A
  1. Corticosteroids

Controls most attacks, significant relief:

Oral, IV, IM or intra-articular. (Since gout and and septic arthritis can coexist, joint aspiration, Gram stain, culture should be done first).

Primary objective:

Reduce inflammation

Reduce pain

Preservation function

Prevent deformity
