When is Botox for sweating recommended for sweaty palms?

Palmar hyperhidrosis means the palms produce more sweat than the body needs for cooling. Botulinum toxin temporarily interrupts nerve signals that activate sweat glands in the treated skin. A clinician places small injections across the palms, while taking care around sensitive structures. The aim is to make gripping, writing, using a phone, or meeting people more manageable. Palm injections can be uncomfortable, and temporary hand weakness or tenderness is possible, so suitability depends on your health, work, and expectations.

Keep a short record of when your palms sweat and which activities it affects. Tell the clinician about hand weakness, nerve or muscle conditions, medicines, pregnancy, prior injections, and any skin irritation. Discuss topical antiperspirants and other options before choosing injections. Ask how the treatment will be delivered, how long normal hand use may be limited, and what symptoms should prompt a review. Do not inject irritated or infected skin until it has been assessed.

Arrange medical assessment if sweating is new, affects one hand much more than the other, occurs during sleep, or comes with tremor, weight change, fever, chest symptoms, or faintness. Seek urgent help for sudden severe weakness, trouble breathing, or a rapidly spreading allergic reaction after treatment.

Ask which palm areas will be treated, how hand strength will be protected, what alternatives are available, and how you should plan work or driving after the appointment.
