What you should know about
Distamine

Please read this leaflet carefully before you start to take your medicine.  It does not contain all the information about your medicine that you may need to know.  Please ask your doctor or pharmacist if you have any questions.  This leaflet only applies to Distamine.

What is in your medicine?

Your medicine is called Distamine, a brand of penicillamine.  The active ingredient is D-penicillamine base.

The tablets come in two strengths (different sized tablets) containing 125mg and 250mg of the active ingredient, in bottles of 100 tablets.  They all have a white coating.  The 125mg tablets are 8mm across and are marked DS on one side and 125 on the other.  The 250mg tablets are 10mm across and are marked DM on one side and 250 on the other.

All the tablets contain the inactive ingredients microcrystalline cellulose, polyvidone, sodium starch glycolate and stearic acid.  The coating contains glycerol, E171 and methyl hydroxypropyl cellulose.

Distamine is a chelating agent.  This means that it binds to certain metals, including lead and copper, to help remove them from your body if necessary.  Distamine also helps to relieve the pain and stiffness of rheumatoid arthritis if other medicines and rest have not worked.

Distamine is made by Eli Lilly and Company Limited, Kingsclere Road, Basingstoke, Hampshire, RG21 6XA. The product licence is held by Dista Products Limited, Dextra Court, Chapel Hill, Basingstoke, Hampshire, RG21 5SY.

Why Distamine?

Distamine is used to treat serious, active rheumatoid arthritis, including Still’s disease in children.  It also treats Wilson’s disease, a condition where the body cannot get rid of copper properly; a kidney problem called cystinuria; lead poisoning; and chronic active hepatitis, a liver disease.

Before taking your medicine

Make sure it is safe for you to take Distamine,
If you answer YES to any of the following questions, or you are not sure, tell your doctor or pharmacist.

•	Have you ever had a rash or other allergic reaction to Distamine? (An allergic reaction may be a rash, itching, swelling or breathing difficulties.)
•	Have you ever had agranulocytosis (fever, mouth ulcers and severe weakness) after taking penicillamine?
•	Have you ever had thrombocytopenia (bruising and continual bleeding) after taking penicillamine?
•	Have you had lupus erythematosus (LE)?
•	Are you pregnant or could you be?
•	Are you taking any other medicine, especially for arthritis, including aspirin or a non-steroidal anti-inflammatory medicine (NSAID)?
•	Have you got kidney problems?
•	Your doctor will ask you to have a blood test and have your kidneys checked before you start taking Distamine.  He or she will test your blood and urine regularly while you are taking the medicine.  This is so that your doctor can adjust your dose and look out for any side-effects.
•	If you are taking iron tablets, take them at least 2 hours after you have taken the Distamine.
•	Distamine is not a painkiller so you should not expect to feel better straight away.  But after a few weeks you will feel better and your joints will be less stiff and painful.
•	Distamine can help to treat rheumatoid arthritis but not other kinds of arthritis.

If you have these or any other ill-effects, tell your doctor or the staff at your outpatient clinic.  They have more information about Distamine and will tell you what to do.  They may tell you to reduce your dose for a time. or to stop it altogether.
