From the Guidelines
For acute gout attacks, colchicine should be taken as soon as symptoms begin, with a recommended dose of 1 mg initially, followed by 0.5 mg one hour later, and for prevention of gout flares, colchicine is typically taken at a lower dose of 0.5-1 mg/day for 6 months. The duration of colchicine therapy for acute gout attacks is usually short, lasting 1-3 days until symptoms improve, with a total dose not exceeding 1.8 mg in the first 12 hours of treatment 1. For preventative treatment, the recommended duration is typically 6 months, with a dose of 0.5-1 mg/day, which may be adjusted based on renal impairment or other factors 1. It's essential to note that colchicine has potential side effects, including gastrointestinal symptoms, and interactions with other medications, such as antibiotics and statins, which should be considered when prescribing this medication 1. Key points to consider when prescribing colchicine include:
- Starting dose for acute gout attacks: 1 mg initially, followed by 0.5 mg one hour later
- Duration of therapy for acute gout attacks: 1-3 days
- Dose for preventative treatment: 0.5-1 mg/day
- Duration of preventative treatment: typically 6 months
- Potential side effects: gastrointestinal symptoms, interactions with other medications
- Necessary adjustments: dose adjustments for patients with kidney or liver impairment, consideration of drug interactions.

From the Research
Duration of Colchicine Therapy
There are no research papers to assist in answering this question, as the provided studies focus on the treatment of gallstones and chronic liver disease with ursodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA), rather than colchicine therapy.
Relevant Information on UDCA Therapy
- The duration of UDCA therapy for gallstone dissolution ranged from 5 to 16 months 3.
- Treatment with UDCA for approximately one year reduced the high levels of hydroxymethylglutaryl coenzyme A reductase in gallstone patients 4.
- Patients receiving UDCA for dissolution of gallstones showed improvement in symptoms of biliary distress after three to six weeks 4.
- UDCA therapy was given at dosages of 250,500, and 750 mg/day for consecutive periods of two months in patients with primary biliary cirrhosis, primary sclerosing cholangitis, and chronic hepatitis 5.
No Information on Colchicine
No information is available on the duration of colchicine therapy for acute and preventative treatment, as the provided studies do not mention colchicine.
