the start of treatment.

to. The dose will be on the pharmacist’s label. Check the label
carefully. It should tell you how many tablets to take and how
often. If you are not sure, ask your doctor or pharmacist.
Swallow the tablets whole with water.

The following doses are intended as a guide:
Treating acute gout: The most common dose for the
treatment of gout in adults is 1mg (2 tablets) to start then
500mcg (1 tablet) every 4 hours until the pain is better or
you feel sick or diarrhoea occurs. Up to 6mg (12 tablets)
can be taken altogether. You should not take treatment
again until at least 3 days have passed.
To help prevent attacks of gout: 500mcg (1 tablet) each week
may be enough, or 500mcg (1 tablet) 2 - 3 times a day.
To prevent gout happening again or to prevent gout at the
start of treatment with other medicines (eg. Allopurinol):
Take 500mcg (1 tablet) 2-3 times a day.
If you are elderly, or have kidney problems, you may need a
lower dose.
In children with Familial Mediterranean fever the
recommended dose is based on age. The following daily
doses may be given as a single dose or divided dose twice
daily (for doses over 1mg/day);
• Children less than 5 years of age; 0.5 mg/day
• Children 5 to 10 years of age: 1 mg/day
• Children more than 10 years of age: 1.5 mg/day
Colchicine dosage should be increased in a stepwise fashion
(0.25 mg/step) up to a maximum of 2 mg/day. Any increase
of the dose should be monitored closely for adverse effects.
If you forget to take a dose at the right time, take it as soon
as you remember. Do not take two doses together.
