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

If you practice ophthalmology, optometry, or primary care, you've likely fielded frustrated calls from patients who were prescribed Maxitrol (neomycin/polymyxin B/dexamethasone ophthalmic) only to find it unavailable at their local pharmacy. While no national shortage of Maxitrol is currently declared, localized stock issues do occur — and having a clear workflow to handle these calls efficiently benefits both your patients and your practice.

Why Patients Call Back About Maxitrol Availability

Maxitrol is an older, well-established medication that many providers have prescribed reflexively for decades. Its long track record and low cost (generic versions can be under $20 with coupons) make it a first-line choice for many inflammatory eye conditions. But because it's a specialty ophthalmic medication, pharmacies typically carry smaller quantities — and a run on stock at a few local pharmacies can temporarily make it seem unavailable across an area.

The most common reason patients call back: they went to their usual pharmacy, were told Maxitrol is out of stock, and don't know where else to look. With a streamlined workflow, your staff can resolve most of these calls quickly.

Step 1: Proactively Authorize Generic Substitution

When prescribing Maxitrol, the simplest way to reduce future callbacks is to proactively authorize generic substitution on the prescription. Generic neomycin/polymyxin B/dexamethasone ophthalmic drops and ointment are therapeutically equivalent to brand-name Maxitrol, significantly cheaper, and — because multiple manufacturers produce the generic — often more readily available at local pharmacies.

Avoid "brand medically necessary" designations unless there is a specific clinical reason, as this prevents pharmacists from offering the generic to patients whose insurance may also cover it at a lower copay.

Step 2: Direct Patients to medfinder

One of the most efficient tools you can recommend is medfinder.com. medfinder calls pharmacies near the patient's location to identify which ones have the medication in stock, then texts the patient the results. This saves patients from spending hours on hold calling pharmacies one by one — and it reduces the volume of callbacks your staff has to manage.

Consider adding medfinder as a patient handout resource in your office — particularly for medications like Maxitrol where local stock can be inconsistent.

Step 3: Have a Ready Alternative Prescription Prepared

For patients who have called back about unavailability and need an alternative quickly, having a pre-prepared alternative prescription can save time. The most clinically appropriate first alternative is:

TobraDex (tobramycin/dexamethasone ophthalmic): Drops or ointment. Same dexamethasone steroid component; tobramycin substitutes for neomycin + polymyxin B. Generic available. Appropriate for most patients who can take Maxitrol.

Zylet (tobramycin/loteprednol ophthalmic): Preferable if patient has documented IOP response to dexamethasone or has glaucoma history. Brand only; cost may be a barrier for some patients.

Blephamide (sulfacetamide/prednisolone): For sulfa-tolerant patients; appropriate where anti-infective coverage is needed alongside a steroid. Generic available.

Step 4: Leverage Compounding for Refractory Cases

In cases where commercial stock truly cannot be located and commercial alternatives are contraindicated (e.g., neomycin allergy AND sulfa allergy), consider directing patients to a compounding pharmacy. A compounding pharmacist can prepare a custom formulation of neomycin/polymyxin B/dexamethasone — or, more practically, a custom tobramycin/dexamethasone formulation — from bulk pharmaceutical ingredients. Remind patients that compounded preparations are not FDA-approved and may not be covered by insurance.

Setting Up a Front-Desk Protocol for Maxitrol Callbacks

Consider creating a short standing protocol for front-desk and medical assistant staff:

Patient calls saying Maxitrol is out of stock at their pharmacy.

Staff confirms whether generic was authorized and, if so, advises patient to ask specifically for the generic (neomycin/polymyxin B/dexamethasone ophthalmic) at other pharmacies.

Staff directs patient to medfinder.com to locate nearby pharmacies with stock.

If medication cannot be located, staff escalates to provider for consideration of TobraDex or other alternative prescription.

This simple protocol reduces provider interruptions while ensuring patients get timely access to treatment.

Key Clinical Reminders for Post-Surgical Protocols

Maxitrol is commonly used in cataract surgery post-operative regimens for the first week, often in combination with other drops. If your standard post-op kit includes Maxitrol and patients are having difficulty filling it, consider pre-establishing a TobraDex or equivalent alternative as a standing backup in your post-op prescription set.
