Receiving Botox® injections helps to control sweat, this treatment is safer and less invasive than other surgical treatments. One of the benefits of local surgery for excessive sweating is that for whatever glands are injured or removed, there is often a permanent result – the affected glands will not produce any more sweat.
Prior to administering Botox® injections, doctors will usually examine the area to see where should be located the needles. This is done by performing a Minor iodine-starch test in which they apply an iodine solution to the armpit. Botox® is applied with a fine needle into several spots in each armpit. The injections are uncomfortable, but with a very small needle makes them tolerable. When sweat accumulates it makes a dark color in the skin, which contrasts with the color of the iodine solution. This allows the doctor where the injections should be placed. After the test is done the doctor will apply a topical anesthetic to prevent pain. Botox® is usually applied at this point, usually takes between 10 and 20 intradermal injections in each armpit to achieve proper results.
Recovery is usually a couple of days although patients may feel sore for up to a week and need to limit their arm activity (sports, lifting above their heads, etc.) during that time.
The effects usually occur between 2 and 4 days after the injections take place. The patient should notice a significant reduction of sweating. Since there is no downtime or specified recovery period, most patients are able to immediately resume their normal activities.
