Yes, there are several medications for hyperhidrosis, ranging from prescription-strength topical treatments to oral pills and injections. The right option depends on where you sweat, how severely it affects your life, and how you respond to initial treatments. Most people start with topical options and move to stronger therapies if needed.
How Hyperhidrosis Medications Work
Nearly all hyperhidrosis medications target the same basic problem: your sweat glands are being over-activated by a chemical messenger called acetylcholine. Anticholinergic drugs, which make up the majority of treatment options, block acetylcholine from reaching receptors on your sweat glands. Without that signal, the glands produce less sweat. The difference between the various medications is mostly about how they’re delivered and how much of your body they affect.
Prescription Topical Treatments
If your excessive sweating is concentrated in your underarms, topical prescriptions are typically the first step beyond regular antiperspirants. Two anticholinergic options are FDA-approved for primary axillary hyperhidrosis in adults and children aged 9 and older. Glycopyrronium tosylate (Qbrexza) comes as a pre-moistened cloth you wipe under your arms once daily. In clinical trials, about 72 to 77% of patients using it achieved at least a 50% reduction in sweat production after four weeks, compared to roughly 53% of those using a placebo cloth.
Sofpironium (Sofdra) is a newer topical anticholinergic that received FDA approval in June 2024. It works through the same mechanism and is also applied to the underarm area daily.
Before trying prescription topicals, most doctors recommend at least six weeks of a clinical-strength aluminum chloride product, such as a 20% aluminum chloride solution. These are sometimes available over the counter but are also prescribed at higher concentrations. They physically block sweat ducts rather than targeting nerve signals. The main downside is skin irritation. Applying it to dry skin at bedtime and washing it off in the morning helps, and neutralizing the area with a light dusting of baking soda can reduce stinging.
Oral Medications
When sweating affects multiple areas of the body, or when topical treatments aren’t enough, oral anticholinergics are a common next step. The two most widely prescribed are oxybutynin and glycopyrrolate. Neither is specifically FDA-approved for hyperhidrosis, but both have been used off-label for years and are considered standard options by dermatologists.
Oxybutynin, at doses of 2.5 to 10 mg per day, has been shown to reduce excessive sweating in roughly 57 to 100% of patients across studies, with a median response rate around 76%. Glycopyrrolate, typically dosed between 2 and 9 mg daily, showed excellent results in about 77% of patients in one study, with “excellent” meaning a clinically significant improvement in sweat severity.
The trade-off with oral medications is that they reduce moisture throughout your entire body, not just in the areas where you sweat excessively. Dry mouth is by far the most common complaint, affecting about 75% of people taking oxybutynin and 38% of those on glycopyrrolate. Other possible side effects include constipation, blurred vision, difficulty urinating, drowsiness, and a faster heart rate. About 10% of people on oxybutynin stop taking it because side effects become too bothersome. Starting at a low dose and increasing gradually can help your body adjust.
Botox Injections
Botulinum toxin A (Botox) is FDA-approved for severe underarm hyperhidrosis and works differently from pills or creams. Instead of blocking the chemical signal at the sweat gland, it prevents the nerve endings near the injection site from releasing acetylcholine in the first place. A doctor injects small amounts in a grid pattern across the affected area, with each injection disabling sweat production in a circle roughly 1.2 centimeters wide.
The results are dramatic but temporary. Most people experience strong sweat reduction for the first three to six months. Symptoms then gradually return over the following months, and most patients need retreatment somewhere between 6 and 12 months after their initial session. In one study tracking patients for two years, about a third still had meaningful sweat reduction at 24 months, with a subset not needing retreatment at all. Insurance coverage for Botox injections often requires documentation that you’ve tried and failed other treatments first.
When Doctors Escalate Treatment
Doctors use a four-point scale called the Hyperhidrosis Disease Severity Scale to guide treatment decisions. A score of 1 means sweating is never noticeable, while a score of 4 means it’s intolerable and constantly interferes with daily life. Prescription medications are generally considered once you’ve scored a 3 or higher, meaning sweating is barely tolerable and frequently disrupts your routine, and you’ve already tried a topical aluminum chloride product for at least six weeks without adequate relief.
The typical treatment ladder looks like this:
- First: Clinical-strength aluminum chloride antiperspirants, applied nightly for at least six weeks
- Second: Prescription topical anticholinergics (for underarm sweating) or oral anticholinergics (for sweating in multiple areas)
- Third: Botox injections for severe cases that haven’t responded to other medications
- Fourth: Surgical options, which carry more significant risks including compensatory sweating in previously unaffected body areas
Choosing Between Options
Where you sweat matters most in choosing a medication. If sweating is limited to your underarms, a topical anticholinergic applied once daily may be all you need, with a strong chance of cutting sweat production in half or more. If your palms, feet, face, or multiple areas are affected, oral medications are more practical since you can’t easily apply a topical to every problem zone.
Your tolerance for side effects also plays a role. Topical treatments keep the medication more localized, so dry mouth and other whole-body effects are less pronounced than with pills. Botox avoids systemic side effects entirely but requires repeated office visits, involves multiple needle sticks per session, and can be expensive without insurance coverage.
If anxiety or stress is a major trigger for your sweating, it’s worth mentioning this to your doctor. While the medications above address the sweating itself regardless of cause, treating the underlying anxiety can sometimes reduce the severity enough to make topical treatments more effective on their own.
