This is misleading at best. The NHS Comissioning Board has commissioned Sapropterin for use. However, due to its extraordinarily high costs and limited efficacy compared to maintaining a restricted diet, it is only prescribed in scenarios where there is an urgent clinical need for treatments like Sapropterin.
