Excessive Sweating in Miami, FL
Diagnosing and Treating Hyperhidrosis
Hyperhidrosis treatment addresses sweating that goes well beyond what’s needed to regulate body temperature, often affecting the underarms, palms, or soles regardless of heat or activity level. Miami’s year-round heat and humidity make it especially hard for patients with this condition to find relief through everyday antiperspirants alone. Chloe Goldman, MD, FAAD evaluates the pattern and severity of a patient’s sweating before recommending treatment for excessive sweating. Each patient is approached with individualized treatment.
Why the Body Overproduces Sweat
Hyperhidrosis occurs when the nerves that trigger the sweat glands become overactive, producing sweat far beyond what the body needs for cooling. Primary hyperhidrosis has no outside trigger. Secondary hyperhidrosis has an identifiable cause, such as an underlying medical condition or medication or anxiety. Miami’s heat and humidity don’t cause the condition, but they make its effects harder to ignore year-round.
Hyperhidrosis Treatment Options
Trial of topical treatments
A prescription-strength antiperspirant applied directly to the skin, usually the first step tried for milder cases. Other topicals that work through distinct mechanisms from antiperspirants are also utilized.
Trial of oral treatments
Medication taken by mouth to reduce sweat production more broadly when topical treatment isn't enough.
Botox® or other neuromodulators
Injected directly into the affected area to block the nerve signals, with results lasting months at a time.
How Botulinum Toxin Blocks Excess Sweat
Botulinum toxin injections are FDA-approved for hyperhidrosis. Injected directly into the underarms, palms, or soles, it blocks the transmission of nerve signals. Ultimately this prevents over-activation of the sweat glands in the treated area, typically reducing sweating for 6 months per treatment. Dr. Chloe Goldman determines candidacy based on the severity and location of a patient’s hyperhidrosis before recommending this approach.
When to See a Dermatologist for Excessive Sweating
Sweating that soaks through clothing, interferes with daily activities like holding a pen or shaking hands, or doesn’t respond to prescription-strength antiperspirants is a sign that hyperhidrosis therapy beyond over-the-counter products is worth exploring. Sudden-onset excessive sweating, particularly in adulthood, also warrants evaluation to rule out an underlying medical cause.
Signs Treatment Might Help
Patients who sweat noticeably more than their peers under the same conditions.
Patients who avoid certain fabrics or activities because of visible sweating.
Patients who've already tried over-the-counter antiperspirants without relief.
Patients with sweating confined to a specific area, such as the underarms, palms, or soles, who are often excellent candidates for targeted injection therapy rather than a systemic oral medication.
Treatment timelines
Prescription Topical Treatments
Used nightly and typically show results within 1 to 2 weeks.
Oral medications
Typically work within the first few days of initiating
Injectable Neuromodulator Treatment
Takes about one to two weeks to reach full effect, and results are maintained for up to six months. Most patients tolerate injections well, with only mild, temporary discomfort at the injection sites during the treatment itself. No significant downtime is needed afterward.
Is Excessive Sweating a Medical Condition or Just Genetics?
Both. Primary hyperhidrosis often has no root cause other than individual genetics and predisposition and tends to affect specific areas like the underarms, palms, or soles, while secondary hyperhidrosis can stem from an underlying medical condition or medication or anxiety. Our providers help distinguish between the two during an evaluation, since the distinction can change which treatment path makes the most sense.
How Long Do Botox® Injections for Hyperhidrosis Last?
Results typically last 4 to 6 months per treatment, after which sweating gradually returns. Injections can be repeated to maintain results. Most patients settle into a predictable schedule of touch-up visits once they find what works for their body.
