There are several ways to treat focal hyperhidrosis

Topical Treatments

Aluminum chloride hexahydrate (Drysol®) can reduce sweating by about 50% for mild hyperhidrosis sufferers. Antiperspirants with aluminum chloride and alcohol are the most effective for reducing wetness and odour. Initially applied daily or 2-3 times a week, the effect lasts longer with consistent use. Extra-strength formulas may cause irritation and are less effective for moderate to severe hyperhidrosis.

Botulinum Toxin Type A Injections

Botulinum toxin type A (BOTOX®) is effective for moderate to severe hyperhidrosis, reducing sweating by 83% in 95% of patients. It works by blocking nerve signals to sweat glands. Underarm, face, and head treatments are typically well-tolerated, while hands and feet may require local anaesthesia. Effects last about 7 months on average, with 30% of patients experiencing relief for over a year. Side effects, like injection site pain or compensatory sweating, are rare and temporary.

Iontophoresis

Iontophoresis treats hyperhidrosis of the hands and feet by passing a low-intensity electric current through water-soaked pads to disrupt sweat glands. Initial treatments last 30 minutes per site, 4+ days a week, with maintenance needed every few weeks. While effective, it may cause skin irritation and is not recommended for underarm or facial hyperhidrosis.

Surgery

Surgery is a last resort for treating hyperhidrosis when other therapies fail. Endoscopic thoracic sympathectomy (ETS) is used for hand sweating, where nerves causing excessive sweating are cut or clipped. For underarm sweating, surgical excision of sweat glands can provide immediate relief, with reduced sweating lasting for several years. However, compensatory sweating may occur as a side effect.

FAQs

  • The level of discomfort depends on the treatment method. For Botox injections, you may feel mild pinches, but numbing creams or ice can minimise discomfort. Non-invasive treatments, like antiperspirants or medications, generally cause little to no pain.

  • Botox temporarily blocks the nerves that signal sweat glands, significantly reducing excessive sweating in the treated area. Results typically last 4 to 6 months, after which repeat treatments may be needed to maintain dryness.

  • Results vary based on the treatment used. Botox typically shows noticeable improvement within 4 to 7 days, while other treatments, like medications or iontophoresis, may take longer to show consistent results.

  • Most hyperhidrosis treatments provide temporary relief. Botox lasts 4 to 6 months, and medications require ongoing use. Surgical options like sympathectomy may offer permanent results but are generally reserved for severe cases.
