Summary
Perphenazine is used to treat schizophrenia, which is a mental disorder affecting thoughts, feelings, and behavior. It helps manage symptoms like hallucinations, which are seeing or hearing things that aren't there, and delusions, which are false beliefs. It can also control severe nausea and vomiting.
Perphenazine works by affecting chemicals in the brain called neurotransmitters, which help regulate mood and behavior. It blocks dopamine receptors, which reduces symptoms like hallucinations and delusions. This helps improve mental health symptoms by balancing these chemicals.
The usual starting dose for adults is 4 to 8 mg taken two to three times a day. The maximum recommended dose is 64 mg per day. It's taken orally, which means by mouth, and the dose can be adjusted based on individual response and needs.
Common side effects of Perphenazine include drowsiness, which is feeling sleepy, dry mouth, which is a lack of saliva, and blurred vision, which is unclear sight. These effects can vary in frequency and severity, and not everyone will experience them.
Perphenazine can increase the risk of tardive dyskinesia, which is a serious movement disorder, and neuroleptic malignant syndrome, which is a life-threatening condition. It's not recommended for people with severe central nervous system depression, which is reduced brain activity, or known allergies to the drug.
