Armpit Botox typically costs around $1,000 for both underarms per session. The total depends on how your provider charges (per unit or per area), where you live, and whether insurance covers part of the bill. Since the effects wear off over time, the real cost question is what you’ll spend per year, not just per visit.
What a Single Session Costs
The FDA-approved dose for excessive underarm sweating is 50 units per armpit, so 100 units total. Most clinics charge between $15 and $25 per unit, which puts a full treatment somewhere between $1,500 and $2,500 at the high end, though many providers offer a flat rate closer to $1,000 for both sides. Geographic location plays a big role: expect to pay more in major metros like New York or Los Angeles and less in smaller cities or suburban practices.
Some clinics bundle the injection fee and the cost of the Botox itself into one price, while others bill them separately. If you’re comparing quotes, ask whether the number includes both the product and the administration fee. A quote that sounds low might not include the office visit or injection charge on top of the drug cost.
How Long Results Last
Your first treatment will typically keep sweating under control for about five and a half months. That means most people need two treatments per year initially, putting annual out-of-pocket costs in the $2,000 range if you’re paying cash. There’s a meaningful upside to sticking with it, though: a study of 83 patients found that the duration of effectiveness increases with repeated injections. By the time patients had been through several rounds, the median duration stretched to eight and a half months. Over time, you may only need one to two sessions a year instead of two to three.
Insurance Coverage for Armpit Botox
When Botox is used for severe underarm sweating (a condition called primary focal hyperhidrosis), it’s classified as a medical treatment, not cosmetic. That distinction matters because medical uses can be covered by insurance. Medicare, private plans, and employer-sponsored plans all have pathways for coverage, but they require documentation of medical necessity. Your provider will need to show that you have a formal diagnosis and that you’ve tried other treatments first, like prescription antiperspirants.
Insurance companies typically require prior authorization before approving the treatment. Your doctor’s office submits clinical notes explaining why Botox is appropriate for your case, and the insurer reviews the request. If approved, your share of the cost depends on your plan’s copay or coinsurance structure. Some patients with commercial insurance end up paying very little out of pocket, especially when combined with savings programs.
Cosmetic Botox for sweating that doesn’t meet the threshold for a medical diagnosis won’t be covered. If your sweating is bothersome but not severe enough for a clinical diagnosis, you’ll pay the full amount yourself.
Savings Programs That Lower Your Cost
AbbVie, the company that makes Botox, runs a program called Botox Complete that can significantly reduce what you pay. Eligible patients with commercial insurance may pay as little as $0 per treatment, depending on their coverage and program terms. To qualify, you need to be 18 or older, receiving Botox for an FDA-approved condition like hyperhidrosis, and getting treatment in the United States. Patients on Medicare or Medicaid are not eligible for the savings offers.
If you’re uninsured or underinsured, a separate program called myAbbVie Assist may provide Botox at no cost. You’ll need to meet income requirements and work with your provider to submit an application. The manufacturer’s support line (1-800-442-6869) can walk you through both options.
What the Procedure Involves
The appointment itself is quick. A provider, typically a board-certified dermatologist, injects small amounts of Botox just 2 to 3 millimeters below the skin surface across each armpit. The injections are shallow and spread out in a grid pattern to cover the sweat gland area evenly. Most sessions take 15 to 20 minutes.
There’s no real downtime. You walk in, get the injections, and go back to your day. The most common side effects are mild bruising and minor swelling at the injection sites, both of which resolve on their own within a few days. Some people report a brief headache afterward. Serious complications are rare.
Choosing the Right Provider
Look for a provider who regularly treats hyperhidrosis with Botox, not just someone who does cosmetic injections. The technique for armpits differs from facial Botox, and experience with this specific use matters for getting even coverage across the treatment area. Board-certified dermatologists are the most common providers for this procedure, though some plastic surgeons and other specialists offer it as well.
Pricing can vary by 50% or more between providers in the same city, so it’s worth calling a few offices. When you do, ask three things: the total cost for both underarms, whether the quote includes the injection fee, and whether the office will handle insurance preauthorization if you have coverage. A good office will also help you enroll in savings programs before your first appointment.
