How to Help Your Patients Find Drysol In Stock: A Provider's Guide

Your patient was diagnosed with hyperhidrosis, you wrote them a Drysol prescription — and now they're calling your office because three pharmacies in a row told them it's out of stock. This is an increasingly common scenario, and it puts both patients and practice staff in a frustrating position. Here's a systematic guide to help you help your patients find Drysol efficiently.

Understanding Why Patients Can't Find Drysol

Drysol is not on the FDA or ASHP national shortage list, but it's a specialty topical that many pharmacies stock infrequently. It contains flammable anhydrous ethanol, which complicates handling and storage. Demand has increased as hyperhidrosis diagnosis has expanded through telehealth — but pharmacy stocking hasn't kept pace. The result: a product that is available nationally but may not be on the shelf at any given local pharmacy.

Strategy 1: Write a Generic Prescription

The single most impactful thing you can do at the prescribing stage: write the generic name instead of the brand. Prescribing "aluminum chloride hexahydrate 20% topical solution" — rather than "Drysol" — allows the pharmacist to dispense any available equivalent, including Hypercare or compounded versions. This alone significantly increases the probability that a prescription gets filled on the first attempt.

Strategy 2: Counsel Patients at the Point of Prescribing

Set expectations before patients leave your office or telehealth visit. Let them know that Drysol may not be at their usual pharmacy and give them a clear plan:

Try an independent or compounding pharmacy if the chain pharmacy is out

Check Amazon Pharmacy or Costco Pharmacy via mail-order

Use OTC Certain Dri (12%) as a bridge while searching

Try medfinder — they call pharmacies to check stock on the patient's behalf

Strategy 3: Establish a Relationship With a Local Compounding Pharmacy

If your practice sees significant hyperhidrosis volume, consider building a referral relationship with a local compounding pharmacy. Compounding pharmacies can prepare aluminum chloride hexahydrate at any required concentration (typically 10–20%) in alcohol-based or gel-based vehicles. This is especially valuable for patients with axillary irritation from the standard 20% alcohol solution — a 15% aluminum chloride in salicylic acid gel may provide equivalent efficacy with reduced irritation.

Strategy 4: Know the Insurance Step Therapy Requirements Before Escalating

Many insurers (Cigna, Anthem, UnitedHealthcare, Aetna) require prior documentation of aluminum chloride failure before approving Qbrexza (glycopyrronium cloth 2.4%) or Sofdra (sofpironium gel). If your patient has indeed failed Drysol — whether due to intolerance or inadequate response — document it clearly now. Note the concentration used, duration of trial, and the specific reason for failure. This documentation will be required when submitting prior authorization.

Strategy 5: For Patients Who Need It Now — Provide a Bridge Plan

For patients in acute distress who can't wait for their prescription to be filled, a few options can provide same-day relief:

OTC Certain Dri (12% aluminum chloride): Available at CVS, Walgreens, and most major drugstores. No prescription needed.

Duradry: A consumer OTC antiperspirant system with aluminum zirconium trichlorohydrex; not as strong as 20% aluminum chloride but widely available online without a prescription.

How to Reduce Pharmacy Call-Backs to Your Office

Pharmacy call-backs consume significant staff time and delay care. You can reduce them by:

Writing generic prescriptions that allow substitution

Including a DAW-0 (dispense as written) field that's blank or set to allow substitution

Providing patients with a written backup plan at checkout or discharge

Directing patients to medfinder.com to search for stock before calling your office

medfinder for Providers

medfinder is a service that contacts pharmacies on behalf of patients to check whether a specific medication is available. For providers who see frequent hyperhidrosis cases, sharing medfinder with patients at the point of care reduces the burden of pharmacy hunting on both staff and patients.
