Cuprimine (penicillamine) is a chelating agent that helps remove copper from the body used to remove excess copper associated with Wilson's disease. Cuprimine is also used to reduce cystine in the urine and to treat severe rheumatoid arthritis. Common side effects of Cuprimine include stomach/abdominal pain, nausea, vomiting, loss of appetite, diarrhea, decreased sense of taste, itching or rash, ringing in the ears, sores in the mouth, poor wound healing, or increased wrinkling of the skin.
Dosing of Cuprimine depends on the condition being treated. Cuprimine may interact with gold-therapy products, antimalarial medicines, cancer chemotherapy medicines, phenylbutazone, digoxin, antacids, or vitamin and mineral supplements. Do not take any medicines or over-the-counter drugs or supplements within 1 hour of a Cuprimine dose. Tell your doctor all medications and supplements you use. Cuprimine is not recommended for use during pregnancy. It may harm a fetus. However, it may sometimes be used during pregnancy in certain situations (such as treating Wilson's disease); consult your doctor. It is unknown if this medication passes into breast milk. Because of the possible risk to the infant, breastfeeding while using this drug is not recommended.

Cuprimine FDA Prescribing Information: Side Effects
Penicillamine is a drug with a high incidence of untoward reactions, some of which are potentially fatal. Therefore, it is mandatory that patients receiving penicillamine therapy remain under close medical supervision throughout the period of drug administration (see WARNINGS and PRECAUTIONS).
Reported incidences (%) for the most commonly occurring adverse reactions in rheumatoid arthritis patients are noted, based on 17 representative clinical trials reported in the literature (1270 patients).
Generalized pruritus, early and late rashes (5%), pemphigus (see WARNINGS), and drug eruptions which may be accompanied by fever, arthralgia, or lymphadenopathy have occurred (see WARNINGS and PRECAUTIONS). Some patients may show a lupus erythematosus-like syndrome similar to drug-induced lupus produced by other pharmacological agents (see PRECAUTIONS).
Anorexia, epigastric pain, nausea, vomiting, or occasional diarrhea may occur (17%).
Isolated cases of reactivated peptic ulcer have occurred, as have hepatic dysfunction including hepatic failure, and pancreatitis. Intrahepatic cholestasis and toxic hepatitis have been reported rarely. There have been a few reports of increased serum alkaline phosphatase, lactic dehydrogenase, and positive cephalin flocculation and thymol turbidity tests.
Some patients may report a blunting, diminution, or total loss of taste perception (12%); or may develop oral ulcerations. Although rare, cheilosis, glossitis, and gingivostomatitis have been reported (see PRECAUTIONS).
Gastrointestinal side effects are usually reversible following cessation of therapy.
Penicillamine can cause bone marrow depression (see WARNINGS). Leukopenia (2%) and thrombocytopenia (4%) have occurred. Fatalities have been reported as a result of thrombocytopenia, agranulocytosis, aplastic anemia, and sideroblastic anemia.
Patients on penicillamine therapy may develop proteinuria (6%) and/or hematuria which, in some, may progress to the development of the nephrotic syndrome as a result of an immune complex membranous glomerulopathy (see WARNINGS). Renal failure has been reported.
Central Nervous System
Tinnitus, optic neuritis and peripheral sensory and motor neuropathies (including polyradiculoneuropathy, i.e., Guillain-Barré syndrome) have been reported. Muscular weakness may or may not occur with the peripheral neuropathies. Visual and psychic disturbances; mental disorders; and agitation and anxiety have been reported.
Adverse reactions that have been reported rarely include thrombophlebitis; hyperpyrexia (see PRECAUTIONS); falling hair or alopecia; lichen planus; polymyositis; dermatomyositis; mammary hyperplasia; elastosis perforans serpiginosa; toxic epidermal necrolysis; anetoderma (cutaneous macular atrophy); and Goodpasture's syndrome, a severe and ultimately fatal glomerulonephritis associated with intra-alveolar hemorrhage (see WARNINGS). Vasculitis, including fatal renal vasculitis, has also been reported. Allergic alveolitis, obliterative bronchiolitis, interstitial pneumonitis and pulmonary fibrosis have been reported in patients with severe rheumatoid arthritis, some of whom were receiving penicillamine. Bronchial asthma also has been reported.
The chelating action of the drug may cause increased excretion of other heavy metals such as zinc, mercury and lead.
There have been reports associating penicillamine with leukemia. However, circumstances involved in these reports are such that a cause and effect relationship to the drug has not been established.
