PATIENT MEDICATION

Promethazine

 

Description

Promethazine (also called Phenergan®) is used to treat nausea and vomiting. Promethazine is available in these forms:

  • 12.5 mg, 25 mg, and 50 mg tablets taken by mouth
  • 1.25 mg/ml and 5 mg/ml syrup (liquid) taken by mouth
  • 12.5 mg, 25 mg, and 50 mg suppositories inserted into the rectum
  • 50 mg/ml liquid given by vein

How to take and store promethazine

  • Your doctor will tell you how much promethazine to take and how often to take it.
  • Syrup and tablets
    • You may take the tablets or syrup with food or milk to avoid an upset stomach.
    • Store the tablets and syrup at room temperature. Store them away from light, heat, and moisture.
  • Rectal suppositories
    • Never take suppositories by mouth. Insert the suppository into the rectum after removing the wrapper.
    • You may wet the rectum with water to make it easier to insert the suppository. Do not apply any petroleum jelly (Vaseline®) to the rectum before you insert the suppository.
    • Place the pointed end of the suppository into the rectum, and push gently until it is all the way inside.
    • Wash your hands with soap and water after you have inserted the suppository.
    • Store the suppositories in a tightly closed container in the refrigerator.
