Helping Patients Navigate Benzoyl Peroxide/Erythromycin Access Challenges

As a prescriber, you've likely encountered patients who call back frustrated because their pharmacy couldn't fill a Benzoyl Peroxide/Erythromycin (Benzamycin) prescription. These callbacks consume staff time, delay treatment, and erode patient confidence. While Benzoyl Peroxide/Erythromycin is not in formal shortage, it is genuinely harder to find than most topical acne medications.

This guide provides actionable steps your practice can take to reduce fill failures, support patients proactively, and decide when an alternative is the better path forward.

Current Availability of Benzoyl Peroxide/Erythromycin

Benzoyl Peroxide/Erythromycin (Erythromycin 3%/Benzoyl Peroxide 5% topical gel) is manufactured by Bausch Health (brand Benzamycin) and Rising Pharmaceuticals (generic). Both products remain FDA-approved and in production.

However, real-world stocking has declined significantly over the past several years:

• Chain pharmacies (CVS, Walgreens, Rite Aid) frequently do not carry it as a standing inventory item
• Refrigeration requirements for Benzamycin Gel further limit pharmacy willingness to stock
• Distributor availability can be inconsistent, with some regional distributors reporting limited supply
• Independent pharmacies are more likely to carry or order the product, especially those serving dermatology practices

The net effect is that patients often visit two or three pharmacies before finding the medication — or give up and call your office asking for an alternative.

Why Patients Can't Find Benzoyl Peroxide/Erythromycin

Understanding the root causes helps inform your approach:

1. Market shift: Clindamycin/Benzoyl Peroxide and Adapalene/Benzoyl Peroxide have become the dominant topical combination products, reducing demand for Erythromycin-based formulations
2. Few manufacturers: Only two companies produce the product, creating supply vulnerability
3. Cold chain logistics: The 2–8°C storage requirement and 3-month post-dispensing expiration discourage pharmacy stocking
4. Low-volume product: Pharmacies prioritize shelf space for high-turnover items, and Benzoyl Peroxide/Erythromycin no longer qualifies in most markets

What Providers Can Do: 5 Practical Steps

Step 1: Check Availability Before Prescribing

The single most effective way to reduce fill failures is to check pharmacy stock before sending the prescription. Medfinder for Providers offers real-time availability data for Benzoyl Peroxide/Erythromycin and other hard-to-find medications.

Have your medical assistant or prescribing nurse check Medfinder during the patient visit. If a nearby pharmacy has the medication in stock, send the e-prescription directly there. This one step can eliminate most callbacks.

Step 2: Prescribe Generically With Substitution Allowed

Write prescriptions for "Erythromycin/Benzoyl Peroxide 3%/5% topical gel" rather than brand Benzamycin. Allowing substitution gives the pharmacy flexibility to dispense whichever manufacturer's product they can source. This significantly improves fill rates.

Also specify the 46.6g jar size when appropriate — it's the standard quantity and offers better value for the patient.

Step 3: Build Relationships With Local Pharmacies

Identify one or two pharmacies in your area that reliably stock or can quickly order Benzoyl Peroxide/Erythromycin. Options to explore:

• Independent pharmacies near your practice that serve dermatology patients
• Compounding pharmacies that can prepare custom Erythromycin/Benzoyl Peroxide formulations
• Specialty pharmacies affiliated with dermatology groups

Once you've identified reliable sources, maintain a list that your front desk or nursing staff can share with patients at the point of prescribing.

Step 4: Proactively Counsel Patients

When prescribing Benzoyl Peroxide/Erythromycin, set expectations with patients:

• Explain that the medication may not be available at every pharmacy
• Recommend they call ahead or check Medfinder before making a trip
• Let them know the gel needs to be refrigerated and discarded after 3 months
• Provide a list of pharmacies you know stock it, or suggest trying an independent pharmacy

This proactive approach reduces frustration and prevents patients from assuming the medication is discontinued or unavailable.

Step 5: Have an Alternative Ready

For some patients, the most practical path is to switch to a more accessible medication. Have your preferred alternatives documented so you or your team can offer a quick switch when needed:

• Clindamycin/Benzoyl Peroxide: Closest substitute; widely available generics at $15–$50
• Adapalene/Benzoyl Peroxide (Epiduo): Strong evidence; once-daily dosing; generic available
• Clindamycin Phosphate topical + OTC Benzoyl Peroxide wash: Two-product approach that achieves similar combination therapy

Alternatives at a Glance

Here's a quick reference table for the most common alternatives:

• Clindamycin/Benzoyl Peroxide (BenzaClin, Duac, Onexton): Topical antibiotic + antiseptic; 1–2x daily; generic $15–$50; widely available at all pharmacies
• Adapalene/Benzoyl Peroxide (Epiduo): Retinoid + antiseptic; once daily; generic $30–$70; strong evidence for inflammatory and comedonal acne
• Adapalene (Differin): Retinoid only; once daily; OTC $12–$15; best for mild acne or maintenance
• Clindamycin Phosphate (Cleocin T): Antibiotic only; 2x daily; generic $10–$25; pair with Benzoyl Peroxide wash to reduce resistance

Workflow Tips for Your Practice

Integrating availability checks into your prescribing workflow doesn't have to be complicated. Here are practical tips:

• Bookmark medfinder.com/providers on workstations in exam rooms and the nursing station
• Create a "hard-to-find medications" reference list with preferred pharmacy contacts for Benzoyl Peroxide/Erythromycin and other products with availability challenges
• Add a note to your EMR template: When prescribing Benzoyl Peroxide/Erythromycin, include a staff reminder to check Medfinder and confirm pharmacy stock
• Train front desk staff to direct patient callbacks about unfilled prescriptions to Medfinder before scheduling a provider callback
• Document preferred alternatives in your EMR: Create quick-switch order sets for Clindamycin/Benzoyl Peroxide and Adapalene/Benzoyl Peroxide

Final Thoughts

Benzoyl Peroxide/Erythromycin remains a clinically appropriate treatment for certain acne patients, but access barriers are real and unlikely to improve significantly in the near term. By checking availability proactively, prescribing generically, building pharmacy relationships, and having alternatives ready, your practice can minimize fill failures and keep patients on effective treatment.
