Based on the information provided, it is not explicitly stated whether symptoms were completely eliminated with the use of sapropterin. However, it is mentioned that sapropterin is a medication used to reduce the frequency of migraines in patients with a specific genetic disorder [1].

Sapropterin is a prescription drug that is used to prevent migraine headaches in adults and children who have a deficiency in an enzyme called phenylalanine hydroxylase (PAH) [1]. This deficiency can lead to elevated levels of phenylalanine, an amino acid, in the blood, which can cause brain damage if left untreated [1]. Sapropterin works by helping the body break down phenylalanine, which can reduce the frequency of migraines [1].

It is important to note that while sapropterin can help reduce the frequency of migraines, it may not completely eliminate them [1]. The effectiveness of the drug can vary from person to person, and it may take some time to determine the optimal dosage [1]. Additionally, sapropterin may not be effective for all patients, and other treatments may be necessary [1].

In summary, sapropterin is a medication used to reduce the frequency of migraines in patients with a specific genetic disorder. While it may help alleviate symptoms, it may not completely eliminate them. The effectiveness of the drug can vary from person to person.
