    Buphenyl is used along with diet changes for long-term treatment of a certain inherited disorder (urea cycle disorder). It helps remove a certain chemical (ammonia) from the body. Too much ammonia in the body can cause brain damage and sometimes death. Buphenyl should not be used to treat sudden, severely high levels of ammonia in the body. Get medical help right away if you have sudden symptoms of too much ammonia, such as trouble thinking, vomiting, irritability, trouble speaking, trouble walking, fainting.
