Patient Guide · September 2026
If you're looking into Botox for excessive underarm sweating, you've probably found that getting a straight answer on price is surprisingly hard.
Some clinics charge per unit. Some sell set packages. Some charge per vial, or an injection fee per area. And whether your extended health plan covers the drug can be the difference between a three-figure and a four-figure cost for exactly the same treatment.
A typical underarm treatment uses about 100 units of Botox in total - roughly 50 units per side. That number matters, because at clinics that charge per unit, the dose is what determines your bill.
In September 2026 we asked clinics across Victoria, Burnaby and Vancouver what they charge for underarm hyperhidrosis treatment - medical clinics, cosmetic clinics, med spas and dermatology offices. The honest picture:
Figures are from direct quotes provided by BC clinics and from prices published on clinic websites in September 2026. Not every clinic contacted would share pricing without a consultation. Prices change - confirm with any provider directly.
BOTOX® Therapeutic is a prescription drug. When a physician prescribes it for axillary hyperhidrosis - a recognized medical condition - many extended health plans cover the cost of the drug itself, dispensed through a pharmacy in your name. The clinic's charge on top of that is the injection fee: the professional service of assessing you and performing the treatment.
A clinic quoting "$12 per unit" is bundling drug and service into one out-of-pocket price. A clinic quoting an injection fee assumes the drug arrives separately, usually through your insurance. The same 100 units can therefore cost over $1,000 at one clinic and a few hundred dollars at another.
My injection fee for underarm hyperhidrosis treatment is $300. There is no consultation fee, and no referral is required.
When your extended health plan covers BOTOX® Therapeutic, the drug is billed through the pharmacy and the injection fee is typically your only out-of-pocket cost. If your plan does not cover the drug, you will know the full expected cost before deciding anything.
Often, yes - underarm hyperhidrosis has one of the longer track records of extended health coverage for therapeutic Botox.
BOTOX® Therapeutic prescribed by a physician may be covered by many extended health plans when it is being used for an eligible medical condition. Coverage varies between insurers and individual plans, so it cannot be guaranteed. When a plan covers BOTOX® Therapeutic, it is generally covering the drug itself; the injection fee is separate, and is not always covered the same way.
If you have extended health benefits, my office works with a specialty pharmacy to coordinate the prescription and insurance process. You do not need to arrange a prescription through another doctor first - the assessment, the prescription, and the insurance coordination are all handled at my practice.
Not always - and that is part of the assessment. Prescription-strength antiperspirants and other measures are reasonable first steps for many people, and heavy sweating occasionally has an underlying medical cause that should be looked for rather than treated over. If you are not sure whether what you experience is actually abnormal, Is My Sweating Normal? is a good place to start.
When sweating is focal, persistent, and interfering with daily life despite the simple measures, Botox is one of the most effective treatments available - most patients get roughly 4 to 9 months of dryness per treatment, and many treat about twice per year.
At roughly two treatments per year, your annual cost is simply twice your per-treatment cost. For a patient whose plan covers the drug, that is two injection fees. For a patient paying per unit out of pocket elsewhere, it can exceed $2,000 per year. Working this out for your specific plan is part of the consultation, before you commit to anything.
No. You can book a consultation for hyperhidrosis treatment directly - a referral is not required. There is no consultation fee, and you will know the proposed treatment plan and expected cost before deciding whether to proceed.
