Sweat Treatment

Hyperhidrosis or severe sweating can affect up to 3% of the population. It can affect any part of your body, and patients typically come in to treat either their underarms, hands, chest, forehead, feet or even their whole body. Dr Garsing Wong has been a member of the International Hyperhidrosis Society since 2007. Dr Wong personally injects all his patients as opposed to some clinics that delegate this task to more junior members or nursing staff. Dr Wong feels that there is definitely an art involved to get the best treatment outcome, and sometimes the treatment needs to be combined to prescription medication for very severe cases of hyperhidrosis.

Hyperhidrosis or severe sweating can be extremely embarrassing, and will even severely limit your wardrobe to wearing only black!


The first line of treatment is always to try using antiperspirants.


For some patients, topical medication is not enough or patients can be allergic to the topical medications. There are some oral medications that can help - however side effects are common with these types of medication.


Treating hyperhidrosis (excessive sweating) with Botox® is extremely successful and safe way to treat this condition. The Botox which is often used to relax the muscles that causes wrinkles in our face, temporarily blocks the nerves in the underarm that causes sweating as well, giving a fast, effective treatment for a potentially embarrassing problem.


The treat can last up to 201 days (6.7months - source Botox prescribing information dated August 2009). Some patients find it helpful to time the treatments with Botox® in mid Spring, so that the effect can last throughout summer and into Autumn, thereby reducing the need for treatment to only once a year. For some patients, the treatment can be effectively combined with both topical and oral medication.


Does it hurt?

Topical anaesthetic is applied to the region for one hour, making the area numb. If this is not enough, then inhaled analgesic (pain relief that is breathed in) can be administered. For the hand or feet, local anaesthetic is administered to numb the sensation to the region.  After the procedure, you can drive home or return to work.

How long does it take?

You will need to put aside two hours in total, so that there is enough time to make the procedure painless.


What are the side effects?

Botox® is safe and effective. Although there may be some variations in effect for different patients, it does decrease the amount of sweating to the region effectively. However everyone has different expectations, and it is important that these are realistic. You will not completely stop all sweating in the treated area. The main side effect is that there can be bruising at the injection site.


How much does it cost?

Cost of the procedure depends on the size of the area that is needed to be treated and the severity of your symptoms. For an accurate quote, please make an appointment.
