Patient Education

Colchicine


Colchicine is used to prevent gout attacks (sudden, severe pain in one or more joints caused by abnormally high levels of a substance called uric acid in the blood) in adults. Colchicine (Colcrys) is also used to relieve the pain of gout attacks when they occur. Colchicine (Colcrys) is also used to treat familial Mediterranean fever (FMF; an inborn condition that causes episodes of fever, pain, and swelling of the stomach area, lungs, and joints) in adults and children 4 years of age and older. Colchicine is not a pain reliever and cannot be used to treat pain that is not caused by gout or FMF. Colchicine is in a class of medications called anti-gout agents. It works by stopping the natural processes that cause swelling and other symptoms of gout and FMF.
