Dear lord no, its an antihistamine.

It's not an antihistamine. It keeps you from vomiting.

It is both. It is an antihistamine used to treat nausea. I know that sounds odd, but it is just that.

Yes. Promethazine is a Schedule V controlled substance under the Federal Controlled Substance Act. It is often combined in a syrup with codeine, and if so, then the combination is a Schedule II controlled substance. (And by the way, it is BOTH an antihistamine AND an antiemetic).

Actually phenergan alone is not a controlled substance. When combined with codeine it is a Schedule V controlled substance.

If you are a real toxicologist then please research before posting Incorrect answer, the only time Finnigan is considered a schedule five is win it is mixed with codeine and no doctor treats nausea or vomiting with codeine

Yes, I am a real forensic toxicologist, and yes you are exactly correct. Promethazine is not a controlled substance in and of itself anywhere in the USA as far as I am aware. If mixed with a low dose of codeine, the combination is a Schedule V CS under Federal law and in most states (it's the codeine that makes it so, not the promethazine). I have not posted on Drugs.com since 2010, so I don't know where the above answer came from. Apparently someone else accessed my account somehow. I would delete the erroneous answer they posted, but there doesn't seem to be any way to do that. I have changed my login credentials in an effort to prevent anyone from using my account again. Thank you for your correction, which brought this to my attention.
