A doctor gave a me a prescription for nausea because the percocet (?) I took after surgery made my head literally spin..(from the anesthesia)..I was awful...I'm copying from the bottle..It's promethazine 25mg tab mallinckro
generic equivelant for Phenergan 25mg tab
Don't know why your nausea (if pregnant, don't take this Im sure)
You can google it or call your dr. Hope this info helps..
