Serious drug interactions can occur when certain medicines are used together with colchicine. Tell each of your healthcare providers about all medicines you use now, and any medicine you start or stop using.
Colchicine affects the way the body responds to uric acid crystals, which reduces swelling and pain.
Because colchicine was developed prior to federal regulations requiring FDA review of all marketed drug products, not all uses for colchicine have been approved by the FDA.
The Colcrys brand of colchicine is FDA-approved to treat or prevent gout in adults, and to treat a genetic condition called Familial Mediterranean Fever in adults and children who are at least 4 years old.
The Mitigare brand of colchicine is FDA-approved to prevent gout flares in adults.
Generic forms of colchicine have been used to treat or prevent attacks of gout, or to treat symptoms of Behcets syndrome (such as swelling, redness, warmth, and pain).
Colchicine is not a cure for gouty arthritis or Behcets syndrome, and it will not prevent these diseases from progressing. Colchicine should not be used as a routine pain medication for other conditions.
Colchicine may also be used for purposes not listed in this medication guide.
You should not use colchicine if you are allergic to it.
Some medicines can cause unwanted or dangerous effects when used with colchicine, especially if you have liver or kidney disease. Your doctor may need to change your treatment plan if you use any of the following drugs:

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Colchicine can be taken with or without food.
To treat a gout attack, for best results take colchicine at the first sign of the attack. The longer you wait to start taking the medication, the less effective it may be.
You may need to take a second lower dose of colchicine 1 hour after the first dose if you still have gout pain. Follow your doctor's instructions.
Your dose will depend on the reason you are taking this medicine. Colchicine doses for gout and Mediterranean fever are different.
Do not stop using colchicine unless your doctor tells you to, even if you feel fine.
Call your doctor if your symptoms do not improve, or if they get worse.
