Potential Negative Interaction

  • Henbane

    Antihistamines, including brompheniramine, can cause “anticholinergic” side effects such as dryness of mouth and heart palpitations. Henbane (Hyoscyamus niger) also has anticholinergic activity and side effects. Therefore, use with brompheniramine could increase the risk of anticholinergic side effects,1 though apparently no interactions have yet been reported with brompheniramine and henbane. Henbane should not be taken except by prescription from a physician trained in its use, as it is extremely toxic.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Explanation Required

If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
