Drysol Availability: What Providers and Prescribers Need to Know in 2026

As the first-line prescription treatment for primary focal hyperhidrosis, Drysol (aluminum chloride hexahydrate 20% topical solution) is a medication many of your patients rely on. But a growing number of patients are reporting difficulty filling this prescription at their local pharmacies — and that's landing back in your office. Here's what you need to know as a provider in 2026.

Current Supply Status

As of mid-2026, there is no declared national shortage of aluminum chloride hexahydrate 20% (Drysol) by the FDA or ASHP. The product continues to be manufactured by Person & Covey and distributed through standard pharmaceutical channels. However, localized stock-outs are common and occur for structural reasons: Drysol is a low-volume specialty topical with flammable classification, and many pharmacies do not prioritize carrying it in stock.

Clinical Context: Why This Drug Matters

Aluminum chloride hexahydrate is recommended as first-line therapy for mild-to-moderate primary focal hyperhidrosis by the American Academy of Dermatology and other major clinical guidelines. It works by forming an aluminum-polysaccharide plug in the sweat duct, physically blocking eccrine secretion. Reduction in sweating typically occurs within 48 hours of first application for axillary hyperhidrosis.

The cost advantage over second-line agents is substantial: Drysol costs $15–$37 per bottle with coupons, compared to $580–$840 per month for Qbrexza (glycopyrronium) and $1,000–$1,500 per Botox session. For the majority of patients with mild-to-moderate disease, aluminum chloride is both effective and highly cost-effective.

What Your Patients Are Experiencing

Patients prescribed Drysol often encounter one of three scenarios at the pharmacy:

The pharmacy has Drysol in stock — no problem.

The pharmacy can order it — 3-5 day wait.

The pharmacy tells the patient it's unavailable with no clear ETA — patient returns to you frustrated.

Scenario 3 is increasingly common. It's worth proactively counseling patients at the time of prescribing about what to do if they can't immediately fill the script.

Prescribing Recommendations and Equivalents

If your patient cannot locate Drysol, consider the following prescribing alternatives:

Hypercare (aluminum chloride hexahydrate 20%): Same active ingredient and concentration as Drysol. Direct therapeutic equivalent. Write the generic name on the prescription ("aluminum chloride hexahydrate 20% topical solution") to allow pharmacist substitution.

Xerac AC (aluminum chloride hexahydrate 6.25%): Lower concentration; appropriate for patients with skin sensitivity or as initial therapy. May be less effective for severe cases.

Compounded aluminum chloride hexahydrate: A compounding pharmacy can prepare aluminum chloride hexahydrate in any concentration (typically 10–20%) in an appropriate vehicle. Some patients tolerate compounded gel formulations better than the alcohol-based solution.

Bridge with OTC Certain Dri (12%): For patients waiting to fill Drysol, recommend OTC Certain Dri. It contains 12% aluminum chloride and requires no prescription.

Step Therapy and Second-Line Options

If a patient has failed aluminum chloride (inadequate efficacy after 4 weeks of correct use, or significant intolerance), document this clearly. This documentation is required by most commercial plans — including Cigna, Anthem, and UnitedHealthcare — before they will approve Qbrexza (glycopyrronium 2.4% cloth) or Sofdra (sofpironium 12.45% gel). Without prior documentation of aluminum chloride failure, prior authorization for these agents will likely be denied.

Patient Counseling Points at Prescribing

Apply to completely dry skin at bedtime; let the alcohol evaporate before covering with clothing or a tee-shirt

Do not apply to recently shaved, broken, or irritated skin

Leave on 6–8 hours, wash off in the morning

Apply nightly for the first week, then reduce to 1–2x weekly for maintenance

Irritation is common initially — advise temporary discontinuation if severe, then restart at lower frequency

Not recommended in pregnancy — no assigned pregnancy category by manufacturer
