An Introduction to Perphenazine Dosing
The dose of perphenazine
) that your healthcare provider recommends will vary, depending on a number of factors, including:
- The medical condition being treated
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your perphenazine dose unless your healthcare provider specifically instructs you to do so.
Perphenazine Dosing for Schizophrenia
The recommended starting dose of perphenazine for schizophrenia
is perphenazine 4 mg to 8 mg three times daily (although people under medical supervision in a hospital may start at higher dosages). Ideally, your healthcare provider will quickly lower your dose once your symptoms are under control.
Perphenazine Dosing for Nausea and Vomiting
The recommended dose of perphenazine for severe nausea and vomiting is perphenazine 8 mg to 16 mg per day (split up into two or more smaller doses). Some people may need a higher dose to control their nausea and vomiting initially (up to 24 mg per day), but the dose should quickly be reduced if possible.
