Recurrent Aphthous Stomatitis When Topical Agents Have Not Controlled Ulcers
Clinical scenario
This protocol addresses patients with recurrent aphthous stomatitis (RAS) who experience multiple ulcer episodes each month, or who present with severe oral pain and difficulty in eating — and whose condition has not been adequately managed with topical therapy alone.
Previous treatment — goals not achieved
First-line management with topical agents was the initial approach. Options in that line included:
- Topical anesthetic (viscous lidocaine)
- Antibiotic mouthwash (tetracycline)
- Antiseptic mouthwash (chlorhexidine gluconate)
- Topical glucocorticoids (fluocinonide or clobetasol)
- Oral adhesive (amlexanox)
The goals — decreasing symptoms, reducing ulcer number and size, and increasing disease-free periods — were not sufficiently met, indicating a need for escalation.
Next-line approach (partial overview)
When topical management is insufficient, oral systemic therapy — involving immunomodulatory and anti-inflammatory agents — becomes the indicated approach for severe, constantly recurring ulcerations.
The complete structured regimen, including agent selection and sequencing, is available via the link below.
Treatment goals
Decrease in symptoms; reduction in ulcer number and size; increase in disease-free periods.
