If a prescription is appropriate, Mahimo-affiliated physicians may prescribe 20% aluminum chloride hexahydrate (Drysol), a prescription antiperspirant that works by blocking the sweat glands. Aluminum-containing antiperspirants are recommended for hyperhidrosis by the American Academy of Dermatology.

Not everyone should use Drysol. To learn more about side effects and contraindications, see “What are the side effects of hyperhidrosis treatment” below and read Important Safety Information for aluminum antiperspirant.
