How Famvir Works
Famvir works by inhibiting the replication of viral DNA, thus preventing the virus from spreading and causing further damage. Its active ingredient, famciclovir, gets converted into another chemical called penciclovir inside the body. Penciclovir then targets and inhibits the activity of the viral enzyme needed for the replication of the virus, thereby stopping it from multiplying and spreading.
“Famvir, with its unique mechanism of action, effectively suppresses and controls viral infections, providing relief to individuals suffering from the herpes simplex virus.”
Usage and Dosage
It is crucial to follow your healthcare provider’s instructions and adhere to the prescribed dosage and duration of treatment for optimal results. The dosage of Famvir may vary depending on the specific viral infection being treated, the severity of the outbreak, and individual patient factors.
The typical recommended dosage for genital herpes and herpes labialis is 1,000 mg (one tablet) twice daily for one day. For shingles, a dosage of 500 mg (half a tablet) three times daily for seven days is recommended. It is important to note that these dosages are general guidelines, and your healthcare provider may adjust them based on your specific condition.
