Antiperspirants are the first line of treatment for hyperhidrosis. Antiperspirants with the maximum concentrations of active ingredients are available only with a prescription. Prescription antiperspirant brands include Drysol, Xerac AC, and Hypercare.
The most common active ingredient of prescription antiperspirants is Aluminum chloride hexahydrate. Aluminum chloride hexahydrate works by forming temporary plugs at the opening of sweat ducts in the skin.
How do I take it?
Try products with lower concentrations of active ingredients first. If these do not work, choose stronger products next. Using the product with the lowest effective concentration will help minimize skin irritation.
Prescription antiperspirants most often come in the form of a topical solution.
Antiperspirants are applied topically to the underarms and other areas where excessive sweating is a problem. Most prescription antiperspirants work best when applied at night before bed. To minimize skin irritation, always apply antiperspirants to completely dry skin. Use a hair dryer on a low setting to dry the skin first, if necessary. Your doctor may suggest using occlusion (covering or wrapping the area for a time after applying the medication) to enhance its effectiveness.
Antiperspirants can cause a rash or skin irritation, especially when applied to wet or broken skin, or immediately after shaving. Antiperspirants may stain clothing.
People with advanced kidney disease should discuss antiperspirant use with their doctor.
