1. What Penicillamine is and what it is taken for
Penicillamine belongs to a group of medicines called disease modifying antirheumatic drugs (DMARDS). DMARDS work by reducing the body’s immune response and the symptoms of rheumatoid arthritis.
Penicillamine helps to relieve the pain and stiffness caused by rheumatoid arthritis. It is used when other medicines for rheumatoid arthritis have not worked.
Penicillamine is also a chelating agent. This means that it binds to certain metals in your body, including lead and copper, to help remove them from your body.
Penicillamine is used in adults and children to treat:
- serious, active rheumatoid arthritis, including Still’s disease in children
- Wilson’s disease, a condition where the body cannot get rid of copper properly
- a kidney problem called cystinuria
- lead poisoning
Penicillamine is used in adults only to treat:
- chronic active hepatitis – a type of liver disease.
Penicillamine is not a painkiller so you should not expect to feel better straight away. It will be a few weeks before your joints feel less stiff and painful.
2. Check before you take Penicillamine
Your doctor will ask you to have blood tests to check your blood count and kidney function before you start taking penicillamine. He or she will test your blood and urine regularly while you are taking penicillamine. This is so that your doctor can check for any side effects and adjust your dose if necessary.
Do not take Penicillamine:
- if you are allergic (hypersensitive) to penicillamine or any of the ingredients of penicillamine (see Section 6 Further information)
- if you have ever had agranulocytosis (a low white blood cell count) after taking penicillamine
- if you have ever had aplastic anaemia (a severe reduction in blood cells which can cause weakness, bruising or make infections more likely) after taking penicillamine
- if you have ever had lupus erythematosus (LE). An allergic condition which causes skin rashes
- if you suffer from kidney problems
- if you have thrombocytopenia (a blood disorder which causes bleeding into your skin, bruising and more bleeding than usual after an injury) after taking penicillamine.
If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take penicillamine.
Take special care with Penicillamine
Before you take penicillamine tell your doctor:
- if you have ever had side effects with gold or you are currently taking medicines that contain gold
- if you have protein in your urine
- if you are pregnant, trying to become pregnant or breast-feeding
- if you have blood in your urine
- if you have leucopenia (a blood disorder which causes susceptibility to infection)
- if you are elderly.
If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take penicillamine.
Taking other medicines
Tell your doctor or pharmacist if you are taking or have recently taken/used any of the following medicines as they may interfere with penicillamine:
- gold – (used to treat rheumatoid arthritis) as there is an increased risk of getting side effects
- iron therapy – (used to treat low iron levels or anaemia) as the effect of penicillamine will be
reduced if taken with iron. Therefore take the iron at least two hours before or after taking penicillamine
- NSAIDs (Non-steroidal anti-inflammatory drugs) – e.g. ibuprofen or naproxen (used to treat arthritis and for pain relief) as there is an increased risk of) damaging your kidneys
- antacids – (used to neutralise acid in your stomach) as the effect of penicillamine will be reduced if taken with antacids. Therefore take the antacids at least two hours before or after taking Penicillamine.
- digoxin – (used for an irregular heartbeat) as the effect of digoxin will be reduced if taken with penicillamine.
- clozapine – (used to treat schizophrenia) as taking penicillamine with clozapine may increase the potential side effects on the bone marrow
- zinc – (used to treat low zinc levels) the effect of Penicillamine and/ or zinc will be reduced if taken together.
Please tell your doctor or pharmacist if you are taking or have recently taken/used any other medicines, including medicines obtained without a prescription.
Your doctor may give you pyridoxine (Vitamin B6) if you are taking pencillamine long term, especially if you are on a restricted diet.
Taking with food and drink
Penicillamine should be taken on an empty stomach, and at least half an hour (one hour for children with Wilson’s disease or cystinura) before a meal, with a drink of water.
Pregnancy and breast-feeding
Tell your doctor if you are pregnant, trying to become pregnant or are breast-feeding.
Ask your doctor or pharmacist for advice before taking any medicine.
3. how to take penicillamine
Always take penicillamine exactly as your doctor has told you to. You should check with your doctor or pharmacist if you are not sure.
When taking penicillamine:
- swallow the tablets with water
- always take your tablets at least half an hour before a meal, or at bedtime
- if you are taking iron tablets, antacids or digoxin, take them at least two hours before or after you have taken penicillamine
- take your tablets for as long as your doctor tells you to
- do not take more tablets than your doctor tells you to.
If you have kidney problems your doctor will start you on a lower dose.
You will have regular blood and urine tests, especially when you start taking the tablets and when you increase the dose. These are to check for changes in your blood cell counts and to look for protein or blood in your urine.
The usual dose for each condition is given below.
Adults
Take 125mg to 250mg a day for the first month. Your doctor will then tell you how to increase the dose gradually over several months until you are feeling better. Your doctor may then change your dose to keep you well. This new dose is usually 500mg to 750mg a day, but it can be as high as 1500mg.
It may be several months before you feel better. If there is no improvement after taking the tablets for 1 year, your doctor will tell you to stop taking the tablets. If you stay well for six months your doctor may reduce your dose.
Wilson’s disease:
Take 1500mg to 2000mg a day spread over three or four doses. Once you are better, your doctor may reduce your dose. It is best not to take 2000mg a day for more than a year.
Cystinuria:
If you have cystine stones your dose will be 1000mg to 3000mg a day. If you are taking the tablets to prevent stones you will take 500mg to 1000mg at bedtime.
Lead poisoning:
Take 1000mg to 1500mg a day in three or four doses until your doctor tells you that the amount of lead in your urine is normal.
Chronic active hepatitis:
Start with 500mg a day. Your doctor will gradually increase the dose over three months, to 1250mg a day.
The elderly
Take 125mg a day for the first month. Your doctor will then tell you how to increase the dose gradually over several months until you are feeling better. You should not take more than 1000mg in a single dose.
It may be several months before you feel better. If there is no improvement after taking the tablets for 1 year, your doctor will tell you to stop taking the tablets. If you stay well for six months your doctor may reduce your dose.
Wilson’s disease:
Your dose will depend on your weight. The usual dose is 20mg a day for each kilogram of body weight. Your doctor will reduce the dose over time to find the minimum necessary to control your disease.
Cystinuria:
Your doctor will determine your dose.
Lead poisoning:
Your dose will depend on your weight. The usual dose is 20mg a day for each kilogram of body weight until your doctor tells you the amount of lead in your blood is normal.
Children
The dose may depend on the weight of the child. As the smallest available tablet is 125mg, it might be too large for very small children.
Rheumatoid arthritis:
15mg to 20mg a day for each kilogram of body weight. You will start with a low dose for the first month and increase gradually.
Wilson’s disease:
For children under 12 years 20mg a day for each kilogram of body weight in two or three separate doses given 1 hour before meals.
For older children the usual dose is 0.75g to 1g daily.

15mg-20mg a day for each kilogram of body weight, in 2 or 3 separate doses.
If you are not sure how many tablets to take, ask your doctor or pharmacist or the staff at the hospital you visit for tests and treatment.

If you take too many tablets by mistake, or someone else takes any of your medicine by accident, you should tell your doctor at once or contact your nearest accident and emergency department. Show any left-over medicines or the empty packet to the doctor.
