Precautions
If your symptoms do not improve within a few days, or if they become worse, check with your doctor.
The areas affected by herpes should be kept as clean and dry as possible. Also, wear loose-fitting clothing to avoid irritating the sores (blisters).
This medicine may cause some people to become dizzy, drowsy, or less alert than they are normally. If any of these side effects occur, do not drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert while you are taking famciclovir.
This medicine does not prevent the sexual transmission of genital herpes. You should avoid having sex when lesions are present to avoid infecting your partner.
