What are the risks of taking colchicine (Colcrys)?

Do not take lisinopril or any ACE inhibitor if you are pregnant or actively trying to conceive.

Colchicine can cause serious health complications in some people. Talk to your healthcare provider or pharmacist if these risks are a concern.

Other risks of colchicine (Colcrys) use include:

Overdose: An accidental or intentional colchicine overdose can be fatal in adults and children. Take this medicine exactly as directed by your doctor. Keep all medications, including colchicine, in a safe place, out of reach of children.
Blood Cell Formation: Colchicine can reduce the body’s ability to make blood cells. This risk is present even when you take colchicine at the recommended dose. It can be a serious problem if it is not identified in time. Keep all your doctors’ appointments and get regular labs done as advised. Tell your healthcare provider immediately if you notice any unusual bruising or bleeding, fever, or unexplained tiredness.
Drug Interactions: There can be drug interactions between colchicine and other medicines. Taking colchicine with other drugs can lead to dangerous adverse effects. Drug interactions can be more serious in people with renal or hepatic impairment (kidney or liver problems). Make sure you give your healthcare provider a complete list of your medications. Besides drug interactions, colchicine can also interact with certain foods. Eating grapefruit or drinking grapefruit juice can increase the amount of colchicine in your body. This can increase the risk of adverse effects and colchicine toxicity.

Speak to your doctor or pharmacist about other treatment options if you are at high risk for the above complications.
