As far as I know,
Promethazine itself is not a narcotic, when
codeine or
hydrocodone is in the syrup, then it's a narcotic. The kind you have doesn't have either of those in it, though. Here's a tid bit of information on Promethazine syrup that may be useful to you. The street name for it is Sizzurp. People often mix it with Sprite and Jolly Ranchers or other like ingredients or just drink it plain to get high. In high doses it is potentially deadly (as are most drugs) and with prolonged use it often kills abusers by enlarging their heart. Even the man who coined the term Sizzurp and made abusing it to get high famous died from prolonged abuse. If it is used as directed there should be no problems. I am just telling you all of this to let you know you should keep the bottle in a place where no one can get ahold of it. I don't know how old your daughter, or any other children you may have are, but it may be tempting for someone to abuse it to get high or sell it to get money because in some places that stuff sells for a pretty penny.
