The consultation for excessive sweating assessment
History-taking is very important in the treatment of excessive sweating. The following should be explored:
Is there a genetic component? ie are there others in the family who have excessive sweating?
Has the patient had treatment before?
Were they happy with treatment every time?
Did the effect of toxin injections last well?
How is the patient’s metabolism? Do they exercise? Are they very muscular? Do they have trouble putting on or losing weight?
Are there any other areas of excessive sweating, including back, underarms or feet.
Have they every had any complications with injections for excessive sweating before eg eyelid/eyebrow droop, muscle weakness or perceived increase in sweating elsewhere.
What is the patient’s occupation and hobbies? The potential complication of muscle weakness or loss of facial expression needs to be discussed in relation to these facts
Which areas of the face are most affected with the sweating
The doctor may decide to do an iodine starch test, where she will first wipe the affected area with betadine wipes and then pour some cornstarch powder in the area. This will show exactly where the sweating problem exists.
Choosing the dose for excessive sweating on the face
The doctor will assess the sweating and decide on the best dose after taking a history and examining the patient. In particular discussing with the patient re their budget.
There are a couple of options for dosage for excessive sweating of the face. A larger dose may be used, which costs about $990 or a smaller dose may be used (cost approx $680)
If the patient has a history of poor longevity, or needing high doses or wanting maximal effect, or the surface area is larger than average, then a higher dose may be suggested
If a patient has a history of complications with muscle relaxing injections, or if their budget is small or if they want a more subtle result, then a smaller dose might be chosen.
Pain relief during treatment of facial sweating
A numbing cream (eg EMLA or LMX ) will be applied to the area prior to the treatment (45 minutes prior is ideal) Glad wrap may be used over the numbing cream to increase its effect.
Ice is always used to decrease pain and to reduce the risk of bruising.

What to expect after excessive sweating of feet treatment?
The effect of the B or D will not start to occur for 2-8 days.
The maximal effect of the drug will be at 3-4 weeks, so a review should be booked if required for 3 weeks. If at that time, further treatment is necessary, it should be performed. The starch iodine test may be necessary
What if I get asymmetry of sweating or I am still sweating at some time before the 3 week point? Do I call the doctor?
No. No need to call the doctor. Sometimes asymmetry will occur because one side just comes on quicker than the other. Usually it will right itself by the time of the review appointment. If it doesn’t, then it can be treated at the review appointment. There is no point in coming in early for treatment of asymmetry.
What do I do if at 3 weeks post treatment one side is better treated than the other?
At your 3 week review appointment, this will be investigated and further treatment may be administered.
How long will the treatment last?
The answer to this is very individual and depends on the patient’s metabolism, the dose, the placement etc.
4 months would be a typical time to retreat the area
When should I have my next treatment for excessive sweating
When the sweating recurs or at 4 months, whichever occurs first
