Hyperhidrosis
Botox for Sweating That Antiperspirant Cannot Fix.
If you plan outfits around sweat marks, keep a spare shirt at work, or avoid raising your hand, that is not a hygiene problem and it is not in your head. It has a name and a treatment that works.
The short answer. Botox blocks the nerve signal that tells sweat glands to fire. For underarm hyperhidrosis it typically reduces sweating by 80 to 90 percent, starts working in about a week, and lasts four to six months. Flat rate at Navara, $1,100.
What is hyperhidrosis, actually?
Sweating far beyond what your body needs for temperature control. Primary hyperhidrosis is the common form, it usually starts in adolescence, it often runs in families, and it has nothing to do with hygiene, fitness or anxiety, although it certainly causes anxiety.
It affects roughly one in twenty people. Most never mention it to a clinician, because they assume nothing can be done.
How does Botox stop sweating?
Sweat glands are switched on by a nerve signal using acetylcholine. Botox blocks the release of that signal at the nerve ending. The gland is intact and undamaged, it simply stops receiving the instruction.
It is the same mechanism used for wrinkles, applied to a different target. It is FDA-cleared for severe primary axillary hyperhidrosis, meaning underarms, which is not true of most things marketed for sweating.
What does the appointment involve?
About thirty minutes. A grid of small injections just under the skin across each underarm. Patients describe it as a series of quick stings rather than pain, and numbing cream is available.
You go back to normal the same day. No downtime, no bandages, no restrictions beyond avoiding a workout for the rest of the day.
How long until it works and how long does it last?
Sweating usually starts reducing at day two to four, and the full effect is there by about a week to two weeks.
It lasts four to six months in the usual case, and often longer for sweating than for wrinkles. Many patients treat twice a year, and a good number find spring and autumn is enough because summer is the season that matters.

Flat rate, not per unit, so you know the cost before you book. Hyperhidrosis takes considerably more product than a cosmetic treatment, which is why per-unit pricing gets expensive and unpredictable.
Some insurance plans cover Botox for documented severe hyperhidrosis after antiperspirant has failed. We are cash-pay and do not bill insurance, but we can provide documentation if you want to submit for possible out-of-network reimbursement.
Is it worth it?
That is a personal calculation, and here is the honest version. At $1,100 twice a year it is not a small expense. What patients tell us is that they stopped buying shirts they throw away, stopped planning around it, and stopped thinking about it. For a condition that has shaped how someone dresses since they were fifteen, that tends to be the thing that matters.
