Why is Famvir prescribed?
Famciclovir (Famvir) is prescribed alone or in combination with other medications, for the management of viral infections such as cold sores, herpes in the genitals, shingles caused by herpes zoster. It is also being used for the management of human immunodeficiency virus (HIV).
What does it do?
Famciclovir, classified as an anti-viral medication, primarily works by preventing the polymerase of the viral DNA by inhibiting herpes simplex and the varicella zoster virus with deoxyguanosine triphosphate; thus, helping the body to fight off the infections by decreasing the length and growth and spread of the virus in the body.
How should I take it?
Famvir and its generic equivalents are currently available as 125mg, 250mg and 500mg tablets that should be taken as a whole (do not split) by mouth with or without food.
The dosage strength depends on every patient’s condition and the doctor’s prescription. It is imperative that you do not self-medicate and only take this drug after consulting with your doctor or pharmacist to determine the best dosage and dosing schedule for the treatment of your condition.
What if I missed a dose?
The desired effects of prescribed medications will only be achieved if taken properly. As much as possible, strictly follow your doctor’s prescribed dosing schedule. However, if you miss a dose, take it immediately and adjust the time of your next dose depending on your doctor’s advice. Never take two doses at the same time just to make up for your missed dose.
What are the special precautions before taking Famvir?
Before taking Famciclovir, tell your doctor or pharmacist if you have any allergies to food or to the drug itself as it may contain several inactive ingredients, which can cause allergic reactions or problems.
