What is Colchicine for?
Colchicine is a medicine for treating and preventing gout attack as well as familial Mediterranean fever. It works by preventing the accumulation of uric acid crystals and hence relieving pain and also stopping the process that results in swelling.
Colchicine does not cure gout, but is used to treat and prevent gout attacks.
How to use it?
Colchicine can be taken by mouth as tablets. For the acute treatment of gout flares, the usual dose on day 1 is 1 mg (or 1.2 mg) once, followed in one hour by 0.5 mg (or 0.6 mg) once. An alternative dosing regimen is 0.5 mg (or 0.6 mg) 3 times daily. On day 2, you then would take 0.5 mg (or 0.6 mg) once or twice daily. Many people continue this dose until the flare is resolved or for 2-3 days after the flare resolves. For the prevention of gout when starting antigout agents like Allopurinol, doses range from 0.5 mg (or 0.6 mg) once or twice daily. For the prevention of attacks in familial Mediterranean fever, dosages are usually 0.5-3 mg once daily.
