Does Botox really stop sweating?

I've been suffering from hyperhidrosis ever since I was a child. Excessive sweating is a delicate subject for me, but I know I need to deal with the issue. I sweat abundantly every time I’m nervous or stressed about something. So I started researching Botox and miraDry treatments and discovered they could help me destroy problematic sweat glands. If you've had this type of procedure, please answer my thread and give me as much information as you possibly can. Please! I really need to have something done about my condition.

You may have heard the rumors that Botox injections under the armpits can aide in the reduction of excessive sweating. But is it true? The short answer is, "yes." Botox is a recommended solution for individuals over 18 years of age who experience extreme perspiration ( 

However, Botox is not the first option for these individuals. It is simply an alternative option when other topical medicines do not work. One treatment can provide relief for patients for up to 6 months. It is still unknown whether Botox produces similar results when injected somewhere other than the armpits.

The side effects of Botox for use under the armpits can also produce a wide array of risk factors. Though this solution works well for many patients, it is best to consult with your doctor or physician to discuss the particular side effects that may present themselves.

Dear User, I am sorry that you have excessive sweating. Botox (and the similar products) work by stopping a nerve from giving out its signal. For the face, it decreases the amount of signal it gives to muscles to soften the appearance of muscles and lessen wrinkles. For the armpits and hands, it can be used to decrease the signals to the sweat glands to secrete less sweat.  For sweat glands, it can decrease the output for even 6 months! 

MiraDry is another nice device for excessive sweating, and can work well for many patients. I wish you success with your sweat!

Since you’re in New York, check out a newer device called miraDry. This is supposed to help excessive sweating under the arms or armpit-related sweating you can’t control. My doctor says it’s FDA-cleared and most patients with the problem benefit from it.

Now, getting back to your original question: Yes, onobotulinumtoxin A (botox) injections can relieve hyperhidrosis. My doctor said, if your hyperhidrosis is primary, this is definitely something to try right away. She wrote that botox injections are effective for almost 87% of patients, but you can lose some sensation under the arms after injections.

If that doesn’t help, lasers are sometimes used to prevent the regrowth of your sweat glands. In a study of patients suffering from excessive underarm sweat, laser treatments worked for most patients. One study checked patients’ sweating six months after treatments. 87 of the patients said they were mostly symptom-free at that time. (The only downside I see is that your insurance might not pay for these treatments.)

Another doctor told me about endoscopic thoracic sympathectomy (ETS) to clamp the peripheral hand nerves. Controlling my sweaty hands was important because I work in an office!

Finally, if nothing else helps, ask your doctor about surgery. The sweat glands are removed from your feet, armpits, groin, armpits, etc., to remove the possibility of sweating too much.

Hope these ideas help you. I’ve been there, and know what you’re going through.

Wow! If you’ve been diagnosed with hyperhidrosis, you’re one in 367 million people! That’s five percent of the world. I have secondary hyperhidrosis from an overactive thyroid—is your condition the primary variety (when doctors don’t know what causes it)? 

Clinical strength antiperspirants work for me most of the time. I’ve also tried iontophoresis for my hands and feet. This therapy works for almost everyone who’s suffering with hyperhidrosis. Ask your doctor if he or she hasn’t already suggested it. 

If you take medication for another chronic condition, your doctor might try a new medicine to see if it helps you sweat less. My doctor prescribed an anticholinergic medicine, liquid glycopyrrolate, and I don’t know if that’s working yet. She said that beta blockers or benzodiazeprine medicines can help, too.

Why continue suffering from all that embarrassing sweat when Botox and MiraDry really can stop the agony? Botox a neurotoxin that attaches to nerve endings, blocking signals that would normally tell your body to start producing sweat. When those communications are disrupted, those messages are never delivered and you don't sweat as much as normal. This is the least invasive option, but you will need to get injects at least every six months.

I have had both. Botox works well but it's temporary. Botox works by inhibiting the synapse between your nerves and muscles (prevent acetylcholine, a neurotransmitter, from being released). By doing this, the apocrine and eccrine glands, which produce sweat, are not directed by your body to produce sweat. While Botox is very effective, it's results are only temporary and typically last 4 to 6 months. How long the botox lasts will depends on how quickly the neurotransmitters are cleared from the synapse. 

MiraDry is a non-invasive treatment, that uses electromagnetic energy (microwaves) to destroy sweat glands. With just one treatment, miraDry can reduce the amount of sweat you produce by 80-85%.

For me, miraDry was a better option than Botox. miraDry you do 1-2 times and you're done forever. With Botox, you have to return to the doctor's office frequently and it gets to be extremely costly. Botox costs $800-1,500/treatment depending on the area and amount of Botox you need. MiraDry costs $1,000-2,000 per sessions, depending on which provider you go to. I am a big fan of miraDry, but Botox is a solid, albeit, more costly alternative.
