Underarm treatment for sweat

The aim is to reduce troublesome moisture while keeping the underarm skin comfortable. A clinician asks whether sweating is localised, longstanding, triggered by heat or emotion, or part of [Excessive Sweating](/symptoms/excessive-sweating/) elsewhere. Sudden onset, sleep-related sweating or symptoms such as fever and palpitations can point to a need for medical evaluation before cosmetic or local treatment.

A prescription antiperspirant can reduce sweat reaching the skin when used in the instructed way; applying it to irritated or recently shaved skin may worsen discomfort. See [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) for the basics. [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) works by reducing nerve signals to treated sweat glands. [Microwave Sweat Gland Treatment](/treatments/laser-and-energy/microwave-sweat-gland-treatment/) uses targeted energy beneath the skin. Discuss temporary effects, tenderness, skin changes, aftercare and the possibility of further sessions.

Make an appointment when sweating interferes with clothing, work, sleep or social life, or when home measures have not helped. Prompt review is needed for a new change, widespread sweating, fever, unexplained weight change or medication concerns. Emergency symptoms include chest pain, severe breathlessness, collapse or confusion with sweating.

Ask which option matches your sweat pattern, how to prepare the skin, what discomfort or downtime to expect, and how results will be reviewed. Share allergies, skin conditions, pregnancy or breastfeeding, medicines and previous treatment reactions.
