What is colchicine?

Colchicine is an oral medication, which is available as a generic and brand-name drug. Colchicine is a prescription drug. The generic form of this drug is usually less expensive than the branded ones. In certain cases, the generic ones may not be available in all of its strength or form as compared to the branded version.

Colchicine is used for the treatment of gout symptoms or attacks of familial Mediterranean fever. Familial Mediterranean fever is hereditary but noninfectious. It leads to a lot of pain and inflammation along with swelling in the lungs, joints, and abdominal region.

Colchicine is also used to prevent the symptoms of gout. Gout is a medical condition that occurs when uric acid crystals are formed and deposited in the joints. Colchicine can be used alone as a treatment or used as part of a combination therapy, which means taking colchicine along with other medications.
