What are the dangers of a promethazine/codeine mixture?
Q: I recently got some prescription promethazine/codeine syrup from my doctor. I'm worried about drinking more than the 10mL dose though because of the promethazine which I have no idea what it is. What is promethazine? Would it harm me if I drank more?

A: Promethazine is an anti-histamine. While it is also listed as an anti-emetic (prevents nausea/vomiting), I would be concerned that higher levels may cause dizziness and nausea. Certainly in conjunction with another central nervous system depressant (the codeine) it may cause excessive sleepiness. In other words, it may knock you out or make you feel ill before you have any fun. Many medical preparations contain ingredients (such as guaifenesin) which cause nausea and vomiting at high doses. These preparations are intended to make it harder to use these drugs for fun and to keep people from accidentally overdosing.
