Colchicine is used to treat a gout attack (flare)

Colchicine is used to relieve pain and swelling when you have gout flares (attacks). It works by reducing the build-up of uric acid crystals in the affected joints and by reducing your body’s inflammatory reaction to the uric acid crystals in the affected joint. This reduces pain and swelling. Colchicine works best if you take it at the first sign of gout pain, redness and swelling. Read more about gout and medicines for gout.


Colchicine is used to prevent gout attacks when you are starting allopurinol or febuxostat

Colchicine is also used to prevent gout attacks while starting on urate-lowering therapy such as allopurinol or febuxostat. These medicines limit the amount of uric acid your body makes. When starting them, it’s common to have gout flare-ups as they start to dissolve some of the uric acid crystals in your joints. To prevent these flare ups it's recommended you take colchicine for the first 3 to 6 months of starting allopurinol or febuxostat, until your target serum urate level has been reached. It's important to take colchicine regularly during this time because gout flares can occur soon after stopping colchicine prophylaxis.

Keep medication out of reach of children

Store colchicine out of reach of children – as little as 1 or 2 tablets may be fatal for children.
  • If children live with you or visit your house, ask your pharmacist to put a child safety cap on your medicine bottle. Make sure the cap is relocked after each use.
  • Some children may still be able to open the container, so make sure you also store the medicine out of sight and reach of children.
  • Store medicines in a locked cupboard or somewhere that your child cannot reach or access them.
  • Always return unused or expired medicines to your local pharmacy for disposal.

In Aotearoa New Zealand, colchicine is available as 0.5 mg tablets. 

  • The pharmacy label on your medicine will tell you how much colchicine to take, how often to take it and any special instructions.
  • Never take more than the prescribed dose.
  • Taking too much colchicine can cause serious side effects.


Dose to treat a gout attack (flare)

Colchicine works best if you take it at the first sign of gout pain, redness and swelling.

  • Take 2 tablets straight away, followed by 1 tablet one hour later. Don't repeat this course within 3 days.
  • If you get nausea (feeling sick) or runny poos (diarrhoea), stop taking colchicine.


Dose to prevent gout attacks when you are starting allopurinol or febuxostat

  • The usual dose is: 1 tablet once a day. 
    For some people, their dose may be increased to 1 tablet 2 times a day if they are still having gout flares. 
  • If you get diarrhoea (runny poo) from taking colchicine your prescriber may lower your dose to 1 tablet on alternate days (every other day).
  • When you start allopurinol or febuxostat, it's recommended you take colchicine for 3 to 6 months, until your target serum urate level has been reached. 
  • It's important to take colchicine regularly during this time because gout flares can occur soon after stopping colchicine prophylaxis.
  • If you're taking colchicine regularly to prevent an attack, but have an attack and need a treatment dose, have the treatment then wait 12 hours before re-starting your regular colchicine dose.

Extra care is needed when taking colchicine

  • Most people who take colchicine have no problems but extra care is needed when taking it.
  • Colchicine is considered a high-risk medicine because it can cause serious side effects. There isn’t a big difference between a safe dose of colchicine and a harmful dose. People who are over 65 years of age or have kidney or liver problems are especially at risk.
  • This means you must always take colchicine exactly as your doctor has told you to.
  • See below for signs you may be taking too much colchicine

  • Swallow your tablet whole with a full glass of water.
  • Take it with food to reduce stomach upset.
  • If you have taken colchicine to treat a gout attack in the last 3 days, don't start another course. Discuss with your doctor first.

Here are some things to know when you're taking colchicine. Other things may be important as well, so ask your healthcare provider what you should know about.

  • Alcohol: Avoid drinking alcohol as it can cause stomach problems. 
  • Grapefruit and grapefruit juice: Don't drink grapefruit juice as it increases the risk of side effects.
  • Taking other medicines: Colchicine interacts with some medicines and herbal supplements, so check with your doctor or pharmacist before starting colchicine or before starting any new medicines. This includes those you may buy over the counter.

Colchicine can cause serious side effects, although not everyone gets them.
