Botulinum Toxin injections block the release of the neurotransmitter acetylcholine, which binds with your sweat glands to signal the release of sweat. Normally, your nervous system activates your sweat glands when your body temperature rises so that it cools down. In people with hyperhidrosis, the sweat glands are overactive.

When you receive these injections directly into the concerned area, the nerves in treated area fail to give signal to your sweat glands and hence you don’t sweat!

Armpit sweat production is found to be reduced by more than 50 percent for at least 6 months. It is also used to reduce sweating in palms and soles.

• Avoid shaving your armpits for 2 or 3 days prior to your appointment.
• If you take blood thinners, your doctor may ask you to stop for a few days before your injections to prevent bruising.
• Avoid fish oil or Vitamin E supplements or Green tea consumption a day prior to the day of treatment.
• Tell your doctor about any medications you’re taking and don’t stop taking any medications unless your doctor tells you to.

Your appointment will likely last about an hour but the injections will only take 20 to 30 minutes.

Your Doctor will mark your skin with ink and inject the Botulinum toxin just below the surface of the skin using a fine needle. You’ll receive 15 to 20 injections in the area of concern. The practitioner may give you something to prevent pain, like ice or a numbing agent. You can return to work and normal life as soon as you’re done with your Botox injections. The practitioner will likely ask you to schedule a follow-up appointment to check in and touch up any missed spots.

You can resume your normal activities immediately after receiving Botox injections. It usually takes between 2 and 4 days to notice your results and around 14 days for the injections to take full effect.

The effects of Botox are temporary, which means you’ll need more injections in the future. For underarm sweating, booster injections are generally needed every 7 to 16 months. Results may not last as long for the hands and feet, and you may need to repeat your treatment after about 6 months

You should be able to go home immediately after your procedure. Generally, little aftercare is needed. You may feel tender around the treated area for the next day or so.

Doctors often recommend avoiding deodorant or products with perfume under your arms for about 12 to 24 hours to avoid irritation. Avoiding intense exercise and hot baths for 1 to 2 days may also help.
