Regarding [[medication]]s, if there are no mitigating factors in choosing a drug, [[glucocorticoid]]s, [[non-steroidal anti-inflammatory agent]]s (NSAIDs), and [[colchicine]] all work; however, [[colchicine]] consistently causes [[drug toxicity]].
A combination treatment is ice four times a day with oral prednisone 30 mg orally tapered over 6 days (30 mg for two days, 20 mg for two days, 10 mg for two days) and colchicine 0.6 mg/day.<ref name="pmid11838852">{{cite journal |author=Schlesinger N, Detry MA, Holland BK, ''et al'' |title=Local ice therapy during bouts of acute gouty arthritis |journal=J.

===Non-steroidal anti-inflammatory agents===
[[Non-steroidal anti-inflammatory agent]]s (NSAIDs) are better than placebo according to a [[randomized controlled trial]] of 30 total patients.<ref>García de la Torre, Ignacio.

After 24 h, 67% of tenoxicam group had ≥50% reduction in pain compared with 26% of placebo group (P<0.05). However, at the end of the treatment (4 days), there was no significant difference between the groups."<ref name="pmid16632483">{{cite journal |author=Sutaria S, Katbamna R, Underwood M |title=Effectiveness of interventions for the treatment of acute and prevention of recurrent gout--a systematic review |journal=Rheumatology (Oxford) |volume=45 |issue=11 |pages=1422–31 |year=2006 |month=November |pmid=16632483 |doi=10.1093/rheumatology/kel071 |url=http://rheumatology.oxfordjournals.org/cgi/pmidlookup?view=long&pmid=16632483 |issn=}}</ref>

|colspan="5"|Notes:<br/>
† Clinical diagnosis of gout was "pain and warmth in a joint, and presented within 3 days of the onset of pain and also had 1 or more of the following: metatarsal-phalangeal joint involvement; knee or ankle joint involvement and aspirate containing crystals; or typical gouty arthritis, with either gouty tophi present or previous joint aspiration confirming the diagnosis of gout." Seven patients allowed arthrocentesis and all were positive for gout.

[[Randomized controlled trial]]s find similar benefit from [[non-steroidal anti-inflammatory agent]]s and oral [[glucocorticoid]]s. In the first trial the reduction in [[pain measurement|visual analog scale]] after 5 days was 44.7 with [[prednisolone]] and 46.0 with [[naproxen]].<ref name="pmid17276548">{{cite journal |author=Man CY, Cheung IT, Cameron PA, Rainer TH |title=Comparison of oral prednisolone/paracetamol and oral indomethacin/paracetamol combination therapy in the treatment of acute gout-like arthritis: a double-blind, randomized, controlled trial |journal=Annals of emergency medicine |volume=49 |issue=5 |pages=670–7 |year=2007 |pmid=17276548 |doi=10.1016/j.annemergmed.2006.11.014}}</ref> Less [[adverse drug reaction]]s occurred in the [[glucocorticoid]]s group; however, the NSAID group received a high dose (50 mg every 8 hours for 2 days, followed by 25 mg every 8 hours for 3 days)<ref name="pmid8664664">{{cite journal |author=Henry D, Lim LL, Garcia Rodriguez LA, ''et al'' |title=Variability in risk of gastrointestinal complications with individual non-steroidal anti-inflammatory drugs: results of a collaborative meta-analysis |journal=BMJ |volume=312 |issue=7046 |pages=1563–6 |year=1996 |month=June |pmid=8664664 |pmc=2351326 |doi= |url=http://bmj.com/cgi/pmidlookup?view=long&pmid=8664664 |issn=}}</ref>.
In the second [[randomized controlled trial]] statistically equal effect resulted from prednisolone 35 mg orally per day or naproxen 500 mg orally twice per day; however there was an insignificant 8% improvement in the NSAID group.<ref name="pmid18514729">{{cite journal |author=Janssens HJ, Janssen M, van de Lisdonk EH, van Riel PL, van Weel C |title=Use of oral prednisolone or naproxen for the treatment of gout arthritis: a double-blind, randomised equivalence trial |journal=Lancet |volume=371 |issue=9627 |pages=1854–60 |year=2008 |month=May |pmid=18514729 |doi=10.1016/S0140-6736(08)60799-0 |url=http://linkinghub.elsevier.com/retrieve/pii/S0140-6736(08)60799-0 |issn=}}</ref> There were no significant differences in [[drug toxicity]].
===Colchicine===
[[Colchicine]] is better than placebo according to a [[systematic review]] by the [[Cochrane Collaboration]]<ref name="pmid17054279">{{cite journal |author=Schlesinger N, Schumacher R, Catton M, Maxwell L |title=Colchicine for acute gout |journal=Cochrane Database Syst Rev |volume= |issue=4 |pages=CD006190 |year=2006 |pmid=17054279 |doi=10.1002/14651858.CD006190 |url=http://dx.doi.org/10.1002/14651858.CD006190 |issn=}}</ref> that found a single [[randomized controlled trial]] of 43 patients<ref name="pmid3314832">{{cite journal |author=Ahern MJ, Reid C, Gordon TP, McCredie M, Brooks PM, Jones M |title=Does colchicine work?

In this study, colchicine 1 mg orally, followed by 0.5 mg every two hours led to a 50% reduction in pain in about 70% of patients compared to about 35% of patients who received placebo. However, all patients had [[drug toxicity]] from colchicine and in 90% of the patients toxicity occurred before 50% reduction in pain.
Regarding the best dose, 1.2 mg followed by 0.6 mg in 1 hour may be as effective as higher dose.<ref name="pmid20131255">{{cite journal| author=Terkeltaub RA, Furst DE, Bennett K, Kook KA, Crockett RS, Davis MW| title=High versus low dosing of oral colchicine for early acute gout flare: Twenty-four-hour outcome of the first multicenter, randomized, double-blind, placebo-controlled, parallel-group, dose-comparison colchicine study. | journal=Arthritis Rheum | year= 2010 | volume= 62 | issue= 4 | pages= 1060-8 | pmid=20131255

To avoid [[drug toxicity]], lower doses of colchicine (0.6 per day) have been used in combination with [[glucocorticoid]]s.<ref name="pmid11838852">{{cite journal |author=Schlesinger N, Detry MA, Holland BK, ''et al'' |title=Local ice therapy during bouts of acute gouty arthritis |journal=J.
