On day 2 of her treatment, the patient complains of intense pain in her right great toe. On physical exam, the metatarsophalangeal joint of the 1st toe is warm, erythematous, swollen, and tender to both movement and palpation. An arthrocentesis is performed that reveals negatively birefringent needle-shaped crystals under polarized light. A Gram stain of the synovial fluid is negative. In addition to adequate intravenous hydration, which of the following if given would have most likely prevented the patient’s symptoms?
