How does Botox work for Hyperhidrosis?
Using tiny injections of Botox to alleviate the symptoms of hyperhidrosis is a promising approach. Research has shown that treating excessive sweating of the armpits, hands, feet, and face with Botox is safe and effective. Botox has been shown to relieve excessive sweating for patients for nearly 7 to 9 months.
When Botox is injected, it blocks the chemical messenger sent to your sympathetic nerves so it does not reach the sweat glands. Without the chemical message, the glands cannot turn on the sweating. Botox permanently blocks the nerve endings so sweat cannot be produced. Within 6-12 weeks, your body starts to produce new nerve endings. These new endings can receive the message to turn those particular sweat glands on, so mild sweating returns. Within 4-12 months, all of the new nerve endings have been produced and the chemical message can be received, turning all of the sweat glands on again. Sweating returns to normal and the treatment has finished.
Injections can be administered in relatively little time, and do not demand any restrictions in work or leisure activity (aside from refraining from intensive exercise or the use of a sauna on the day of the injections).
**Results may vary. Botox injections do not cure hyperhidrosis, rather symptoms will subside gradually (usually in about a week) and return gradually. Follow-up injections are required to maintain dryness.
