Colchicine is a medication primarily used to treat gout, a type of arthritis characterized by sudden and severe pain in the joints. It works by reducing inflammation and preventing the formation of uric acid crystals, which can cause painful flare-ups. Colchicine is often prescribed when other treatments are not effective or suitable. In addition to gout, colchicine may also be used for other conditions, such as familial Mediterranean fever, a genetic disorder that causes recurrent fevers and inflammation. It is important to use colchicine under medical supervision, as it can have side effects and interactions with other medications.
