Driclor Roll-On For Excessive Sweating is designed for the treatment of excessive perspiration (hyperhidrosis). Its active ingredient, Aluminium chloride, ensures it is an effective antiperspirant to control severe excessive sweating. It blocks the sweat glands which causes the pressure of fluid within the sweat glands to rise to the point where it shuts off sweat production. This medicine should only be used on small areas of skin, i.e the armpits, hands or feet, to ensure that no detrimental effects occur from widespread blocking of pores and obstruction of sweating. So if your problem is excessive sweating of the armpits, hands or feet, then Driclor could be the ideal product for you. **How does it work?** Aluminium chloride is an effective antiperspirant that is applied to the skin to control severe excessive sweating (hyperhidrosis).
