Colchicine( Colchicine Prevent Sudden ) is used to prevent gout attacks in adults, sudden and severe pain in one or more joints caused by abnormally high levels of a substance called uric acid in the blood. Colchicine is also used to relieve pain when a gout attack occurs. Colchicine is also used to treat familial Mediterranean fever (FMF), a condition that causes episodes of fever, pain, stomach, lung, and joint swelling in adults and children over the age of four. Colchicine is not an analgesic and cannot be used to treat pain that is not caused by gout or FMF. Colchicine is part of a class of drugs called anti-gout agents. It works by stopping the natural processes that cause gout, swelling of FMF, and other symptoms.
