Injections for hyperhidrosis

A clinician places multiple small injections into the skin of an affected area, such as the underarms, palms or soles. The medicine reduces the local nerve signal that tells sweat glands to release sweat. It does not treat every possible cause of sweating and does not replace assessment when symptoms are new or widespread.

The procedure can be uncomfortable, particularly on the palms or soles. Temporary tenderness, redness, swelling or changes in nearby muscle activity can occur, depending on the area treated. Your clinician should explain the expected local effects and alternatives.

At consultation, describe every sweating site, previous treatments, skin conditions, allergies, medicines and any neuromuscular problem. The clinician checks that the skin is suitable and maps the treatment area. Follow instructions about cleansing and aftercare, and avoid injecting through inflamed or infected skin.

Botox For Sweating is a dedicated treatment page for this approach. Other choices may include a Prescription Antiperspirant or Iontophoresis, depending on the body site and your response to earlier care.

Contact the treating clinic for worsening pain, spreading redness, marked swelling, drainage or fever after injections. Seek urgent help for trouble breathing, swallowing, widespread weakness, fainting or a severe allergic reaction. New sweating with chest discomfort, breathlessness or confusion also needs prompt medical attention.

Ask which areas can be treated, how discomfort will be managed, what local effects to expect, when normal activities can resume, how long the benefit may last for you, and what alternatives are available.
