Drug regimens for chronic gout
There is strong consensus that allopurinol should be used as first-line urate-lowering therapy. As a two-drug regimen, initially, for urate-lowering therapy and flare prophylaxis in chronic gout, use:
allopurinol 50 mg orally, daily; then increase the daily dose by 50 mg every 2 weeks or by 100 mg every 4 weeks up to a maximum daily dose of 900 mg to achieve the target serum uric acid concentration allopurinol allopurinol allopurinol
PLUS for flare prophylaxis
colchicine 500 micrograms orally, daily for at least 6 months. Reduce dosage in kidney impairment or in people who experience diarrhoea. colchicine colchicine colchicine
If a colchicine alternative is needed for flare prophylaxis, consider an NSAID or oral corticosteroids—see Prevention of gout flares when starting or changing urate-lowering therapy for drug choice. The duration of therapy should be individualised because long-term use can be associated with unacceptable adverse effects. Limit treatment to the lowest dose and shortest duration of treatment. For flare prophylaxis in chronic gout, use:
1celecoxib 100 to 200 mg orally, daily in 1 or 2 divided doses, until symptoms subside celecoxib celecoxib celecoxib
OR
1etoricoxib 30 to 60 mg orally, daily until symptoms subside etoricoxib etoricoxib etoricoxib
OR
1ibuprofen immediate-release 200 to 400 mg orally, 3 or 4 times daily until symptoms subside ibuprofen ibuprofen ibuprofen
OR
1indometacin 25 to 50 mg orally, 2 to 4 times daily until symptoms subside indometacin indometacin indometacin
OR
1ketoprofen modified-release 200 mg orally, daily until symptoms subside ketoprofen ketoprofen ketoprofen

2prednisolone (or prednisone) 5 mg orally, daily until symptoms subside. prednis ol one prednis(ol)one prednis(ol)one
If the target serum uric acid concentration is not achieved with allopurinol, check adherence before altering therapy because allopurinol therapy is rarely ineffective.
If the target serum uric acid concentration cannot be achieved despite adherence, probenecid (a weak uricosuric) may be added to allopurinol. For urate lowering therapy (in combination with allopurinol) for chronic gout, use:
probenecid 250 mg orally, twice daily for 1 week, then increase to 500 mg twice daily; then increase the daily dose by 500 mg every 4 weeks to achieve the target serum uric acid concentration. Maximum dose 2 g daily, in divided doses. probenecid probenecid probenecid
If allopurinol is contraindicated or not tolerated, replace allopurinol in the two drug regimen above with either:
1febuxostat 40 mg orally, daily for 2 to 4 weeks; then increase the daily dose by 40 mg every 2 to 4 weeks to achieve the target serum uric acid concentration. Maximum daily dose 120 mg1 febuxostat febuxostat febuxostat
OR
2probenecid 250 mg orally, twice daily for 1 week, then increase to 500 mg twice daily; then increase the daily dose by 500 mg every 4 weeks to achieve the target serum uric acid concentration. Maximum dose 2 g daily, in divided doses. probenecid probenecid probenecid
