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

You prescribe Bactroban (mupirocin) for a patient's impetigo, infected wound, or MRSA decolonization. A few hours later, your front desk gets a call: "The pharmacy says they're out. What do we do now?" This scenario plays out regularly at practices across the country, particularly during summer and fall when impetigo peaks.

This guide gives you a practical protocol to handle Bactroban stock issues efficiently — minimizing callbacks and getting your patients treated as quickly as possible.

Step 1: Write for Generic Mupirocin from the Start

The simplest way to avoid stock issues is to prescribe by generic name — "mupirocin 2% ointment" or "mupirocin 2% cream" — rather than "Bactroban." Generic mupirocin is:

Therapeutically equivalent to brand Bactroban (FDA-rated AB)

Produced by multiple manufacturers, increasing supply redundancy

Stocked by more pharmacies at lower cost to patients

Covered as Tier 1 or Tier 2 on virtually all formularies — no prior auth needed

Step 2: Specify the Correct Formulation

Mupirocin comes in three formulations, and availability varies across them:

Mupirocin 2% ointment (22g tube): FDA-approved for impetigo; most widely stocked; apply 3 times daily for up to 10 days

Mupirocin 2% cream (15g or 30g tube): FDA-approved for secondarily infected traumatic lesions; good alternative to ointment for some patients who prefer a lighter texture

Mupirocin calcium 2% nasal ointment: For MRSA nasal decolonization; less commonly stocked at retail pharmacies — may need to be ordered through a specialty or hospital pharmacy

Step 3: Build a Pharmacy Stock Callback Protocol

Train your front desk or medical assistants on a standard response for patients calling about medication unavailability:

First, verify: "Did they say the brand or the generic is out? Have you tried asking for generic mupirocin?"

Direct to medfinder: "You can use medfinder.com to find which pharmacies near you have it in stock. They'll call on your behalf and text you the results."

If still unavailable: escalate to the prescriber to authorize a switch to retapamulin or oral cephalexin based on clinical situation

Step 4: Know Your Ready-to-Prescribe Alternatives

Having alternative prescriptions pre-authorized or templated in your EHR saves significant time. Consider building order sets for:

Retapamulin (Altabax) 1% ointment: Apply twice daily for 5 days to affected area; for MSSA/streptococcal impetigo; approved ages 9 months and older

Cephalexin 250–500 mg oral: Twice to four times daily for 7–10 days; for extensive or widespread impetigo or when topical therapy is impractical

Trimethoprim/sulfamethoxazole (TMP-SMX): If CA-MRSA is suspected and clindamycin resistance is present in your community

Step 5: Use medfinder to Reduce Callbacks

medfinder is designed to solve the "my pharmacy is out of stock" problem without involving your clinical staff. When you encounter medication access issues in your practice, recommend medfinder for providers as your first-line resource for patients. medfinder calls pharmacies near the patient, confirms stock, and texts the results. The patient goes directly to the right pharmacy — no extra work for your staff.

Special Situations: MRSA Nasal Decolonization

For patients undergoing pre-surgical MRSA decolonization with mupirocin nasal ointment, the timeline is often tighter — decolonization is typically scheduled 5 days before the procedure. If the nasal ointment is unavailable at retail pharmacies in your area, consider routing the prescription through a hospital outpatient pharmacy, a compounding pharmacy, or a specialty pharmacy that reliably stocks this formulation.
