To get rid of sweaty, clammy hands, Health Guidance recommends using high-strength antiperspirants containing aluminum chloride concentrate, and applying cornstarch or talcum powder to the palms to soak up sweat. You can also consult a dermatologist about getting a prescription for medications that control excessive sweating, such as Ditropan and Probanthine.
Some home remedies can help to cut down on the amount of sweating in the palms, such as keeping an absorbent towel in a pocket and wiping the hands on it when you feel that you are beginning to sweat, notes Health Guidance. Holding teabags in the hands every day for approximately 15 minutes is thought to close the pores and minimize palm sweating throughout the day. Wet wipes containing alcohol are good to carry in a purse or backpack for moments when sweating strikes; alcohol has a drying effect on skin and can help to prevent the hands from becoming too moist.
Health Guidance also recommends trying a procedure called iontopheresis, which sends electrical currents through water to lightly shock the hands' sweat glands and prohibit them from producing sweat. This is a progressive therapy and prolonged exposure eliminates the action of sweating completely. You may also benefit from trying relaxation techniques, such as meditation, yoga and focused breathing exercises, which are able to keep the body in a calm state and help to avoid nervous sweating.
