Trilafon / Perphenan (perphenazine) is a typical antipsychotic drug that can be prescribed to treat schizophrenia and other psychotic conditions, such as the manic phase of bipolar disorder. It can also be used to control severe nausea and vomiting in adults. Perphenazine works to balance the levels of dopamine in the brain. Dopamine regulates mood, behaviors, and thoughts. Schizophrenia is a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate behavior and emotions. While there is no cure for schizophrenia, many patients being treated with antipsychotic drugs like Trilafon with do better, showing minimal symptoms most of the time. Antipsychotic medications help reduce the chances of future episodes, and reduce their severity in the acute phase of the illness. Trilafon is used to manage severe nausea and vomiting, especially for post-operative patients above the age of 14.
