LamisilAT products are clinically proven antifungal treatments. Featuring the active ingredient terbinafine hydrochloride 1%, LamisilAT is formulated to stay in the skin and kill the fungus, not just inhibit its growth, until it is gone. After a week of treatment, LamisilAT cream stays in your skin to provide protection for up to 3 months, relieving uncomfortable symptoms associated with athlete’s foot, jock itch and ringworm, such as itching, burning, cracking and scaling. LamisilAT is the #1 doctor recommended brand, available in both spray and cream forms.
