescription antiviral medication used to treat certain infections caused by herpes viruses. It helps reduce the severity and duration of symptoms, speeds healing, and may lower the risk of complications.
Although Famvir does not cure herpes infections, it can help manage outbreaks and relieve symptoms when taken as directed.
Famvir is approved for the treatment of the following conditions in immunocompetent adults (people with a normally functioning immune system):
Famvir is used to treat herpes simplex virus (HSV) infections, including:
Genital herpes is a sexually transmitted infection caused most commonly by herpes simplex virus type 2 (HSV-2). Symptoms may include:
Famvir helps shorten the duration of outbreaks, reduce pain and discomfort, and promote faster healing of sores. It may also help reduce the frequency of future outbreaks in some people.
Cold sores are caused by herpes simplex virus type 1 (HSV-1) and usually appear on or around the lips and mouth.
Early symptoms often include:
These symptoms are followed by small, painful blisters that eventually break open and heal.
Taking Famvir at the first sign of a cold sore, such as tingling or burning, can help shorten the outbreak and speed healing.
Famvir is also used to treat acute herpes zoster (shingles) in adults.
Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains inactive in the body and can reactivate years later as shingles.
Symptoms of shingles may include:
Famvir helps reduce the severity and duration of shingles when started as soon as possible after the rash appears. Early treatment may also help reduce the risk of long-lasting nerve pain, known as postherpetic neuralgia.
Famvir belongs to a group of medications called antiviral agents, specifically nucleoside analogues.
After you take Famvir, your body converts it into its active form, penciclovir. This active medication works by blocking the herpes viruses from making copies of themselves, preventing them from multiplying and spreading.
By slowing the growth of the virus, Famvir helps:
Because Famvir does not eliminate the herpes virus from your body, future outbreaks may still occur. Taking the medication as soon as symptoms begin gives it the best chance to work effectively and helps achieve the greatest benefit.
Famvir tablets should be taken by mouth exactly as prescribed by your healthcare provider. The tablets may be taken with or without food and should be swallowed whole with a full glass of water.
Depending on the condition being treated, Famvir may be taken once, twice, or three times a day. Try to take each dose at evenly spaced intervals to maintain a consistent level of the medication in your body and help it work effectively.
To avoid missing doses, consider setting reminders or following a daily dosing schedule. Continue taking Famvir for the entire prescribed course, even if your symptoms begin to improve. Stopping treatment too early may reduce the medication’s effectiveness.
Your healthcare provider will determine the appropriate dose based on:
Do not change your dose or stop taking Famvir without first consulting your healthcare provider.
Cold Sores (Herpes Labialis)
The typical adult dose for treating cold sores is 1,500 mg taken by mouth as a single dose. For the best results, take Famvir at the first sign of a cold sore, such as tingling, itching, or burning.
Recurrent Genital Herpes
For the treatment of recurrent genital herpes, the typical adult dose is 1 gram taken by mouth twice in one day (two doses total).
For suppressive therapy to help reduce the frequency of recurrent outbreaks, the usual dose is 250 mg taken by mouth twice daily.
Cold Sores or Genital Herpes in Adults with HIV
For adults with HIV infection who are treating cold sores or genital herpes, the typical dose is 500 mg taken by mouth twice daily for 7 days.
Shingles (Herpes Zoster)
For the treatment of shingles, the typical adult dose is 500 mg taken by mouth every 8 hours (three times daily) for 7 days.
Treatment should be started as soon as possible after the rash appears to help reduce the severity and duration of symptoms.
Kidney Problems
If you have kidney disease or reduced kidney function, your healthcare provider may prescribe a lower dose of Famvir or adjust how often you take it. Always follow the dosing instructions provided by your healthcare provider, as taking too much medication can increase the risk of side effects.
Famvir (Famcyclovir) is available in the following forms and strength:
Before taking Famvir, tell your healthcare provider about your complete medical history, including any allergies, medical conditions, and all medications you are taking. This information helps ensure the medication is safe and appropriate for you.
Before starting Famvir, let your healthcare provider know if you:
If you have kidney problems, your healthcare provider may need to adjust your dose to reduce the risk of side effects.
Famvir may interact with certain medications, which could affect how well the medication works or increase your risk of side effects.
Before taking Famvir, tell your healthcare provider about all prescription medications, over-the-counter medicines, vitamins, herbal products, and dietary supplements you are taking or plan to take.
If you are pregnant, planning to become pregnant, or breastfeeding, tell your healthcare provider before taking Famvir.
Famvir should generally be used during pregnancy only if the potential benefits outweigh the potential risks to the unborn baby. It is also not known whether famciclovir passes into breast milk in significant amounts. Your healthcare provider can help you decide whether treatment is appropriate if you are breastfeeding.
Like all medications, Famvir may cause side effects. The most common side effects include:
These side effects are usually mild and often improve as your body adjusts to the medication. Contact your healthcare provider if they persist, become bothersome, or worsen.
Although uncommon, Famvir can cause a serious allergic reaction.
Seek emergency medical attention immediately if you develop:
Stop taking Famvir and seek immediate medical care if any of these symptoms occur.
Famvir may cause dizziness or drowsiness in some people.
Until you know how the medication affects you, avoid driving, operating machinery, or performing activities that require alertness.
The safety and effectiveness of Famvir have not been established in children younger than 18 years of age for most approved uses.
Older adults may be more sensitive to the effects of Famvir, particularly if they have reduced kidney function. Your healthcare provider may prescribe a lower dose or monitor you more closely during treatment.
Some medications can reduce the effectiveness of hormonal contraceptives, increasing the risk of unintended pregnancy. If your healthcare provider advises that this may apply to your treatment, use an additional non-hormonal method of contraception, such as condoms, while taking Famvir and for the period recommended by your healthcare provider.
Famvir works best when it is taken at the first sign of a cold sore, such as tingling, itching, or burning. In clinical studies, cold sores treated with famciclovir typically healed in about 4 days. Starting treatment as early as possible can help shorten the duration of the outbreak and reduce symptoms.
How often you take Famvir depends on the condition being treated and the treatment plan prescribed by your healthcare provider. For a cold sore, Famvir is usually taken as a single dose. For recurrent genital herpes, it may be taken during an outbreak or as daily suppressive therapy to help reduce the frequency of future outbreaks. If you experience frequent herpes outbreaks, talk to your healthcare provider. They may recommend taking a lower dose every day to help prevent recurrences.
If you are pregnant, planning to become pregnant, or breastfeeding, tell your healthcare provider before taking Famvir. Famvir should generally be used during pregnancy only if the potential benefits outweigh the potential risks to the developing baby. It is also not known whether famciclovir passes into breast milk in significant amounts. If you are breastfeeding, your healthcare provider can help you decide whether Famvir is the right treatment for you based on your individual situation.
