Hello, my 14 year old daughter has just recently been diagnosed with chronic function abdominal pain. She is experiencing some mild nausea and stomach cramping right now. I want to give her something to get it under control before it graduates to the vomiting. She has been prescribed promethazine suppositories, which we have never used before. I gave her 2 pepto bismol pills, 2 1/2 tsp liquid Benadryl and her omeprazole. She also takes zyprexa at night. My question is; can we use thepromethazine suppositories and Tylenol along with these other meds or do they need to be spaced out?
