Struggling to find Benzoyl Peroxide/Erythromycin (Benzamycin) at your pharmacy? Learn why this acne medication is hard to find in 2026 and what you can do.
You went to pick up your prescription for Benzoyl Peroxide/Erythromycin — also known by the brand name Benzamycin — and the pharmacist told you it's out of stock. Maybe they said they can't order it, or they're not sure when it will be back. If this sounds familiar, you're not imagining things. Many patients across the country are running into the same problem.
Benzoyl Peroxide/Erythromycin is a topical gel used to treat mild to moderate acne. It combines two active ingredients — Erythromycin (a macrolide antibiotic) and Benzoyl Peroxide (an antiseptic that kills acne-causing bacteria). Together, they work better than either ingredient alone. But despite being an effective treatment, finding this medication can be surprisingly difficult.
In this post, we'll explain what Benzoyl Peroxide/Erythromycin is, why it's hard to find in 2026, and what steps you can take to get your prescription filled.
Benzoyl Peroxide/Erythromycin is a prescription topical gel used to treat acne vulgaris. The brand name is Benzamycin, originally made by Bausch Health (formerly Valeant International). A generic version is also available from Rising Pharmaceuticals.
The gel contains 3% Erythromycin and 5% Benzoyl Peroxide. You apply a thin layer to affected skin twice a day — once in the morning and once in the evening. Erythromycin stops bacteria from growing by blocking their ability to make proteins, while Benzoyl Peroxide releases oxygen to kill acne-causing bacteria and helps peel away dead skin cells.
It comes in two sizes: a 23.3g jar and a 46.6g jar. One important thing to know — Benzamycin Gel needs to be refrigerated and should be thrown away after 3 months, even if there's medication left.
There are several reasons why you might be struggling to locate this medication at your local pharmacy.
Unlike widely prescribed acne medications, Benzoyl Peroxide/Erythromycin has very few manufacturers. The brand-name Benzamycin is made by Bausch Health, and the generic is produced by Rising Pharmaceuticals. With only a small number of companies making this product, any disruption in production or distribution can make the drug harder to find.
Because Benzoyl Peroxide/Erythromycin is less commonly prescribed than alternatives like Clindamycin/Benzoyl Peroxide (BenzaClin), many pharmacies don't keep it on their shelves. Large chain pharmacies tend to stock only the most popular acne treatments, which means this combination can be a special-order item. That adds days — sometimes weeks — to the process of filling your prescription.
Benzamycin Gel needs to be stored in the refrigerator. This creates a logistical challenge for pharmacies, which have limited cold-storage space. Some pharmacies may avoid stocking it altogether because of this requirement, especially if demand in their area is low.
Over the past several years, dermatologists and primary care providers have increasingly favored newer combination products like Adapalene/Benzoyl Peroxide (Epiduo) and Clindamycin/Benzoyl Peroxide (Duac, Onexton). As prescriptions for Benzoyl Peroxide/Erythromycin have declined, distributors and pharmacies have reduced their inventory of this product. The result is a self-reinforcing cycle: lower demand leads to lower supply, which makes it even harder for the patients who do need it.
If you're having trouble finding Benzoyl Peroxide/Erythromycin, here are some practical steps you can take.
Medfinder helps you search for pharmacies that have your medication in stock — right now. Instead of calling pharmacy after pharmacy, you can check availability online and find the closest location with Benzoyl Peroxide/Erythromycin on their shelves. It's free to use and can save you hours of frustration.
Independent and compounding pharmacies often have more flexibility in what they stock. They may be more willing to order Benzoyl Peroxide/Erythromycin for you or even compound a similar formulation. Ask your pharmacist if this is an option.
If you simply can't find Benzoyl Peroxide/Erythromycin, talk to your prescriber about switching to a similar medication. Clindamycin/Benzoyl Peroxide works in a similar way and is much more widely available. Adapalene/Benzoyl Peroxide (Epiduo) is another option that targets acne through a different mechanism.
If the brand-name Benzamycin is unavailable, ask your pharmacist to fill the generic Erythromycin/Benzoyl Peroxide gel instead. The generic version from Rising Pharmaceuticals is therapeutically equivalent and typically costs much less — around $31 to $45 with a discount card compared to $140 or more for the brand.
Cost can also be a factor in availability. Here's a quick breakdown:
