KUVAN 100 MG PWD FOR ORAL SUSP. 30 SACHETS

Sapropterin is used along with a restricted diet to control blood phenylalanine levels in people who have phenylketonuria (PKU; an inborn condition in which phenylalanine may build up in the blood and causes decreased intelligence and a decreased ability to focus remember and organize information). Sapropterin will only work for some people who have PKU and the only way to tell if sapropterin will help a particular patient is to give the medication for a period of time and see whether his or her phenylalanine level decreases. Sapropterin is in a class of medications called cofactors. It works by helping the body to break down phenylalanine so it will not build up in the blood.
