Our Office and Hyperhidrosis

Dr. Richards has a specific interest in treating  localized sweating and accepts direct   visits for sweating.  Other skin problems  require physician referral. OHIP covers  office visits. Your sweating problem is assessed and treatment options reviewed.

Definitions

Excess local sweating is commonly seen in the underarms, palms, soles, upper forehead and scalp, between and under the breasts, pelvic  creases, and lower back.  The cause is unknown, but it often runs in families, and may begin in children or adults.

This information is derived  from a medical literature review;-- and from our sweat  treatment experiences during the past decade. Careful reading may save you a visit, as we outline several self treatment methods. There are many advertisements for sweat care products and procedures. Advertiser self interest and experience can influence a presentation. Read critically. Speak to others who have undergone sweat treatment.

Topicals

Topicals: -Try First. Often Effective and Inexpensive. Technique Important:

Aluminum salts: Aluminium chloride or aluminium chloride hexahydrate at 1-4%, combined with deodorant, is the most common ingredient in standard under-arm anti-perspirants. Hyperhidrosis requires  greater concentrations. To minimize irritation, these stronger products are best applied at bedtime.  Be certain the skin is dry, as these products may  irritate moist skin.  If tolerated, a second application in the morning  is beneficial. Start  slowly with a low concentration and increase as tolerated.  These products  may take a few days  to take effect.

Examples are:  Xerac AC 6.5%,  Certain Dri Pads 12.5%,  Hydrosal 15% +2% salicylic acid,  Drysol 20%. A pharmacist can increase  percentages, but local irritation is limiting.  Adjust  concentration to the skin area. ie: full strength on  palms and soles but mild on the face. Gloves or Saran wrap at night, over palms and soles, increases  penetration and results.  Skin irritation can be reduced by  hydrocortisone 1% cream (non-prescription in  USA but prescription in Canada) or non-prescription  hydrocortisone ½ % cream.  

Topical glycopyrrolate( Secure Pads 1-3%):---particularly for the face. Available at www.pharmacy.ca (1-800-727-5048); 311 Sherbourne Street (at Gerrard), Toronto, Ontario, M5A 3Y1.  (Please inform us of other distributors). Studies  from Britain and  South Korea, showed  these pads to be effective for facial and scalp sweating. Several of our patients have confirmed this. Studies on other body areas are lacking.  Systemic absorption of  glycopyrrolate can occur, so read  instructions carefully ;--and read  the section below on the oral form.

Glutaraldehyde 10% aqueous for feet is available in  many  pharmacies, and can be applied to the feet by cotton swabs daily, or a few times a week. May be  effective, but it produces  brownish discolouration, which  impairs  summer use.

Systemic Treatments (pills – anticholinergics)

Acetylcholine, which is released from fine nerve endings, stimulates sweat glands to produce sweat. Glycopyrrolate pills are anti-cholinergic and help prevent this release. They work well for all local areas;- and particularly well for generalized sweating. Common side effects  (dose related) are dry mouth (the major issue), blurred vision, dilated pupils, headaches, nervousness, urinary retention, constipation, sedation, and rapid heartbeat. Continued dry mouth may increase dental cavities. Use in pregnancy has not been studied. Two recent articles suggest that  side effects are well tolerated by about 50% of patients. Some use for short-term emergency use. Chewing sugarless gum may help dryness. Take care with hot weather exercise when sweating required. Glycopyrrolate is worth a  trial!    

Glycopyrrolate has limited availability. It was  used for decades to treat stomach ulcers, but  more effective treatments replaced it. Trade names are Avert (Canada) and Robinul (USA). These non-prescription pills are available at www.pharmacy.ca in 0.5mg, 1mg, 1.5mg and 2mg tablets. Individual response  varies. Start slowly with 0.5 mg, Gradually increase to 1 to 2mg two to three times a day as tolerated. They can also be used, with care, in children. Other anti-cholinergic drugs such as prescription oxybutynin (Ditropan 5 mgms) 1-2x a day are available. Comparative articles are not available but glycopyrrolate is the most recommended.  Propanolol 5-10 mgms is sometimes used by performers and others to reduce anxiety induced sweating and tremor but it has no specific role in hyperhidrosis.

Botulinum Toxin A (Botox Therapeutic by Allergan)

Botox has revolutionized sweat treatment.—especially of the underarms.

Vials of Botox Therapeutic

Underarms (axillae)

Botox injections work well for nearly all cases of underarm sweating. Most  achieve a 90% improvement and last  an average of 5-7months. Range 3-13. The Botox injected is identical to cosmetic Botox, but is named:-- Botox Therapeutic;---drug identification number (DIN)- 01981501. Before injecting, we apply iodine, and then cornstarch to the underarms. Sweating areas turn blue  and act as an injection guide. Please do not apply an anti-perspirant before the procedure. You may return immediately to  all activities. Botox has been used for underarms  since 1997 and there are no reports of side effects at these low doses. There can be mild injection bruises. Sweating in other areas  occurs normally as before. Beneficial effects show in 1 to 4 days, and are  maximum within a week. Deodorants can be used immediately. Botox is not approved for use in pregnancy or breast feeding, or in individuals with myasthenia gravis or similar neurological problems. Can be used in older children, teens, and adults. Most patients do not require it, but if your skin is sensitive, then an icepack is applied. You can also pre-apply a numbing agent such as:-- EMLA, Benzocaine gel, Maxilene, or Xylocaine gel 2%.

One vial of Botox contains 100 units and costs about $435 plus dispensing fee (2 vials a bit less). For small underarms, one vial does both sides. Larger underarms and most men require 2 vials. Most private insurance plans cover Botox for hyperhidrosis  (OHIP does not). Prior authorization is often required and we provide an insurance form. We do not supply  Botox vials, but write a prescription for them. Neither OHIP or insurance companies cover our injection fees.  Our total injection fee for both under-arms is $225. No HST.

Palms

Botox is 90% effective for palmar sweating. One hundred units are given to each palm, but large men’s hands require 150. We use an ice pack, and then an innovative cool refrigerant; spray (about which we have written and lectured). This spray is applied to each injection site and is very helpful in reducing sensations. We perform the actual hand injection in under 2 minutes. With Botox injections of the palms, there can be temporary (weeks) unpredictable weakening of the  fine muscles, so this procedure should be performed carefully on individuals who utilize their hands for fine work (musicians, dentists etc.) or in those who perform  vigorous activities requiring strength.  Patients rarely may choose to treat only their worst hand. Our injection fee for 2 hands is $275. No HST. After 2 or 3 weeks, the occasional patient may require a 'top-up' with additional Botox. There is no charge for these injections.

Feet

Botox injections are performed  as per hands and some do well, but satisfactory results are less consistent than with hands. We do not know why failures can occur

Forehead & Scalp

Botox injections are  effective for  the upper forehead and  frontal scalp and  patients often continue with them. After Botox injections, the forehead may feel a bit tighter and occasionally there can be bruising that  lasts a few days. One vial is usually adequate. Try Secure pads first.

Pelvic area

Botox injections work well in the thigh creases. One vial adequate.

Chest, breasts and back

Botox is effective for sweating between, and under the breasts, and for the lower back

Frey’s Syndrome

Also called-- auriculotemporal syndrome or gustatory sweating.   Can be a side effect of parotid surgery, but  can also develop spontaneously. There may be flushing and/or sweating when eating.  Botox treatment has been reported by several authors to be effective.

Please try to locate  the exact  source of your sweating in order that Botox can be administered more precisely.

Please note that our injection fees are not covered by insurance companies.

Iontophoresis - For Palms and Soles

  • Palms in iontophoresis traysPalms in iontophoresis trays
  • Inontopohresis machinesInontopohresis machines

In Iontophoresis, the hands or feet are placed in plastic pans containing tap water. An electric current is passed through the water for about 20 minutes. Initially, treatments are required every 2 to 3 days.  After 2-3 weeks, the interval between treatments can be lengthened to every week or two. Patients operate equipment themselves.  If skin irritation develops, this can usually be corrected by moisturizers, a reduction in treatment current, or a prescribed cortisone cream. Some patients find iontophoresis time consuming. Anticholinergic drugs, such as 1-2mgms Avert, can be added to the water to increase effectiveness.  These drugs are absorbed and can produce side effects as described under glycopyrrolate pills.

There are a variety of machines, but the literature (and our experience) indicates excellent results with the Fischer MD-1a galvanic unit:-- www.rafischer.com.  The machine is available in Canada from West Woodbridge Surgical, telephone 416-248-2040 or 1-800-561-3766, The price is over $1000.  We are not aware of  insurance companies paying for machines. The battery operated machines are not as powerful as the Fischer machine. Iontophoresis is not approved in pregnancy or in persons with pacemakers or metal implants. Some physiotherapy facilities (hard to find) offer trial  iontophoresis treatments for a fee.

Localized Surgery for Underarm Sweating

Most underarm sweat glands are located centrally. They can be identified by the iodine cornstarch test. The overlying skin and the active underlying sweat glands are surgically removed. Surgery is usually performed under general anaesthetic. Patients will be off work for 1 to 5 days and for about 2-4 weeks if performing physical activities or active sports. Most patients achieve good results, but there is about a 7% failure rate. Compensatory sweating in other parts of the body has not been a problem. Many plastic surgeons perform this surgery and OHIP covers it. Other surgical methods include liposuction and subcutaneous curettage but these are not widely available and are not OHIP covered. I have read about the microwave machine ‘MiraDry’ by Miramar. The preliminary reports are interesting but are company funded. I await independent views and appreciate feedback

Endoscopic Thoracic Sympathectomy (ETS) for Palmar Sweating

This surgery produces dry palms but complications can occur.  About 60% get increased (compensatory) sweating in other areas. This OHIP covered surgery is a last resort  reserved for severe palmar sweating not responsive to other methods.

Odour Control

Most complaints are for feet, and less  for; underarms. Patients should seek advice from  family/friends  as to whether  there is  truly an odour;--as frequently, others do not notice it.  Air exposure, simple soap, and regular deodorants are often effective.  Achieve air exposure by shoe and sock removal,  sock changes, arm elevation, and loose  cotton clothes. Hair dryers.  Odour results from bacterial action on sweat and skin cells. Antiperspirants assist by reducing  perspiration and deodorants are fragrances  to cover up odours. There are no controlled studies but antibacterial soaps (such as Trisan) are  helpful in controlling bacteria and  thus odour. Over the counter antibiotic creams (Polysporin)  reduce bacterial action.  Talcum powders help some, but  are messy for others.  A non-prescription antibiotic powder Zeasorb may be helpful.  Aqueous glutaraldehyde (described above) can assist in foot odour control.  Some  find commercial products such as “Odour Eaters” helpful.
