Actual product appearance may differ slightly.
What is Colcrys?
Colcrys (colchicine) affects the way the body responds to uric acid crystals, which reduces swelling and pain.
Because colchicine was developed prior to federal regulations requiring FDA review of all marketed drug products, not all uses for colchicine have been approved by the FDA. As of 2009, Colcrys is the only brand of colchicine that has been approved by the FDA.
Colcrys is FDA-approved to treat gout in adults, and to treat a genetic condition called Familial Mediterranean Fever in adults and children who are at least 4 years old.
Generic forms of colchicine have been used to treat or prevent attacks of gout, or to treat symptoms of Behcets syndrome (such as swelling, redness, warmth, and pain).
Colchicine is not a cure for gouty arthritis or Behcets syndrome, and it will not prevent these diseases from progressing. Colcrys should not be used as a routine pain medication for other conditions.
