Sodium phenylbutyrate is used together with a proper diet to help treat urea cycle disorders (including a specific liver enzyme deficiency) that help remove ammonia (nitrogen) from the body.

Ammonia is formed from the breakdown of protein in the body. If the ammonia cannot be removed by the body, then a buildup may cause serious unwanted effects. This medicine works by helping to reduce high levels of ammonia in the blood.
