Hyperhidrosis (Excessive Sweating)

What is Hyperhidrosis (Excessive Sweating) Treatment?

Hyperhidrosis is excessive sweating that isn’t usually linked to heat or exercise. Perspiration can get so bad that it drops off your palms or seeps through your clothes. Excessive perspiration can ruin your day and lead to shame and social anxiety.

Hyperhidrosis treatment usually helps. It often begins with the use of antiperspirants; however, if that does not help, you may need to try different therapies.

Who is a Good Candidate for Hyperhidrosis Treatment with Botox?

Botox for hyperhidrosis works by blocking the secretion of the chemical that is responsible for activating the sweat glands. Good candidates for hyperhidrosis treatment are individuals who:

  • Experience excessive sweating that significantly impacts their daily life and self-esteem
  • Have typically tried over-the-counter antiperspirants without success and are in good health for treatment
  • At least 18 years old

How Does Hyperhidrosis Treatment Work?

Botox injections for hyperhidrosis work by blocking the release of the neurotransmitter acetylcholine, which binds with your sweat glands to signal the release of sweat.

Normally, as your body temperature rises, your neurological system triggers your sweat glands. Your body cools itself automatically in this way. However, the nerves that communicate with the sweat glands are hyperactive in those who have hyperhidrosis.

When Botox injections are directly administered into the area of your body that excessively sweats, your overactive nerves are paralyzed. When your nerves can’t signal your sweat glands, you don’t sweat.


The Botox for Hyperhidrosis Procedure

The hyperhidrosis treatment procedure involves an initial consultation with a medical professional to assess the condition. If you take blood thinners, you may be asked to stop taking this medication for a few days before your injections to prevent bruising. Please tell our medical professional about any other medications that you are taking.

You will typically be asked to wear a short-sleeved shirt and avoid shaving your armpits for 2 or 3 days prior to your appointment.

Injections don’t take long and can be completed the same day as your initial consultation. Your appointment will be about 45 minutes; however, the injections will only take 20 to 30 minutes. Our medical professional will mark your skin with ink and inject the Botox using a fine needle. You’ll receive approximately 15 to 20 injections under each underarm.

Post-Treatment Care

The following aftercare advice is important to help reduce the risk of complications, and to help achieve the best possible results from treatment.

After your Botox injections for hyperhidrosis, the skin may be red, swollen and sometimes bruised at the injection sites. This will subside usually within a few days.

  • Visible sweating when you are not exerting yourself
  • Sweat soaked clothing
  • Sweat interfering with your everyday activities
  • Skin stays wet for a long period of time
  • Frequent skin infections on the parts of your body that excessively sweat
  • Cracked or peeling skin on your feet

Patients can start to experience a difference between 2-4 days. It will take approximately 2 weeks for the Botox injections to take full effect.

Botox injections for hyperhidrosis are temporary and so more maintenance injections will be needed. For underarm sweating you will generally need injections every 7-16 months. For hands and feet, you will need them about every 6 months.
