Sirolimus (Rapamune) and dental care
Sirolimus is one of the most common medication causes of recurrent aphthous-like mouth ulcers. Many transplant patients on sirolimus develop persistent mouth sores that significantly affect eating and quality of life. The ulcers respond to dose adjustment and topical care but rarely resolve fully while on the medication. Coordination with the transplant team is part of management.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
