Perphenazine (Trilafon®) is a "typical antipsychotic" that is licensed to treat schizophrenia and severe nausea and vomiting. This drug is available by prescription only, and it works by blocking or lessening the effects of dopamine in the brain, which may be elevated in people with these conditions.
Prior to beginning treatment with perphenazine, information about the drug's precautions and warnings should be reviewed with your healthcare provider. This includes knowing the side effects to watch out for, such as drowsiness and dry mouth, and how to properly store this product. In addition, tell your healthcare provider if you have any allergies or any other medical conditions, such as glaucoma or kidney disease.
