Colcrys



Generic Name: colchicine (KOL chi seen)

Brand Names: Colcrys


What is colchicine?

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. As of 2009, Colcrys is the only brand of colchicine that has been approved by the FDA.

The Colcrys brand of colchicine is FDA-approved to treat gout in adults, and to treat a genetic condition called Familial Mediterranean Fever in adults and children who are at least 4 years old.


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.

How should I take colchicine?


If your doctor has prescribed the Colcrys brand of colchicine, do not use any other type or brand of the medication. Colcrys is the only brand of colchicine that has been approved by the FDA. If you use a generic brand of colchicine, you may be using an unapproved dose of this medication, which could be dangerous. Do not purchase colchicine on the Internet or from vendors outside of the United States. Using this medication improperly or without the advice of a doctor can result in serious side effects or death.

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.


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 medication. Colchicine doses for gout and Mediterranean fever are different.

If you use this medication over a long period of time, your blood may need to be tested on a regular basis. Do not miss any scheduled appointments.


Keep using colchicine as directed, even if you feel well. Tell your doctor if the medicine seems to stop working as well in preventing gout attacks. Do not stop using colchicine without first talking to your doctor.


Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?


Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of colchicine can be fatal.

Overdose symptoms may include diarrhea (may be bloody and severe), nausea, vomiting, stomach pain, heartburn, a burning feeling in your throat or stomach, muscle weakness, urinating less than usual, numbness or tingling, fainting, or seizure (convulsions).


What should I avoid while taking colchicine?
