Information for US patients



In addition to the phenylalanine-restricted diet, some patients with PKU also take a medication called sapropterin dihydrochloride, the active ingredient in JAVYGTOR. This medication helps the PAH enzyme work more effectively to break down phenylalanine in the body.1

JAVYGTOR is the same proven sapropterin dihydrochloride you may have taken previously and is available as tablets or powder for oral solution.1 Always take JAVGTOR as your doctor has prescribed it.

JAVYGTOR is not a cure for PKU, but when combined with a phenylalanine-restricted diet it can help keep phenylalanine levels under control,1 and may help you manage your condition with confidence.
