Over-the-counter treatment for hyperhidrosis

An antiperspirant is intended to reduce sweat reaching the skin surface; a deodorant mainly addresses odour. Product strength and formulation vary, and a product that suits the underarms may irritate the face, hands, feet, or freshly shaved skin. Apply only as directed and stop if burning, swelling, or a persistent rash develops. Damp folds can become irritated and may be affected by heat rash or intertrigo, so reducing sweat is only part of skin care.

Apply to clean, completely dry, intact skin, often at a time when sweating is lower, and wash it off as directed if irritation is a concern. Avoid eyes, mucous membranes, cuts, and recently shaved skin. Wear breathable clothing and change damp garments. If a non-prescription product does not provide enough control, a clinician may suggest prescription antiperspirant, iontophoresis, botulinum toxin injections, or microwave sweat gland treatment. Do not layer several strong products without advice.

Make an appointment if sweating is new, widespread, occurs during sleep, causes skin damage, or interferes with work and everyday activities. Seek urgent help for heavy sweating with chest pain, fainting, confusion, severe breathing difficulty, or overheating. A clinician can review medicines and possible causes before recommending stronger treatment.

Which ingredient and body areas are appropriate for me? How can I prevent irritation? If this product fails, what is the next reasonable option for my pattern of sweating?
