How to Help Your Patients Find Dorzolamide in Stock: A Provider's Guide

One of the more frustrating realities of managing glaucoma patients in 2026 is pharmacy availability. Even when dorzolamide is not in a formal nationwide shortage, individual pharmacies go out of stock — and patients who depend on consistent intraocular pressure control cannot afford treatment gaps. This guide gives you practical tools and talking points to help your patients get their medication faster.

Why Pharmacy Availability Gaps Happen for Dorzolamide

The brand-name Trusopt has been discontinued, leaving the market entirely to generic manufacturers. While this normally increases supply resilience, it can also create confusion at the pharmacy level — systems may not flag the drug correctly, or pharmacies may be contracted with distributors that carry only certain manufacturers' generics. Small pharmacies in particular may stock only a handful of bottles at a time.

For patients managing open-angle glaucoma or ocular hypertension, a 2-3 day gap without dorzolamide means rising IOP — and for patients near the edge of their target pressure, that matters clinically.

Step 1: Counsel Patients to Refill Early — Before They're Out

The most effective intervention is proactive: instruct patients at every visit to refill their dorzolamide when they have about 10-14 days of medication remaining — not when the bottle is empty. This simple change gives them time to locate the drug if their usual pharmacy is out.

Consider adding a standard check-in question to your visit workflow: "Were you able to refill all of your eye medications without any problems since your last visit?" This often surfaces access issues patients haven't mentioned.

Step 2: Write Prescriptions That Give Patients Flexibility

When writing prescriptions for dorzolamide, consider these practices that improve patient access:

• Write for the generic name ("dorzolamide HCl ophthalmic solution 2%"), not "Trusopt." Trusopt is discontinued; writing the brand may cause confusion at some pharmacies.
• Prescribe 90-day supplies when clinically appropriate. Mail-order pharmacies carry larger inventory and rarely run out of generic ophthalmic medications. Encourage patients on stable regimens to fill 90 days via mail.
• Authorize DAW-0 (generic substitution permitted). This gives pharmacies the flexibility to dispense any FDA-approved generic, regardless of manufacturer, which improves the odds of finding stock.

Step 3: Recommend medfinder to Patients Having Trouble Finding the Drug

When patients report they can't find dorzolamide, direct them to medfinder. It's a paid service that contacts local pharmacies to check which ones have a specific medication in stock. The patient enters their medication, dosage, and location — medfinder does the calling and texts back which pharmacies currently have it. This can save your staff time and helps patients find their medication quickly without calling around.

Step 4: Keep Office Samples for Bridge Use

If your practice has access to manufacturer or distributor samples, maintaining a small stock of dorzolamide or brinzolamide samples can provide a 1-2 week bridge for patients who call in with urgent stock-out issues. This is especially valuable for elderly patients or those with transportation barriers who cannot easily visit multiple pharmacies.

Step 5: Have a Clear Therapeutic Substitute Protocol

Create a clear policy in your practice for handling dorzolamide availability calls. For example:

1. Patient calls with stock-out issue → have them use medfinder or call 3 major chain pharmacies first
2. If unavailable within 48 hours → prescriber switches to brinzolamide 1% TID or dorzolamide/timolol BID (if no contraindications)
3. Document the medication change in the chart and schedule an IOP check at 4-6 weeks
4. Instruct patient to call immediately if they experience vision changes or eye discomfort

Step 6: Consider High-Risk Patients for Priority Follow-Up

Certain patients require special attention when medication access is uncertain:

• Patients with advanced glaucoma (cup-to-disc ratio >0.7, near-split fixation)
• Patients on a single-agent regimen where dorzolamide is their only IOP-lowering therapy
• Patients with poor adherence history — a stock-out often becomes an extended interruption
• Elderly or medically complex patients with limited transportation or cognitive barriers to navigating multiple pharmacies

Formulary and Insurance Navigation Tips

Generic dorzolamide is typically covered at Tier 1 or Tier 2 on most commercial formularies and Medicare Part D plans. Prior authorization is rarely required for the generic. However, plan-specific manufacturer restrictions can affect which pharmacies can dispense at the lowest copay. If a patient is hitting unexpected cost or access barriers, consider:

• Suggesting GoodRx as a bypass — coupon prices ($15-$20) sometimes beat insurance copays
• Directing patients to mail-order, which often has preferred formulary positioning and lower costs
• Checking NeedyMeds or Partnership for Prescription Assistance for uninsured or underinsured patients
