Background: Recurrent aphthous stomatitis (RAS) is a common disorder characterized by episodic ulcerations in the oral mucosa. Although colchicine has been a common systemic treatment for RAS, there is still considerable uncertainty regarding its efficacy and drug survival in this setting.

Objective: We aimed to study drug survival, efficacy, and safety of colchicine for the treatment of RAS, especially in the real clinical setting.

Methods: Between 2012 and 2016, 150 patients given colchicine for RAS were selected for a single-centre retrospective study of real-world efficacy and drug survival.

Results: Among the 114 patients who qualified, 81.6% showed moderate or substantial responses (>25% improvement). Gastrointestinal complications (16.7%), neutropenia (3.5%), and liver enzyme elevation (4.4%) were reported within 2 weeks after initiating treatment. Delayed adverse manifestations were rare. One year after onset, colchicine use was sustained in roughly one-half (49.5%) of patients, whereas many (30.3%) had discontinued the drug, primarily due to lack of efficacy or adverse events. In Cox proportional hazard analysis, minor ulcers were identified as potential determinants of longer drug survival owing to less probability of non-efficacy. However, major ulcers had emerged as predictors of early discontinuation due to lack of efficacy.

Conclusion: In patients with RAS, colchicine may be an effective and safe treatment amenable to long-term maintenance. Monitoring of adverse events within 2 weeks after initiating treatment is advisable to ensure safe administration.
