Supporting patients to access prescribed products

NSPKU’s advocacy and research work has identified that many people with PKU struggle to get the specialist dietary products they need.

 “Patients frequently tell me that they find it difficult to obtain prescriptions for supplies of ACBS foods and protein substitutes. Their prescriptions may be cut, reduced, interrupted or continually questioned. This can cause stress and upset to families and individuals living with PKU.”
Professor Anita MacDonald
