Hyperhidrosis Botox 100u

• Underarm sweat leaves marks on your clothes and makes choosing clothes difficult
• Sweaty palms make handshakes, writing or using devices uncomfortable
• Sweaty feet make the inside of your shoes wet or slippery
• Topical antiperspirants haven’t been enough

Hyperhidrosis Botox doesn’t remove sweat glands, so sweating returns once the effect wears off. If you sweat heavily all over, examining the cause comes first.

• 01

  Where you are now, and where we start

  Where you sweat — underarms, hands or feet — and how much it disrupts your daily life

• 02

  The change you want, the impression you keep

  If you sweat all over your body or sweating has suddenly increased, other causes need to be looked at first, so we ask when it started and where it occurs.

• 03

  How it differs from similar options

  The skin of the palms and soles is thick and sensitive, so injections can be more painful than in the underarms; we explain this first.

• 04

  Health information and recovery schedule

  Rarely, injections in the hands can temporarily weaken grip, so we check whether your work involves delicate use of your hands.

Sweat glands also respond to nerve signals. Hyperhidrosis Botox reduces those signals.

Sweat glands produce sweat when they receive a signal (acetylcholine) released from nerve endings. When botulinum toxin is placed in the shallow layer of skin where the sweat glands are, this signal decreases and sweating in that area is reduced. In the US, Botox is approved for severe underarm hyperhidrosis that is not adequately managed with topical treatments, and the approved dose is 50 units per underarm. The hands and feet are areas where doctors use it on their own judgement outside that approval.

How it works

• 01

  Into the shallow layer of the skin

  It is placed not in muscle but in the shallow layer of the skin where the sweat glands are. That is why the injection points are divided into a dense grid.

• 02

  Finding where you sweat

  If needed, a test applying iodine and starch shows the sweating area by colour, and the injections are placed within it.

• 03

  The underarm dose

  The underarm dose in the US approved labelling is 50 units per side, 100 units for both. This is the same amount as the 100u used in this treatment.

• 04

  More care for hands and feet

  Injections in the palms and soles hurt more than in the underarms, and in the hands they can affect grip strength. How much can be covered with 100u is decided by looking at the size of the area.

1. 01

   Hearing about your sweating

   We hear when it started, where and in what situations you sweat, and which antiperspirants you have tried.

2. 02

   Choosing the area and coverage

   We decide on the underarms, hands or feet and mark the area where you sweat.

3. 03

   Injection and progress

   For several weeks after the injection, we look at the change in sweating and decide the next timing.

What the procedure is like

• You can go about your day as usual on the same day.
• On the day, don’t apply antiperspirant or remove hair at the injection sites, and avoid saunas as well.
• If numbness or weakness continues after hand or foot injections, let us know.

Safety & considerations

Heavy sweating may also be caused by another condition, so we check the cause first. If you lose a lot of strength after hand or foot injections, or swallowing or breathing becomes uncomfortable, contact us right away. Effect and duration vary from person to person.

1. Same day

   Needle marks

   Small bumps and redness may remain at the injection points.

2. A few days to 2 weeks

   Sweating starts to decrease

   You begin to feel that you sweat less. The timing differs from person to person.

3. Several months

   Lasting effect

   How long the reduced sweating lasts differs by area and person. (Results vary from person to person.)

4. When sweating returns

   Consultation for the next injection

   When sweating increases again, the next injection is decided then.

Which method suits you is decided by the degree and area of sweating. What QD Clinic offers is Hyperhidrosis Botox.

• Q. How much can 100u cover?

  The underarm dose in the US approved labelling is 100 units for both sides combined, so for the underarms you can think of it as covering both sides. For the hands and feet, it depends on the surface area and the extent of sweating, so we tell you during the examination. Injections in the hands can affect grip strength, so when the hands are chosen we set the area more carefully.

• Q. Are palm injections very painful?

  The palms are sensitive, so many people find them more painful than the underarms. Ways to reduce the pain are explained during the consultation. The palms and soles have thicker skin, so the injection can hurt more there, and injecting the hands can rarely weaken grip strength for a while. If your work needs delicate use of your hands, such as playing an instrument or precision work, please tell us in advance.

• Q. If underarm sweating is reduced, won’t I sweat more elsewhere?

  Among the adverse reactions in the approved labelling, increased sweating outside the underarms has been reported. If it increases enough to bother you, let us know. If you sweat all over your body or your sweating has suddenly increased recently, other causes need to be checked first, so please tell us about such changes too.

• Q. Will sweat odour also decrease?

  Some people feel there is less odour as sweating decreases, but Hyperhidrosis Botox is not a treatment for odour. If odour is your main concern, we discuss that separately. The injection does not remove sweat glands but only lowers their activity for a while, so sweating returns once the effect wears off.

• Q. Is it better to have it before summer?

  It takes a few days to about 2 weeks for sweating to start decreasing, so if a sweaty season or an important event is coming up, it’s best to have it with plenty of time to spare. How long reduced sweating lasts differs by area and by person, and the next injection is decided when sweating increases again. On the day of the injection, do not apply antiperspirant or remove hair at that spot, and avoid saunas.
