A provider-focused briefing on Debacterol availability in 2026. Covers supply status, prescribing implications, alternatives, and patient access strategies.
Debacterol (sulfonated phenolics/sulfuric acid) is a topical chemical cautery agent used for the treatment of recurrent aphthous stomatitis (canker sores) and oral mucosal ulcerations. While not FDA-approved as a drug — it's classified as an OTC medical device — Debacterol has been a valued tool in dental and primary care practices for its ability to provide immediate pain relief and accelerate ulcer healing with a single application.
In 2026, providers continue to face challenges sourcing Debacterol for their practices and patients. This briefing covers the current availability picture, clinical implications, alternative treatment strategies, and tools to help patients access the product.

There is currently no indication that Debacterol's availability situation will significantly improve in the near term. Epien Medical has not announced plans to expand manufacturing or distribution. No competing chemical cautery products for OTC canker sore treatment have entered the U.S. market.
Providers should:
Debacterol occupies a unique space in oral medicine — highly effective, well-regarded by patients and providers, but persistently difficult to source. Its OTC medical device classification means it falls outside the standard pharmaceutical shortage monitoring and distribution systems that providers rely on for other medications.
