The use of steroids (e.g., Decadron 4 mg IV, along with other antiemetics) is being used post anesthesia to help control nausea.
Chlorpromazine IM dosing is 25 mg IM for the initial dose. If no hypotension occurs, the dose is 25 to 50 mg IM every 3 to 4 hours as needed until the vomiting stops. Then switch to oral dosage.
Promethazine topical is not commercially available but is a compounded product. It can be made in varying doses but it seems that the most common dose is 50 mg/ml of Promethazine in Pluronic Lecithin Organogel (PLO) and it is applied to the ventral surface of the non-dominant wrist and then covered with a dressing. The beyond use date is 14 days from preparation.
