What is Colcrys?
Colcrys (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.
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).
Colcrys is not a cure for gouty arthritis or Behcets syndrome, and it will not prevent these diseases from progressing. Colcrys should not be used as a routine pain medication for other conditions.
Serious drug interactions can occur when certain medicines are used together with Colcrys. Tell each of your healthcare providers about all medicines you use now, and any medicine you start or stop using.
Before taking Colcrys, tell your doctor if you have liver or kidney disease, heart disease, a stomach ulcer, ulcerative colitis, Crohn's disease, intestinal bleeding, or any other severe gastrointestinal disorder.
If you take Colcrys over a long period of time, your blood may need to be tested on a regular basis. Do not miss any scheduled appointments.
Call your doctor at once if you have a serious side effect such as muscle pain or weakness, numbness or tingly feeling in your fingers or toes, severe vomiting or diarrhea, easy bruising or bleeding, feeling weak or tired, flu symptoms, blood in your urine, urinating less than usual or not at all, or a pale or gray appearance of your lips, tongue, or hands.

Some medicines can cause unwanted or dangerous effects when used with Colcrys, 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:

itraconazole or ketoconazole; or
HIV or AIDS medicine - atazanavir, darunavir, fosamprenavir, indinavir, lopinavir, nelfinavir, ritonavir, or saquinavir.

Colcrys can be taken with or without food.
To treat a gout attack, for best results take Colcrys 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 Colcrys 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.

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, nausea, vomiting, stomach pain, muscle weakness, little or no urinating, numbness or tingling, weak pulse, slow heart rate, weak or shallow breathing, or fainting.

Grapefruit and grapefruit juice may interact with colchicine and lead to unwanted side effects. Avoid the use of grapefruit products while taking Colcrys.
