Famvir Generic  

Famciclovir is the generic name of Famvir, an antiviral medication that stops and suppresses the spreading of the herpes virus in the body and decreases symptoms of pain, burning, tingling, itching, and tenderness. It can also help the sore heal faster and prevent a new one from forming. 

Famvir Uses 

This medication is indicated to treat certain conditions listed below: 

  • Famvir for Shingles -This medication is used to treat symptoms of shingles. Shingle is caused by the same virus that causes chickenpox; people who recovered from chickenpox have the virus in a dormant status in their body; when the virus reactivates, it may travel to the nerve pathway to the skin and produce shingles that are a single stripe blister wrap around the left or the right side of the torso. 
  • Famvir for herpes labialis – This medication can also treat and suppress herpes labialis or cold sores. Red, fluid-filled blisters occur in the mouth or other facial areas caused by the herpes simplex virus. 
  • Famvir can also be used for recurrent herpes virus infection. 

Famciclovir goes to rapid biotransformation to activate its antiviral compound to treat infections and inhibit the activity of the herpes virus, such as DNA replication. This antiviral medication may relieve pain and discomfort, heal sore faster, and shorten the illness’s severity, but it does not cure genital herpes or herpes zoster. This medication should be administered within 48 hours at the first signs of the outbreak as directed by the doctor, for it will not work if the treatment is delayed. 

Famvir Dosage 

This medication is a prescription drug based on the patient’s medical condition and response to the treatment; drug interaction may affect how this medicine works; tell your doctor all the other medications you are taking. Famvir 500 mg is the highest strength available; 250 mg and 125 mg tablets are also available taken twice or thrice a day or as prescribed by the doctor without regard to food. The length of treatment, amount, and strengths of this medication vary per patient; listed here are the usual prescriptions; if given a different one, follow how it is prescribed:
