Colchicine is a medication primarily used to treat gout and Mediterranean fever (FMF). It works by reducing inflammation in the body and preventing the formation of uric acid crystals in the joints, which can cause pain and swelling. Colchicine is a type of alkaloid derived from the Colchicum autumnale plant, commonly known as the autumn crocus. Colchicine acts by binding to tubulin and disrupting microtubule function, which in turn leads to the inhibition of leukocyte migration and cytokine production.

In dermatology, colchicine is also used to treat certain skin conditions, such as Behçet’s disease, Sweet’s syndrome, and pyoderma gangrenosum. It is believed to work by reducing inflammation in the skin, which can help alleviate symptoms such as skin lesions, blisters, and ulcers.

While colchicine is generally considered safe and effective, it can have side effects, particularly in high doses or with long-term use. These side effects may include nausea, vomiting, diarrhea, abdominal pain, and muscle weakness.
