1. WHAT FAMCICLOVIR PENSA IS AND WHAT IT IS USED FOR

Famciclovir Pensa is an antiviral medicine. It works by blocking the replication of viruses that cause infection.
Since viruses replicate very early in the course of an infection, you will obtain the greatest benefit by taking Famciclovir Pensa as soon as the first symptoms appear.
Famciclovir Pensa is used to treat two types of viral infections in adults:

  • Shingles (herpes zoster), which is a viral infection caused by a virus called varicella zoster (the same virus that causes chickenpox). Famciclovir Pensa prevents the virus from spreading in the body, allowing faster healing.
  • Famciclovir Pensa is also used for the treatment of herpes zoster affecting the area around the eye or the eye itself (ophthalmic zoster).
  • Genital herpes. Genital herpes is a viral infection caused by herpes simplex virus type 1 or 2. It is usually transmitted sexually. It causes blisters and burning or itching around the genitals, which may be painful. Famciclovir Pensa is used to treat genital herpes infections in adults. Patients who experience frequent episodes of genital herpes may also take Famciclovir Pensa to help prevent recurrences.

Prevention of transmission of genital herpes to other individuals
If you are taking Famciclovir Pensa for the treatment or suppression of genital herpes, or if you have previously suffered from genital herpes, you should continue to have protected sexual intercourse by using a condom.
