Important Safety Information

COLCRYS^® (colchicine, USP) tablets are used to prevent and treat gout flares.

COLCRYS can cause serious side effects in people with kidney or liver problems who are taking medicines that interfere with COLCRYS. COLCRYS can also cause serious muscle problems. You have a higher chance for muscle problems if you are taking certain other medicines with COLCRYS. Certain medicines when taken with COLCRYS can cause the levels of COLCRYS to be too high in your body. Discuss any health problems you have, as well as medicines you are taking (including non-prescription medications and herbal supplements), with your healthcare provider before starting COLCRYS. The most common side effect in clinical trials for the prevention and treatment of gout was diarrhea.
