Penicillamine onset may be seen in 1 to 3 months, and most responses occur within 6 months. Early adverse effects include skin rash, metallic taste, hypogeusia, stomatitis, anorexia, nausea, vomiting, and dyspepsia. Glomerulonephritis may occur, which manifests as proteinuria and hematuria. Penicillamine is usually reserved for patients who are resistant to other therapies because of the rare but potentially serious induction of autoimmune diseases (e.g., Goodpasture’s syndrome, myasthenia gravis).
