Botox for Hyperhidrosis lasted for 2 months. Why did it only last 2?

Question

Two months ago (mid December 2018), I received 100 units of Botox for Hyperhidrosis, the Botox didn’t completely get rid of all sweating but, it did reduce to very little sweating. Two months down the line, it is now ineffective and I am sweating excessively again. My doctor informed me that it would last between 6-12 months, any idea why it has only lasted two? Thank you!

Two months is pretty short duration of action for axillary botox, but not unheard of. There's also a chance the injector just missed a spot where sweat glands were located.

Hi! I’m Lauren, the aesthetic provider here at Colorado Plastic Surgery Center. It sounds like you're experiencing a more severe case of hyperhidrosis, which can sometimes require a higher dose or more precise technique for optimal results. While Botox typically lasts 6–12 months for hyperhidrosis, some patients metabolize it more quickly, which may explain why your results wore off after just two months. It’s also possible that the depth of injection affected efficacy: if Botox is injected too deep, it may not target the sweat glands effectively. I’d recommend following up with your injector to reassess dosage and technique to help improve the outcome next time.

Botox for hyperhidrosis lasts around 6 months, although this can vary. It is possible that you may need more units. It is also possible that the injection technique was incorrect. We have had great success with Miradry for hyperhidrosis. Miradry uses thermal energy to safely eliminate sweat and odor glands permanently.

When I treat hyperhidrosis under the arms, I normally use 50 units of Botox for each side.  Normally, I do find that it can be effective there for 6-12 months.  There may be a couple of reasons whey your treatment was only effective for 2 months.  First, the injection technique could affect the results.  The injection needs to be done fairly superficially and not too deep.  Second, the dosage may be too low for you.  Some people do need more than others to get longer lasting results.

Thank you for sharing your excellent question. Unfortunately each patient metabolizes Botox at different rates with some getting 4+ months of results.  That said it would be important to see how many units and in what concentration you received them to get the best idea on how to proceed with future treatments.

Camille Cash, MD · Answer

People metabolize Botox at different rates, but based on the number of units injected I would expect it to last longer than two months.  It could be injector technique or the dilution of the product.  Reach out to your injector to discuss your concerns.

Jawdat Abboud, MD · Answer

It is very good question. Generally speaking Botox should last 6 months, in some case last up to 2 years. 2 months is too short, I will recommend you to talk to the doctor for further assistance.

Nicholas Gentry, MD · Answer

Botox duration for hyperhidrosis can vary. Different people metabolize botox at different rates. Some studies show 6+ months but this is not typically my experience. If you received 100 units and it only lasted 2 months, I would be curious as to depth of injection and dilution. I normally see 4-6 months and rarely use that much. I would recommend researching Miradry as it usually costs 1700-2000 and has a permanent reduction in underarm sweat and odor of 82% on average. Out of all of the treatments I do, Miradry has a terrific satisfaction rate.

Daniel Bahnmiller, DO · Answer

On average, Botox treatment for hyperhidrosis lasts around 6 months, but is metabolized at different rates.  These rates vary from 2 months to 2 years.  The other factors related to this may be depth of injections, brand of toxin and amount infected.  It would be best to discuss your results with your provider.

Joseph A. Russo, MD · Answer

generally botox for axillary hyperhydrosis last 8 months on average. If it only lasted for two months, it was either injected too deeply, or the dose was too small.
