100 Units

Sweating is a normal bodily function. It helps regulate body temperature, particularly when the body begins to overheat during exercise or in hot weather. However, some people sweat outside of these conditions. Sometimes, when severe and persistent, this is known as hyperhidrosis. It comes in two forms: primary and secondary. Primary has no cause and is usually localized to a specific area. Secondary often has a cause and covers larger areas. While secondary often can be treated easily, primary frequently becomes a chronic condition. Luckily, BOTOX injections can temporarily relieve sweating. Seattle Plastic Surgery provides the best BOTOX for axillary hyperhidrosis Seattle and Tacoma offers.


As previously described, hyperhidrosis refers to when a person sweats during abnormal times. However, it typically goes a step further. Sweating often becomes an almost constant state during waking hours. In the case of primary hyperhidrosis, the sweating is localized to one part of the body. It often favors bilateral areas such as the armpits. 

Underarm hyperhidrosis–also known as axillary hyperhidrosis–causes incessant underarm sweating. People with hyperhidrosis often become limited in the colors they can wear, may find that deodorants do little to stop sweating, and may even experience rashes.

There are various treatments available for axillary hyperhidrosis. Prescription strength antiperspirants, medications, and even surgery may be considered. BOTOX injections–while better known wrinkle treatment–are effective in reducing or eliminating sweating in around 90% of hyperhidrosis patients. This makes them an attractive option for treating chronic sweating.

Affected Areas

Primary hyperhidrosis–sometimes called focal hyperhidrosis–can occur in areas other than the armpits. Though, it is unlikely to occur in two areas at the same time (if primary hyperhidrosis). Other areas that patients may experience hyperhidrosis include:

  • Hands
  • Soles of the feet
  • Face/scalp

Signs & Symptoms

While underarm sweating is the most obvious sign and symptom of axillary hyperhidrosis, sweating can cause other issues. Some of the signs or symptoms you may experience can include:

  • Sweating occurs in both armpits
  • At least one episode of sweating per week (usually lasts the entire duration of the day)
  • Lack of other symptoms that may indicate another medical condition that causes sweating
  • Started in or around puberty/young adulthood
  • Disruption of daily activities
  • Frequently stains clothing
  • Condition came on suddenly, often there is no obvious trigger (such as a medication change)
  • Nightsweats (more common with secondary hyperhidrosis)

Just completed my second appointment for Dysport and have been loving the results! The team here is phenomenal and make you feel so comfortable through the whole process.



BOTOX injections gained FDA approval for the treatment of primary axillary hyperhidrosis in 2004. Along with its many cosmetic uses, BOTOX does have several medical applications, including the treatment of chronic sweating. How does BOTOX stop sweating?

The main ingredient of BOTOX is Botulinum toxin A. This is a neurotoxin that in other forms can cause devastating paralysis. However, when concentrated in tiny doses, like BOTOX, it can temporarily and partially paralyze targeted bodily structures. During wrinkle treatment, it stops unnecessary muscle movements that cause dynamic wrinkles. 

When treating hyperhidrosis, the BOTOX is injected just beneath the skin. The injection is shallower because it only needs to reach the sweat glands and the nerves surrounding them. The BOTOX then intercepts and blocks the nerve signals to the brain that cause sweating. This treats excessive sweating and prevents it from occurring. It has been shown to be a highly effective treatment.


With no definitive cure for primary hyperhidrosis, finding an effective way to treat the condition is of utmost importance to patients. There are many benefits to using BOTOX for treating axillary hyperhidrosis. Some of the benefits of BOTOX for axillary hyperhidrosis in Seattle include:

  • Longer lasting results; often last between six and sixteen months
  • FDA approved treatment
  • Little risk and safe
  • Quick procedure
  • Reduction or cessation of armpit sweating
  • Little to no pain
  • No downtime
  • Improvement in anxiety or distress concerning the condition
  • Ability to wear all clothing without the worry of stains or embarrassment
  • Reduction in odor caused by sweating
  • Overall improvement in quality of life



Undergoing Seattle BOTOX for sweating will require a consultation with one of our injectors before treatment. During this appointment, your injector will ask about your medical history, lifestyle, and hyperhidrosis. They will discuss the treatment with you and may examine your underarms. They will then decide if you are a good candidate for axillary hyperhidrosis BOTOX injections.

If you are a good candidate, you can then schedule your injections. If not, your injector will talk to you about other options for treating your hyperhidrosis. Most people in good health and who have axillary hyperhidrosis are likely good candidates for the treatment.


Your axillary hyperhidrosis BOTOX injections will begin with your injector disinfecting your underarms with alcohol. They may then apply numbing cream. Following these two initial steps, your injector may make markings just before injecting the BOTOX.

The starting dose of BOTOX for hyperhidrosis is 100 units. In the case of axillary hyperhidrosis, this involves 50 units on one side and 50 on the other. This dosage is usually enough to significantly reduce or stop sweating. Though, rarely, additional units may be needed after the results are gauged.

Your injector will inject BOTOX across the entirety of your axilla using a fine needle. The injections tend to take less than fifteen minutes. You should remain comfortable during the procedure. Once finished with the injections, your injector will wipe away any pinpoint bleeding. Occasionally, they may apply ice to the area.

    There is not specific downtime or recovery time associated with underarm BOTOX. Your injector will likely advise you to avoid exercise or getting the area hot, such as in a hot tub. Most of the time, you can apply deodorant like normal the next morning. Some patients may experience minor side effects such as bruising and swelling. These generally resolve in under two weeks.

    Results take about two weeks to become finalized. Though, some patients see some reduction in sweating within a few days. If it is your first hyperhidrosis treatment at Seattle Plastic Surgery, your injector will likely see you after two weeks to talk about the results. You and your injector can then determine if more units are necessary.


    Does Getting BOTOX In Your Armpits Hurt?

    Since the injections do not go all the way into the muscle, BOTOX for axillary hyperhidrosis is generally not too painful. Our injectors can always use topical anesthetic if a patient requests it. The procedure is also quick, so most patients find the entire treatment easily bearable.

    Can BOTOX Help Sweating Elsewhere?

    Yes, any of the areas that experience primary hyperhidrosis can typically undergo BOTOX injections. It is common to use BOTOX to treat hyperhidrosis on the hands, feet, and face.

    Does BOTOX Treat Secondary Hyperhidrosis?

    In theory, BOTOX could probably provide relief from sweating caused by secondary hyperhidrosis. However, secondary hyperhidrosis tends to occur across larger portions of the body and sometimes the entire body. It is simply not worth it to use BOTOX across these larger areas.

    BOTOX may be able to control or reduce the sweating in certain areas, though. The best treatment for secondary hyperhidrosis is to determine the cause and work to address it. This could be treating a medical condition, switching or stopping a medication, or simply treating the sweating with oral medications.

    Will The Injections Still Reduce Sweating After They Wear Off?

    With consistent treatment, BOTOX can slowly weaken structures over time. For patients treating wrinkles, this may mean they do not need as much BOTOX, or their results last longer. This can happen with the sweat glands too. While less common, patients who frequently undergo BOTOX injections for sweating sometimes report that their results last longer with subsequent treatments. It is unlikely that BOTOX will permanently treat your sweating without touch-up injections. 

    How Much Are BOTOX For Axillary Hyperhidrosis Injections?
