Fexofenadine As Successful Adjunctive Treatment of Rheumatoid Arthritis and Trochanteric Bursitis: A Case Report.

Rheumatoid arthritis (RA) is a chronic inflammatory joint disease that results in cartilage and bone damage, primarily involving synovial joints. The hallmark feature of this condition is inflammatory polyarthritis which can be associated with other joint pathologies, including bursitis. Many treatment options help relieve joint pain and slow down damage to the joints in both RA and bursitis. However, not all treatments are effective or affordable. These treatments include non-steroidal anti-inflammatory drugs (NSAIDs), biologic disease-modifying antirheumatic drugs (bDMARDS), conventional DMARDS (cDMARDS), and corticosteroids. This is a case of trochanteric bursitis in the setting of RA, which was subjectively and objectively treated using the histamine receptor antagonist fexofenadine.
