What does it do?

Penicillamine is used to treat rheumatoid arthritis and sometimes other conditions.

Before you start

  • Tell your doctor if you have kidney or blood problems, or if you have ever had an allergic reaction to penicillin or any other medicine.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take penicillamine with a glass of water on an empty stomach (at least one hour before or 2 hours after food). Do not take with milk.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with penicillamine including:

  • anti-inflammatories, such as diclofenac (e.g. Voltaren®) or ibuprofen (e.g. Nurofen®). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
  • antacids (e.g. Mylanta®)
  • mineral supplements including calcium (e.g. Calci-Tab®), iron (e.g. Ferro-Tab®), zinc (e.g. Zincaps®) and magnesium
