Tell your prescriber or health care professional if your symptoms do not improve within a few days of starting famciclovir.
Drink several glasses of water a day while taking this medicine.
Keep affected area of blisters as clean and dry as possible. Wear loose-fitting clothing, and do not cover the area with an occlusive (plastic or waterproof) dressing.
