Botulinum toxin for hyperhidrosis of areas other than the axillae and palms/soles.

Primary hyperhidrosis (HH) commonly affects the axillae, palms, soles, face, and/or the groin. There are limited treatment options available for HH of areas other than the axillae and palms/soles. Botulinum neurotoxin-A is an effective and safe treatment option for most hyperhidrotic areas of the body. Areas that are commonly affected, such as the face and groin, and less common areas like the submammary region and gluteal cleft are discussed. Frey syndrome, compensatory sweating, and postamputation stump HH are also discussed.
