If you take medications for Wilson's disease, treatment is lifelong. Medications include:
Penicillamine (Cuprimine, Depen). A chelating agent, penicillamine can cause serious side effects, including skin and kidney problems, bone marrow suppression, and worsening of neurological symptoms. Penicillamine should be used cautiously if you have a penicillin allergy. It also keeps vitamin B-6 (pyridoxine) from working, so you'll need to take a supplement in small doses.
Trientine (Syprine). Trientine works much like penicillamine but tends to cause fewer side effects. Still, neurological symptoms can worsen when taking trientine.
Zinc acetate (Galzin). This medication prevents your body from absorbing copper from the food you eat. It is typically used as maintenance therapy to prevent copper from building up again after treatment with penicillamine or trientine.
Zinc acetate might be used as primary therapy if you can't take penicillamine or trientine. Zinc acetate can cause stomach upset.
