For those who are being treated for schizophrenia with prochlorperazine, dosing typically starts at 5 mg or 10 mg three or four times a day. For the treatment of nausea or vomiting, the recommended starting prochlorperazine dose is also 5 mg to 10 mg three or four times daily (or one 25 mg rectal suppository twice a day). The suggested prochlorperazine dosage for anxiety treatment is 5 mg three or four times daily.
The dose of prochlorperazine maleate (Compazine®) that your healthcare provider recommends will vary depending on a number of factors, including:
- The medical condition being treated
- Your age and weight (for children)
- The form of prochlorperazine (tablet, suppository, or injection)
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your prochlorperazine dosage unless your healthcare provider specifically instructs you to do so.
