Clinical Pharmacist's Role in Preventing and Managing Drug-Induced Oral Ulceration: A Bisphosphonate Case in an Older Adult Care Setting.

Bisphosphonate-induced oral mucosal ulcers are rare adverse events distinct from medication-related osteonecrosis of the jaw. This case demonstrates successful conservative management through the modification of drug administration in an older adult care facility. A 91-year-old woman with dementia developed bilateral floor of the mouth and sublingual ulceration that persisted for 2 weeks. Histopathological examination excluded malignancy and confirmed a drug-induced etiology. Management involved correcting the minodronic acid administration technique without discontinuing therapy, which resulted in complete resolution within 4 weeks. This case underscores the importance of appropriate medication administration education and pharmacist involvement in the care of older adults to prevent and manage drug-related oral diseases.
