  • L-Penicillamine is a medication primarily used for the treatment of Wilson's disease. It is also used for people with kidney stones who have high urine cystine levels, rheumatoid arthritis, copper poisoning, and lead poisoning. It is taken by mouth. Common side effects include rash, loss of appetite, nausea, diarrhea, and low blood white blood cell levels. Other serious side effects include liver problems, obliterative bronchiolitis, and myasthenia gravis. It is not recommended in people with lupus erythematosus. Use during pregnancy may result in harm to the baby. Penicillamine works by binding heavy metals such that they can be removed from the body in the urine.
