Promethazine Interactions with Herbs
Henbane (Hyoscyamus niger)
Antihistamines, including promethazine, can cause “anticholinergic” side effects
such as dryness of mouth and heart palpitations. Henbane also has anticholinergic activity and
side effects. Therefore, use with promethazine could increase the risk of anticholinergic side
effects,1 though apparently no interactions have yet been reported with
promethazine and henbane. Henbane should not be taken except by prescription from a physician
trained in its use, as it is extremely toxic.
Promethazine Interactions with Foods and Other Compounds
Alcohol
causes drowsiness.2 Alcohol may intensify this effect and increase the
risk of accidental injury.3 To prevent problems, people taking promethazine or
promethazine-containing products should avoid alcohol.
