About Drysol (Aluminum Chloride)

The aluminum in this medication is thought to help reduce the amount of sweat released from the body’s sweat ducts. The process is a chemical reaction that reduces excess sweating.
What does it treat?
This medication treats a condition called hyperhidrosis, characterized by excessive sweating. Hyperhidrosis primarily affects your underarms, hands, feet or head.
What forms does it come in?
This hyperhidrosis medicine comes in two formulations: a liquid solution and a roll-on applicator. When applied to the skin, it helps control excessive sweating in areas like your armpits, hands or feet.
Drysol vs. Aluminum Chloride
