• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Medications such as ibuprofen or naproxen are commonly used to reduce pain and inflammation during acute gout attacks[4].
• Colchicine: This medication can be effective in treating acute gout flares and may also be used for prophylaxis in patients with recurrent attacks[5].

Corticosteroids

In cases where NSAIDs or colchicine are contraindicated or ineffective, corticosteroids (e.g., prednisone) may be prescribed to control inflammation and pain[6].

3. Uric Acid Lowering Therapy

For patients with recurrent gout attacks or chronic gout, uric acid-lowering therapy may be necessary. This typically involves:
- Allopurinol: A xanthine oxidase inhibitor that reduces uric acid production.
- Febuxostat: Another option for lowering uric acid levels, particularly in patients who cannot tolerate allopurinol[7].

4. Lifestyle Modifications

In addition to pharmacological treatments, lifestyle changes can play a significant role in managing gout:
- Dietary Adjustments: Patients are often advised to limit purine-rich foods (e.g., red meat, shellfish) and alcohol, which can exacerbate uric acid levels[8].
- Hydration: Increasing fluid intake helps dilute uric acid in the bloodstream and promotes its excretion through the kidneys[9].
- Weight Management: Maintaining a healthy weight can reduce the frequency of gout attacks and improve overall health.

5. Monitoring and Follow-Up

Regular follow-up appointments are essential to monitor uric acid levels and assess the effectiveness of treatment strategies. Adjustments to medication regimens may be necessary based on the patient's response and any side effects experienced[10].

Conclusion

Managing drug-induced gout, particularly when it affects the knee, involves a multifaceted approach that includes identifying and modifying causative medications, utilizing anti-inflammatory and uric acid-lowering therapies, and implementing lifestyle changes. Regular monitoring and follow-up care are crucial to ensure effective management and to prevent future gout attacks.
