Your Patients Can't Find Aluminum Chloride — Here's How You Can Help

You prescribe Aluminum Chloride Hexahydrate for a patient with hyperhidrosis. Two days later, they call back: their pharmacy doesn't have it, and neither does the one down the street. This scenario has become increasingly common, and it's a problem that affects patient outcomes, trust, and compliance.

As a provider, you have more leverage than your patients do when it comes to navigating medication availability. This guide gives you five concrete steps to help your patients find Aluminum Chloride in stock, plus a framework for when it makes sense to switch to an alternative.

Current Availability of Aluminum Chloride

As of early 2026, Aluminum Chloride Hexahydrate is not on the FDA or ASHP drug shortage lists. Person & Covey continues to manufacture Drysol, and generic versions remain in production. The issue is not a true shortage but rather a distribution and stocking problem:

• Chain pharmacy algorithms may deprioritize low-volume products
• Generic manufacturer output fluctuates based on demand signals
• The medication's classification as potentially cosmetic reduces insurance-driven demand
• Patients give up searching and don't report the gap, masking the true scope of the problem

Why Patients Can't Find Aluminum Chloride

Understanding the patient experience is key to helping effectively. Here's what your patients typically encounter:

1. Their usual pharmacy is out of stock and offers no timeline for restock
2. They call 3-5 other pharmacies and get the same answer or long hold times
3. They don't know about compounding pharmacies as an option
4. They feel embarrassed asking about an "antiperspirant" and may minimize the medical necessity
5. They give up and either go untreated or try OTC products that don't work well enough

By intervening proactively at the prescribing stage, you can short-circuit this frustrating cycle.

5 Steps Providers Can Take

Step 1: Check Availability Before the Patient Leaves

Use Medfinder for Providers to check which pharmacies near your patient's home or office have Aluminum Chloride in stock. This takes under a minute and dramatically improves the chance of a successful fill on the first try.

Send the prescription directly to a pharmacy you've confirmed has the medication in stock.

Step 2: Prescribe Generically

Write the prescription as "Aluminum Chloride Hexahydrate 20% topical solution" rather than specifying Drysol. This gives the pharmacy flexibility to dispense any available manufacturer's product. Ensure DAW (Dispense As Written) is set to 0 to allow substitution.

Step 3: Establish Compounding Pharmacy Relationships

Identify 1-2 compounding pharmacies in your area that can prepare Aluminum Chloride solutions. Because the formulation is straightforward — aluminum chloride hexahydrate dissolved in anhydrous ethanol — most compounding pharmacies can prepare it quickly and affordably ($15 to $40).

Keep these pharmacy names and fax numbers in your EHR system or prescribing workflow so you can redirect prescriptions quickly when retail pharmacies are out of stock.

Step 4: Provide Written Guidance to Patients

Give patients a handout or direct them to resources that explain:

• How to use Medfinder to check pharmacy stock
• That independent pharmacies may have better availability
• That compounding is an option (with your practice's recommended compounding pharmacy)
• That OTC Certain Dri (12%) can serve as a temporary bridge

Step 5: Document Medical Necessity

For patients whose insurance denies coverage of Aluminum Chloride as "cosmetic," providing a letter of medical necessity that documents the diagnosis of hyperhidrosis (ICD-10: R61) and functional impairment can help with appeals. While the cash price is low ($10-$35), some patients are on fixed incomes or have high medication burdens where every dollar matters.

When to Consider Alternatives

If Aluminum Chloride is genuinely unavailable or if the patient has had an inadequate response, consider these evidence-based alternatives:

• Glycopyrronium Tosylate wipes (Qbrexza): FDA-approved for axillary hyperhidrosis, ages 9+. Convenient once-daily application. Cost: ~$580/month without insurance; commercial coverage improving. Best for patients with isolated underarm sweating.
• OnabotulinumtoxinA (Botox): FDA-approved for severe axillary hyperhidrosis refractory to topical agents. 50 units per axilla, retreatment every 6-12 months. Cost: $1,000-$1,500/session. Many insurance plans cover it with prior authorization when documented as treatment-refractory.
• Oral Glycopyrrolate: Off-label for generalized hyperhidrosis. 1-2 mg BID-TID. Cost: $10-$30/month generic. Good option for patients with sweating beyond the axillae. Monitor for anticholinergic side effects (dry mouth, constipation, urinary retention, blurred vision).
• miraDry: FDA-cleared microwave thermolysis for permanent reduction of axillary sweat glands. One-time investment of $2,000-$3,000. Consider for patients seeking a long-term solution.

Workflow Tips for Your Practice

Integrating these strategies into your daily workflow doesn't have to be time-consuming:

• Bookmark medfinder.com/providers on clinic computers for quick stock checks
• Add compounding pharmacy contacts to your EHR favorites or prescribing directory
• Create a hyperhidrosis visit template that includes availability discussion points
• Train front desk staff to direct patients to Medfinder when they call about unfilled prescriptions
• Keep a list of current cash prices to set patient expectations: $10-$13 with coupon for generic, $22-$35 for brand Drysol

Final Thoughts

Aluminum Chloride is effective, affordable, and well-tolerated — which makes it all the more frustrating when patients can't find it. By checking availability proactively, prescribing generically, maintaining compounding pharmacy relationships, and equipping patients with the right tools, you can significantly reduce the access gap.

Your patients depend on you not just for the prescription, but for the guidance to fill it. A few extra minutes at the prescribing stage can save them hours of frustration and keep them on the treatment that works.
