1. What Colchicine Tablets are and what they are used for

The active ingredient in Colchicine Tablets is Colchicine.

In adults, Colchicine Tablets are used in the short term treatment of gout and to prevent attacks of gout from happening.

Uric acid is one of the body's waste products. In gout, crystals of uric acid are deposited in joints causing pain and inflammation.

Other medicines which are used to treat gout (like allopurinol or uricosuric drugs), take a long time to work and so colchicine can be used together with these drugs at the start of treatment.

In children, Colchicine Tablets are used in the treatment of Familial Mediterranean Fever for relief during attacks and to prevent a build up of proteins happening.

Familial Mediterranean Fever, is an inherited disease causing pain and swelling in the joints and body organs.

2. Before you take Colchicine Tablets

  • Think you may be allergic to Colchicine or to any of the other ingredients of Colchicine Tablets. (These are listed in section 6.);
  • You have a problem with your blood, e.g. leukaemia;
  • You have any problems with your liver;
  • You have any problems with your kidneys;

  • You are receiving vitamin B12 injections for anaemia. Colchicine may prevent the absorption of vitamin B12;
  • You are taking sympathomimetic drugs (e.g. to treat asthma or a blocked nose);

  • You are taking cyclosporin (a drug used to reduce the body's resistance to infection by suppressing the immune system.

3. How to take Colchicine Tablets

Colchicine is potentially toxic so it is important not to exceed the dose prescribed by your doctor.

You must take your tablets exactly as your doctor has told you 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.

If you take more colchicine tablets than you should; If you take more colchicine tablets than you are supposed to (or if you think a child has swallowed any), contact your doctor or nearest hospital accident and emergency department immediately. Take this leaflet and any colchicine tablets you have left with you.
