How does this medication work? What will it do for me?
Colchicine is a medication used to treat gout and prevent frequently occurring attacks of gout. Gout is a form of arthritis that occurs when too much uric acid builds up in the body because the body is unable to get rid of it quickly enough. Colchicine works by reducing the swelling, inflammation, and pain that occurs when uric acid crystals form in the joints.
Colchicine may also be used to prevent attacks of gout at the same time as other medications for gout are being used, such as probenecid, sulfinpyrazone, or allopurinol.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
