HOW TO USE THIS INFORMATION: This is a summary and does NOT have all possible information about this product.

This medication is used to prevent or treat gout attacks (flares). Usually gout symptoms develop suddenly and involve only one or a few joints. The big toe, knee, or ankle joints are most often affected. Gout is caused by too much uric acid in the blood. When uric acid levels in the blood are too high, the uric acid may form hard crystals in your joints. Colchicine works by decreasing swelling and lessening the build up of uric acid crystals that cause pain in the affected joint(s). This medication is also used to prevent attacks of pain in the abdomen, chest, or joints caused by a certain inherited disease (familial Mediterranean fever). It is thought to work by decreasing your body’s production of a certain protein (amyloid A) that builds up in people with familial Mediterranean fever. Colchicine is not a pain medication and should not be used to relieve other causes of pain.
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. This medication may also be used to reduce swelling and inflammation of the sac that covers the outside of the heart, a condition called pericarditis.

If you are taking this medication to treat a gout attack, carefully follow the directions given by your doctor.
This medication works best if you take it at the first sign of an attack. The recommended dose is 1.2 milligrams at the first sign of an attack, followed by 0.6 milligrams one hour later. The maximum recommended dose is 1.8 milligrams taken over a 1-hour period. Ask your doctor ahead of time about how soon you can repeat treatment with this medication if you have another gout attack. If you are taking this medication to prevent gout attacks or for pericarditis, ask your doctor about the dose and schedule you should follow. Carefully follow your doctor’s directions.

Serious side effects may occur even at usual prescribed doses. If your doctor directs you to take colchicine regularly, use it regularly to get the most benefit from it.

See also How to Use and Precautions sections. The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.

While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor’s approval. Other medications can affect the removal of colchicine from your body, which may affect how colchicine works or increase the risk of serious side effects. Examples include certain azole antifungals (such as itraconazole, ketoconazole), diltiazem, HIV medications (such as ritonavir), macrolide antibiotics (such as clarithromycin, erythromycin), telithromycin, verapamil, among others. Colchicine may rarely cause a certain serious (even fatal) muscle damage (rhabdomyolysis). This muscle damage releases substances that can lead to serious kidney problems.
The risk may be increased if other drugs that may also cause rhabdomyolysis are taken along with colchicine. Some affected drugs include: atorvastatin, digoxin, gemfibrozil, pravastatin, simvastatin, among others.
