Oral bisphosphonates-associated osteonecrosis in rheumatoid arthritis

Adverse effects associated with the use of bisphosphonates are infrequent and consist of pyrexia, renal function impairment, and hypocalcemia. Bisphosphonates-associated osteonecrosis of the jaws is an uncommon but potentially serious complication of intravenous bisphosphonate therapy in cancer patients. The degree of risk for osteonecrosis in patients taking oral bisphosphonates, such as alendronate, is uncertain and warrants careful monitoring. Oral bisphosphonates-associated osteonecrosis can occur in patients with rheumatoid arthritis. We report a case of mandibular osteonecrosis in a patient who received alendronate for 3.8 years. The pathology improved after bisphosphonate therapy dis…
