Drug Information:
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. The Colcrys brand of Colchicine 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.
