What will happen during a treatment with Botox®, Xeomin® or Dysport®?
Using a very fine needle, your doctor will inject a small amount (1-2mls per armpit) of a solution of Botox®, Xeomin® or Dysport® into 10-15 place spread evenly in each armpit. Sometimes a dye is used to show up the areas where sweating is greatest and where the injections should be placed.

Is it painful?
The needles used are very fine so most people experience only mild discomfort. It is uncommon for pain relief to be required. A local anaesthetic may be used when treating the palms, as they are much more sensitive. This usually wears off in less than an hour.

How long does the treatment take?
Treatment time is approximately 30 minutes

How quickly will I notice an effect?
You should notice some change for the better within a week of your treatment. Different people have different responses to treatment. In a clinical trial, sweat production was reduced by 83% one week after treatment.

How many treatments will I need?
Usually just one session is required. All patients are invited to return for a follow-up appointment 2 weeks after their treatment. Very occasionally a ‘touch-up’ treatment is required: you will not be charged for this.

How long will the treatment last?
Usually between 4-7 months.

What happens if I decide to stop treatment?
The effects of Botox®, Xeomin® or Dysport® are completely reversible. If you decide not to have any further treatment there will be no lasting change in the areas treated. Sweating will gradually return to the level it was before you started treatment.

What are the possible side-effects?
Side-effects are rare, but a small number of patients experience an increase in sweating in another part of the body. This can also be controlled. Since the injection is made only into the skin, the effects of Botox®, Xeomin® or Dysport® will be limited to the nerves supplying the sweat glands. Occasionally, a very small amount of Botox®, Xeomin® or Dysport® may spread out from the injection site and affect a nearby nerve that supplies a muscle. Mild weakness of the arms may be experienced if this happens, but this does not last and gets better quickly without any treatment.

What are the other treatments for hyperhidrosis?
Aluminium chloride (‘Driclor’) is the active ingredient of some anti-perspirants. It is used in stronger solutions to treat hyperhidrosis. Treatment consists of applying the medication overnight using a roller-ball applicator and then washing it off in the morning. The effect lasts approximately 48 hours. Iontophoresis is the passage of a weak electrical current through a water bath (or ‘electrogalvanic’ bath). The area affected by sweating is immersed in water and electrically charged particles (ions) block the activity of sweat glands. The effects can last for up to 12 weeks, though this is highly variable and some patients report results lasting just a few days.
