Treatment of chronic gouty arthritis when complicated by frequent, recurrent acute attacks of gout
Hypersensitivity to colchicine, probenecid, or any component of the formulation; children <2 years of age; small- or large-dose aspirin therapy; blood dyscrasias; uric acid kidney stones; initiation during an acute gout attack; concomitant use of a P-glycoprotein (P-gp) or strong CYP3A4 inhibitor in presence of renal or hepatic impairment
Gout: Oral: One tablet/day for 1 week, then 1 tablet twice daily thereafter
Note: Current prescribing information states a maximum dose of 4 tablets per day; however this exceeds the usual maximum dose of colchicine for gout prophylaxis (1.2 mg per day).
Refer to adult dosing.
Clcr <30 mL/minute: Probenecid may not be effective in patients with chronic renal insufficiency.
No dosage adjustment provided in manufacturers labeling; use with caution.
Do not initiate therapy until acute attack has subsided.
Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience dizziness, headache, flushing, lack of appetite, nausea, vomiting, or hair loss. Have patient report immediately to prescriber burning or numbness feeling, severe diarrhea, back pain, abdominal pain, blood in urine, urinary retention, change in amount of urine passed, bruising, bleeding, severe loss of strength and energy, muscle pain, or muscle weakness (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
