Lamisil treats fungal infections of athlete's foot and jock itch. For effective relief of the itching and burning, cracking and scaling which accompanies these conditions. Lamisil AT one percent cream should start to improve your skin condition in a few days, although full skin healing after the infection has cleared will take longer, up to four weeks, because of damage caused during infection. Lamisil AT one percent cream will continue to work even after you have stopped using it at the end of the treatment period. Even though you will not be using the cream, improvement should continue. Treatment can be helped by keeping the affected areas clean by regular washing and careful drying without rubbing. Scratching the area, although it may be itchy, could cause further damage and slow the healing process or spread the infection.
