Colchicine/Cyclosporine Interactions

This information is generalized and not intended as specific medical advice. Consult your healthcare professional before taking or discontinuing any drug or commencing any course of treatment.

Medical warning:

Serious. These medicines may interact and cause very harmful effects. Contact your healthcare professional (e.g. doctor or pharmacist) for more information.

How the interaction occurs:

Cyclosporine may increase how much colchicine your body absorbs, and it may slow down how quickly your liver and kidneys processes colchicine. If you have familial Mediterranean fever (FMF), this interaction may occur more frequently or be worse.

What might happen:

The amount of colchicine in your blood may increase and cause toxic side effects. Deaths have been reported.

What you should do about this interaction:

Let your healthcare professionals (e.g. doctor or pharmacist) know right away that you are taking these medicines together or if you have taken cyclosporine in the previous 14 days.Make sure your doctor knows if you have any kidney or liver problems, which may make the interaction worse. Tell your doctor if you are receiving colchicine for FMF. Your doctor may need to change your medicine or the dose of your colchicine.Let your doctor know right away if you have vomiting; abdominal pain or nausea; severe diarrhea; any unexplained muscle weakness or pain; numbness or tingling in the fingers or toes; unusual bleeding or bruising; feeling weak or tired; increased infections; or pale or gray color of the lips, tongue, or palms of hands.Your healthcare professionals may already be aware of this interaction and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.
