nausea/vomiting
"By far the best anti nausea medication. I've had Zofran, Hydroxyzine, and some over the counter stuff, nothing compares to Promethazine. It takes about 30-60 minutes to fully peak, once it does.. It works wonders. Zofran is good for on the spot nausea, to work fast. But if you have chronic nausea, Promethazine works both ways!"
