There are very few contraindications for ETS. It is critical that the patient fully understand all their options, including Botox, iontophoresis, and topical and oral medications. An informed consent is a critical part of a physician’s duty, as side effects like compensatory hyperhidrosis have to be clearly described.

For patients with axillary hyperhidrosis, we are cautious with patients whose main complaint is odour, as little improvement can be offered with ETS.
