This medicine works by causing less ammonia to be produced by 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. In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
