From the Guidelines
Colchicine should be prescribed for acute gout attacks at a dose of 1.2 mg initially, followed by 0.6 mg one hour later, as this regimen has been shown to be effective and well-tolerated in clinical trials 1. When prescribing colchicine for gout treatment, it is essential to consider the patient's renal function and adjust the dose accordingly.
- For patients with normal kidney function, the recommended dose is 1.2 mg initially, followed by 0.6 mg one hour later.
- For patients with moderate to severe chronic kidney disease (CKD), the dose should be reduced, and colchicine should be used with caution. Some key points to consider when prescribing colchicine include:
- Treatment should begin at the first sign of a gout attack for maximum effectiveness.
- Patients with kidney or liver impairment require dose adjustments, and colchicine should be used cautiously in these populations.
- Common side effects include diarrhea, nausea, and abdominal pain, which can be minimized by starting with lower doses.
- Colchicine works by reducing inflammation associated with gout attacks by inhibiting neutrophil migration and activity, thereby decreasing the inflammatory response to urate crystals in joints.
- It should not be used with certain medications like strong CYP3A4 inhibitors (e.g., clarithromycin) or P-glycoprotein inhibitors due to potential serious interactions, as noted in the 2012 American College of Rheumatology guidelines for management of gout 1. Patients should be advised to stay well-hydrated and avoid alcohol during treatment to help manage gout symptoms, as recommended by the 2016 updated EULAR evidence-based recommendations for the management of gout 1.

From the Research
Prescribing Colchicine for Gout Treatment
- Colchicine is an effective treatment for acute gout, with low-dose colchicine being better tolerated than high-dose colchicine 3, 4
- The recommended dose of colchicine for acute gout is 1.8 mg over 1 hour, taken as early as possible 4
- Colchicine can be used as a second-line therapy when NSAIDs or corticosteroids are contraindicated or ineffective 5
- Low-dose colchicine has been shown to have a comparable efficacy to NSAIDs in the treatment of acute gout, with a similar side effect profile 3, 6
Administration and Dosage
- Colchicine should be taken at the first sign of a gout attack, with the goal of reducing pain and inflammation 4
- The dose of colchicine can be adjusted based on the patient's response and tolerance, with a maximum dose of 1.8 mg over 1 hour 4
- Colchicine can be used in combination with other medications, such as NSAIDs or corticosteroids, for the treatment of acute gout 6
Safety and Efficacy
- Colchicine has a narrow therapeutic-toxicity window, and patients should be monitored for signs of toxicity, such as gastrointestinal side effects 5, 4
- Low-dose colchicine has been shown to be well-tolerated, with a lower risk of adverse events compared to high-dose colchicine 3, 4
- Colchicine is effective in reducing pain and inflammation in patients with acute gout, with a rapid onset of action 5, 4
