Colchicine (Brand: Colcrys) is an alkaloid used to prevent or treat gout attacks (flares), and is also used to prevent attacks of pain in the abdomen, chest, or joints caused by a certain inherited disease (familial Mediterranean fever). Common side effects of Colchicine include diarrhea, nausea, cramping, abdominal pain, and vomiting. Contact your doctor if you experience rare but serious side effects including unusual bleeding/bruising, muscle weakness or pain, numbness/tingling in your fingers or toes, pale or gray color of the lips/tongue/palms of hands, signs of infection (such as fever, persistent sore throat), fast heartbeat, or shortness of breath.
To treat acute gouty arthritis the usual dose of colchicine to relieve or abort an attack is 1 to 1.2 mg (two 0.5 mg granules or two 0.6 mg tablets). This dose may be followed by one unit of either preparation (granule or tablet) every hour, or two units every two hours, until pain is relieved or until diarrhea ensues. Colchicine may interact with azole antifungals, cyclosporine, HIV medications, antibiotics, telithromycin, verapamil, atorvastatin, digoxin, gemfibrozil, fenofibrate, pravastatin, or simvastatin. Tell your doctor all medications and supplements you use. During pregnancy, colchicine should be used only when prescribed. This medication passes into breast milk. While there have been no reports of harm to nursing infants, consult your doctor before breastfeeding.
