Penicillamine for Rheumatoid Arthritis
Penicillamine is given orally, in capsule or tablet form.
How It Works
Penicillamine reduces inflammation from rheumatoid arthritis and slows progression of the disease. Penicillamine is a substance that normally is used to bind and remove metals and toxic chemicals from the blood.
Why It Is Used
Penicillamine may be used when rheumatoid arthritis is not controlled by other medicines. Rheumatologists do not usually give penicillamine as a first treatment for rheumatoid arthritis since methotrexate and other DMARDs are available.
Penicillamine can be used by people with penicillin allergies. But talk to your doctor before taking any other medicines while also taking penicillamine.
How Well It Works
A recent review reports that treatment with penicillamine for about 6 months reduces rheumatoid arthritis activity and joint inflammation. But common and sometimes serious side effects limit its use.1
Penicillamine may cause birth defects and is not used during pregnancy.
Serious side effects from penicillamine include:
If you experience any of the above serious side effects, contact your doctor or seek emergency medical attention immediately.

What To Think About
Penicillamine may be more toxic than other disease-modifying antirheumatic drugs (DMARDs), such as methotrexate, and it should be used only under the supervision of a specialist in joint disease (rheumatologist) who is familiar with its side effects.
Regular blood tests are needed while taking this medicine.
