Suggest Treatment For Gout Pain

I recently had a Gout attack and saw a phisician. I was given an injection in the arm of Steroid and given a prescription for Indomethacin 50 mg 60 caplets with 2 refills. Directions with the prescription instructed me to take 1 caplet twice a day as needed. 2 days after the injection and taking the drug, there is noticible improvement. Is there a minimum amount of days I should continue to take the prescription or as soon I feel complete relief should I discontinue use?
