Hyperhidrosis

Hyperhidrosis means excess sweating, which is due to increased activity of sweat glands in armpits, feet or palms of hands.

What causes underarm sweating?

Excessive underarm sweating is caused when the sweat glands are over stimulated due to nerve endings. This occurs due to increased body temperature i.e. hot weather, or emotional stresses. Botulinum toxin works by blocking the release of the neurotransmitter i.e. Acetylcholine from the nerve endings.

Should I have this treatment first?

No, other treatments should be tried first, these included deodorants such as Driclor, Anhydrol Forte. Such deodorants block the sweat glands. Occasionally these deodorants can cause irritation, reddening of skin after continuous usage.

What if sweating is from hands or feet?

Botulinum toxin is not recommended first line for these areas as can be very uncomfortable to inject. Also alternative treatments such as iontophoresis have been proven to be more beneficial. Iontophoresis is a battery powered electrical device that use water. A moist pad and an electrical current are used on skin regularly.

How long does botulinum toxin injection last for underarm sweating?

This varies depending on individual but ranges from 4 to 9 months.

What happens during treatment?

The area of maximum sweating is marked. This can be identified by betadine liquid painted on area and corn flour to identify most active sweat glands. Approximately fifteen to twenty small injections are administered to area. After treatment can go back to work.

What are side- effects?

As with any injection discomfort can occur. Bruising is also common however these disappear after 7-10 days. Numbness does not occur.

Can these injections paralyse the muscles in my arms?

The risk of temporary muscle weakness is remote.
