Colcrys (colchicine, USP) 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. Colchicine was developed prior to federal regulations requiring FDA review of drug products, not all uses for colchicine are approved by the FDA. As of 2009, Colcrys is the only brand of colchicine 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 (swelling, redness, warmth, and pain). Common side effects include diarrhea, nausea, cramping, abdominal pain, and vomiting.

The dosing regimens for Colcrys are different for each condition being treated, and must be individualized. Colcrys may interact with conivaptan, digoxin, diclofenac, imatinib, isoniazid, quinidine, antidepressants, antibiotics, antifungal medications, cholesterol-lowering medicines, heart or blood pressure medication, HIV or AIDS medication, or medicines used to prevent organ transplant rejection. Tell your doctor all medications you are taking. During pregnancy, Colcrys should be used only when prescribed. This medication passes into breast milk. While there have been no reports of harm to nursing infants, consult your doctor before breast-feeding.

Colcrys FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

Prophylaxis of Gout Flares

The most commonly reported adverse reaction in clinical trials of colchicine for the prophylaxis of gout was diarrhea.

Treatment of Gout Flares

The most common adverse reactions reported in the clinical trial with COLCRYS for treatment of gout flares were diarrhea (23%) and pharyngolaryngeal pain (3%).

FMF

Gastrointestinal tract adverse effects are the most frequent side effects in patients initiating COLCRYS, usually presenting within 24 hours, and occurring in up to 20% of patients given therapeutic doses. Typical symptoms include cramping, nausea, diarrhea, abdominal pain, and vomiting. These events should be viewed as dose-limiting if severe as they can herald the onset of more significant toxicity.

Clinical Trials Experience in Gout

Because clinical studies are conducted under widely varying and controlled conditions, adverse reaction rates observed in clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug, and may not predict the rates observed in a broader patient population in clinical practice.

In a randomized, double-blind, placebo-controlled trial in patients with a gout flare, gastrointestinal adverse reactions occurred in 26% of patients using the recommended dose (1.8 mg over 1 hour) of COLCRYS compared to 77% of patients taking a non-recommended high-dose (4.8 mg over 6 hours) of colchicine and 20% of patients taking placebo. Diarrhea was the most commonly reported drug-related gastrointestinal adverse event. As shown in Table 3, diarrhea is associated with COLCRYS treatment. Diarrhea was more likely to occur in patients taking the high-dose regimen than the low-dose regimen. Severe diarrhea occurred in 19% and vomiting occurred in 17% of patients taking the non-recommended high-dose colchicine regimen but did not occur in the recommended low-dose COLCRYS regimen.
