What is Cuprimine?

Cuprimine is a chelating (KEE-late-ing) agent that binds to excess copper and removes it from the blood stream. In certain conditions, excess copper can build up in the blood stream, leading to tissue damage throughout the body.

Cuprimine is used to remove excess copper in people with an inherited condition called Wilson's disease.

Cuprimine is also used to reduce urine levels of an amino acid called cystine, which can cause stones to form in the kidneys and bladder in people with an inherited condition called cystinuria.

Cuprimine is also used to treat severe rheumatoid arthritis after other medicines have been tried without success. This medicine is not approved to treat juvenile rheumatoid arthritis.

Cuprimine may also be used for purposes not listed in this medication guide.
