Excessive Underarm Sweating Treatment for Men

Hyperhidrosis means sweating beyond what the body needs for temperature control. Primary hyperhidrosis usually affects specific sites such as the underarms, palms or soles. Secondary hyperhidrosis is caused by something else, including thyroid problems, diabetes, infection, some medicines and, less commonly, more serious conditions.

That distinction matters, which is why this is a consultation rather than a treatment you book off a menu. Sweating that is new, one-sided, worse at night or accompanied by weight loss or fever is investigated rather than injected.

Topical treatment

Prescription-strength antiperspirant treatment is usually the first step, with instructions on how to use it correctly.

Botulinum toxin injections

Multiple small injections into the skin of the underarm reduce sweating for a period. The effect is temporary and the treatment is repeated. Session length and the plan for repeat treatment are set by your doctor at consultation.

Investigation

Where the pattern suggests a secondary cause, blood tests or further assessment come before treatment.

• Underarm sweating that soaks clothing and interferes with work or social life
• Sweating that has not responded to over-the-counter antiperspirants
• Sweating that is causing skin irritation or recurrent odour problems
• Assessment of new or unusual sweating patterns that need a cause excluded

Consultation first: pattern, triggers, duration, medicines and a review of causes that need excluding.

Where treatment is appropriate, the underarm is cleaned and mapped, and topical numbing is used where needed.

A grid of small intradermal injections is placed across the mapped area.

Aftercare is explained and a review is booked to judge the effect.

The effect on sweating is not immediate. It develops over days after treatment.

The effect is temporary and wears off, so the treatment is repeated. Results vary between individuals and cannot be guaranteed.

Pinpoint marks, mild tenderness and occasional bruising in the underarm. Most men return to normal activity immediately.

Avoid shaving the area, deodorant, sauna and heavy exercise for twenty-four hours. Report any weakness in the arm, spreading redness or unusual pain to the clinic.

This is a repeated treatment. The interval is set by how long the effect lasts for you rather than fixed in advance.

The interval before a repeat session, and whether topical treatment continues in between, are set by your doctor at review rather than fixed in advance.

What moves the cost of treatment for excessive sweating is the number of areas treated, since underarms, palms and soles differ in the dose they need, and how often repeat treatment is required.
