Reactive arthritis (ICD-10 M02.3; ICD-11 FA11.2) is an inflammatory joint condition that frequently follows a self-limiting course. Initial management is directed at controlling acute inflammation and enabling patients to remain physically active while the condition resolves.
NSAIDs are the cornerstone of first-line pharmacologic management in acute reactive arthritis. The choice of specific agent — and the structured duration for which it is used — depends on the individual patient's clinical profile. The full protocol specifies how long to trial an agent before reassessing, which factors guide agent selection, and how to proceed when the initial choice is insufficient.
