| Probenecid | Effective for urinary uric acid excretion | Headache, GI upset | $20-$50 |
Healthcare trends indicate a preference among some doctors for Febuxostat when patients exhibit difficulty tolerating Allopurinol. This shift is often based on individual patient response and risk factors. Therefore, many practitioners assess the patient's specific needs before deciding on the best treatment approach.
