When and How to Take It

The following are some general considerations for when and how to take chlorpromazine:
  • The medication comes in tablet form. It is usually taken by mouth one to six times daily.
  • You can take it with or without food. If chlorpromazine bothers your stomach, try taking it with food.
  • Chlorpromazine should be taken at the same time(s) each day to maintain an even level in your blood.
  • For chlorpromazine to work properly, it must be taken as prescribed. The medication will not work if you stop taking it.

Dosing Information

The dose of chlorpromazine your healthcare provider recommends will vary, depending on a number of factors, including:
  • The medical condition being treated
  • Your age and weight
  • Other medical conditions you may have
  • Other medications you may be taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
