What Is Phenylketonuria?
10. What Other Treatment Options Are There?
Adults with PKU may have an additional treatment option. There is a supplement called neutral amino acid therapy, available in both powder and tablet forms, that may reduce the absorption of phenylalanine into the blood. This option is not necessarily the right choice for everyone, but those who are interested should discuss the possibility with their physician.
A relatively new drug, saproterin, has been approved by the FDA. This medication has the potential to increase phenylalanine tolerance for some people. Future scientific studies are needed to determine long-term efficacy and safety.
