Does a promethazine injection interact with other drugs?

Some medications might react poorly with a promethazine injection and should be avoided until discussing the risks with your doctor. Pay careful attention to all signs of negative reactions. Medications that may interact badly with a promethazine injection include:

  • muscle relaxers
  • painkillers
  • MAO inhibitors
  • epinephrine (adrenaline)
  • blood thinners
  • drugs that make you sleepy (sleeping pills, sedatives, etc.)
  • medicines that treat high blood pressure, Parkinson's disease, depression, anxiety, ulcers, motion sickness, irritable bowel disease, urinary disorders, restless leg syndrome, pituitary gland tumors, spasms or mental illness
  • medications that treat cold and allergy symptoms

You should tell your doctor about all medicines, supplements, vitamins and herbal remedies that you take before starting on promethazine injections. Also, avoid drinking alcohol while taking promethazine, as it can worsen some of the drug's side effects.
