Famvir is an oral antiviral prescription medication that is used to treat recurrent genital herpes, suppression of recurrent genital herpes, treatment of recurrent herpes simplex virus infections (genital herpes and cold sores) in HIV infected patients.
Famvir dosage depends on the treatment type. If it is episodic treatment– treatment of an outbreak of genital herpes as it occurs. The general dose of Famvir in this case is one 125mg pill, two times a day, for 5 days. In case of suppressive treatment (if you have frequent or severe outbreaks) you take one 250mg pill, two times a day, for up to 1 year to restrain the genital herpes virus and help to avoid outbreaks. In patients with herpes simplex and HIV, the dose of Famvir is 500 mg, two times a day, for 7 days. Famvir can be taken with or without a meal.
You may require dosage adjustment or special monitoring during treatment if you have a kidney disease. Do take Famvir if you are allergic to penciclovir (Denavir). Famvir is in the FDA pregnancy category B. Which means that animal–reproduction studies have not demonstrated a fatal risk but there are no controlled studies in pregnant women, or animal–reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the first trimester (and there is no evidence of a risk in later trimesters). Therefore, do not take Famvir without your doctor`s approval if you are pregnant, or likely to become pregnant.
If you miss a dose take it as soon as you remember. However, if it is nearly time for the next dose, skip the Missed Dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
