Important information about Famvir
How does Famvir work?
The active ingredient in Famvir is famciclovir, a nucleoside analog DNA polymerase inhibitor, which is a prodrug of penciclovir. After oral administration, famciclovir is converted in the body to penciclovir, its active form. Its mechanism of action is through inhibition of an enzyme required for viral DNA replication. By interfering with viral DNA synthesis, Famvir limits the ability of herpes zoster, herpes simplex virus types 1 (HSV-1) and 2 (HSV-2), and varicella zoster virus (VZV) to multiply, helping reduce the severity and duration of outbreaks.
How do you use Famvir?
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Famvir. However, the following is a synopsis of the general guidelines for the use of Famvir:
Famvir is taken by mouth, with or without food.
For some indications, treatment may consist of a single dose, while others require multiple doses over several days.
If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. Do not take two doses at the same time.
Famvir does not cure herpes infections and does not prevent transmission to others.
What are the side effects of Famvir?
Some mild or common side effects of Famvir seen in clinical trials include:
Headache.
Nausea.
Diarrhea.
Dizziness.
Fatigue.
Some individuals may experience serious adverse reactions while using Famvir. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
Signs of an allergic reaction such as hives, swelling of the face or throat, or difficulty breathing.
Confusion or hallucinations, particularly in elderly patients or those with kidney impairment.
Severe skin reactions.
These are not all of the possible side effects of famciclovir. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
What are the warnings or precautions for Famvir?
Before starting Famvir, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including:
Kidney disease, as dose adjustment may be required.
A weakened immune system, including HIV infection.
A history of allergic reaction to famciclovir, acyclovir, penciclovir, or similar antiviral drugs.
Rare hereditary problems such as galactose intolerance, lactase deficiency, or glucose-galactose malabsorption, as Famvir tablets contain lactose.
Are there any contraindications with Famvir?
Famvir is contraindicated in patients with known hypersensitivity to famciclovir, penciclovir, or any component of the formulation.
How long does it take Famvir to work?
Famvir begins working shortly after administration. Symptom improvement may be noticed within a few days, especially when treatment is started early. The half-life of penciclovir allows for sustained antiviral activity, but completing the prescribed course is important even if symptoms improve.
What interacts with Famvir?
When Famvir is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:
Probenecid may increase penciclovir concentrations by reducing renal excretion, potentially increasing the risk of side effects.
What doses of Famvir are available?
It is available in tablets containing 125mg, 250mg, or 500mg of famciclovir.
How do I store Famvir?
It should be stored at room temperature, away from the reach of children or pets.
Which pharmaceutical company manufactures Famvir?
Famvir is manufactured by Novartis.
Is there a generic version of Famvir?
Yes, it is available from many manufacturers of generic drugs.
How do I stop taking Famvir?
Do not stop taking Famvir before completing the prescribed course unless advised by your healthcare provider. Stopping early may reduce effectiveness.
Can Famvir be used if I am pregnant?
Famvir should be used during pregnancy only if clearly needed. Discuss potential risks and benefits with your healthcare provider.
Can Famvir be used if I am breast feeding?
It is not known whether famciclovir passes into breast milk. Your healthcare provider can help determine whether to continue breastfeeding or use an alternative treatment.
Talk to your doctor if you are already breastfeeding or if you have any plans to breastfeed. They will know or recommend what is best for you.
