This article lists 27 drugs that can have life-threatening interactions with the widely-used gout drug, colchicine, resulting in dangerously elevated levels of colchicine.
Too much colchicine in the body leads to toxicity such as fever, vomiting, diarrhea, abdominal pain and muscle pains.
Even worse, it can impair the bone marrow’s ability to make red and white blood cells, causing severe anemia and dangerously low numbers of white blood cells.
