Botox Injections
Botulinum toxin A produces prolonged blockade of neuronal acetylcholine release at the neuromuscular junction and in cholinergic autonomic neurones. In recent years intradermal injection has been used at various sites to produce a marked reduction in sweating in hyperhidrotic areas. We only offer the service for hyperhidrosis of the axilla.

A starch iodine test is used to identify the affected area About 12 injections are given to treat each axilla.
Reduction in sweating is seen within 48 hours and the benefit will last for up to 8 months when re-injection is effective
