What is Cystadane?

Cystadane works by preventing the build-up of an amino acid called homocysteine. This amino acid can harm blood vessels and contribute to heart disease, stroke, or circulation problems.

Cystadane is used to reduce homocysteine levels in people with a genetic condition called homocystinuria, in which the amino acid builds up in the body. This medicine is not a cure for homocysteinuria.

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