Trilafon is used to treat certain mental/mood disorders such as schizophrenia, manic phase of bipolar disorder, and schizoaffective disorder. Trilafon is a brand name for the antipsychotic medication perphenazine. Perphenazine belongs to a class of drugs called phenothiazines and works by helping to restore the balance of certain natural substances in the brain.
Perphenazine can help to control your symptoms but will not cure your condition. It is also used to control severe nausea and vomiting in adults. It helps you to think more clearly, feel less nervous, and take part in everyday life. It can reduce aggressive behavior and the desire to hurt yourself/others
Uses and Dosage
Perphenazine is an oral tablet that should be taken two to four times a day at around the same time each day. Follow the instructions on your prescription label carefully and ask your doctor or pharmacist if you have any questions or do not understand any part of it. Do not take more or less of it or take it more often than prescribed by your doctor.
The recommended dosage of perphenazine varies depending on the condition being treated, individual patient factors, and other medications being taken. The typical starting dose can range from 4mg to 8mg, taken orally three times a day for schizophrenia. The maximum recommended dose is 24mg in a day, but a dose reduction to the minimum effective dose as soon as possible is desirable. The optimal clinical effect or benefit may be achieved at dosages of 24mg occasionally. Elderly patients may require a lower dosage to start.
Continue taking perphenazine even if you feel well. Do not stop taking perphenazine without talking to your doctor. If you suddenly stop taking perphenazine, you may experience withdrawal symptoms such as nausea, vomiting, stomach pain, dizziness, and shakiness. Your doctor will decrease your dose gradually and may prescribe other medication(s) for you to take for several weeks after you stop taking perphenazine to avoid withdrawal symptoms.
