What are the treatment options for underarm sweating?

Axillary hyperhidrosis is sweating in the underarms that is greater than your body needs for cooling. A prescription antiperspirant is applied to the skin and works at the sweat ducts. Botulinum toxin is injected into the underarm to reduce nerve signals that activate sweat glands. Microwave sweat gland treatment uses controlled energy to target sweat glands in the treated area. A clinician may discuss whether sweating is isolated to the underarms, how much it disrupts clothing or daily activities, and whether previous products irritated your skin.

Start with a medical assessment if sweating is new, marked, or affecting work and social activities. Prescription antiperspirant may suit someone wanting a topical option, but application instructions matter because irritation can occur. Injections may be considered when topical treatment is inadequate or difficult to use consistently. Microwave treatment may be discussed when a longer-lasting reduction is desired, with treatment-area effects and aftercare explained beforehand. Do not apply products to broken or freshly shaved skin unless your clinician says it is appropriate.

Seek prompt medical advice if heavy sweating begins suddenly, occurs during sleep, affects the whole body, or comes with fever, chest discomfort, breathlessness, faintness, or unexplained weight change. These features can point to a cause that needs assessment rather than cosmetic treatment. Arrange review as well if underarm skin becomes persistently painful, cracked, swollen, or infected.

Ask which treatment matches the pattern and severity of your sweating, how the underarm skin should be prepared, what temporary effects to expect, and when improvement should be reviewed. Mention medicines, pregnancy or breastfeeding, allergies, and any history of skin reactions.
