Summary
Extreme overdosage of chlorhexidine gluconate mouthwash caused significant oral mucosal changes, resembling leukoplakia. Reducing the dosage resolved these adverse effects, highlighting the importance of proper use.
Area of Science:
- Oral Medicine
- Dermatology
- Pharmacology
Background:
- Chlorhexidine gluconate is a widely used antiseptic agent in oral rinses.
- Adverse effects are typically mild, but overdosage can lead to unusual presentations.
Observation:
- A patient presented with severe oral mucosal changes after excessive use of chlorhexidine gluconate mouthwash.
- The observed changes included significant mucosal thickening, clinically mimicking leukoplakia.
Findings:
- The mucosal alterations were distinct from previously documented lesions associated with chlorhexidine.
- Complete resolution of the leukoplakia-like changes occurred upon dose reduction.
Implications:
- This case highlights a rare but distinct side effect of chlorhexidine gluconate overdosage.
- Clinicians should be aware of potential severe mucosal reactions and emphasize correct dosage instructions to patients.
