Premedication

For EPIC users, please direct providers to Order Set "Contrast Allergy Pre Treatment"


PREMEDICATION FOR CONTRAST REACTION 

ORAL REGIMEN (Preferred to IV premedication, unless immediately urgent):

- 50 mg PO Prednisone (13, 7, and 1 hour (s) prior to contrast administration) AND 50 mg PO Diphenyhydramine (Benadryl®) 1 hour prior
- 32 mg PO Methylprednisolone 12 and 2 hours prior to contrast administration AND 50 mg PO Diphenyhydramine 1 hour prior

INTRAVENOUS PREMEDICATION (Emergency):

- 200 mg of IV Hydrocortisone (Q4H until scan, ideally 2 doses) AND 50 mg IV Diphenhydramine 1 hour prior

NOTES:
- Steroids must be given 4 -6 hours pre contrast to be effective

- Pre-medication may help reduce, but not fully eliminate, the risk of a serious contrast reaction in a patient considered to be at elevated risk. It mostly reduces chance of minor risks.
