Underarm sweat solution

Underarm sweating can be a normal response to heat, activity or emotion, yet some people sweat heavily without an obvious trigger. The pattern can be limited to the underarms or part of wider [Excessive Sweating](/symptoms/excessive-sweating/). A history helps separate primary sweating from sweating linked with medicines or another health issue. Skin irritation from damp clothing can add a separate problem.

Start with habits that protect the skin: wear breathable layers, change damp clothing and apply products only as directed to intact, dry skin. A clinician may suggest [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). If topical care is not enough, [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) can reduce nerve stimulation of sweat glands for a period of time. [Microwave Sweat Gland Treatment](/treatments/laser-and-energy/microwave-sweat-gland-treatment/) is another clinic-based option. Ask about irritation, tenderness, downtime and whether repeat care may be needed.

Arrange a review if sweating suddenly changes, begins during sleep, affects several body areas or comes with fever, weight change, tremor or a racing heartbeat. Seek urgent help when heavy sweating occurs with chest pressure, trouble breathing, weakness or confusion. Early review can also help when dampness is causing repeated rashes or skin breakdown.

Ask what may be driving the sweating, whether any medicine could contribute, which option suits your skin, and what practical aftercare is needed. Tell the clinician about symptoms elsewhere, sleep-related sweating and previous reactions to deodorants or treatments.
