Adrue and Chlorpromazine

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Chlorpromazine

Chlorpromazine falls under CNS DEPRESSANTS — the group Adrue interacts with.

Animal research suggests that taking adrue in combination with sodium thiopental or diazepam increases total sleep time up to four-fold compared to the effects of the drugs alone. Theoretically, concomitant use of adrue with CNS depressants might cause additive sedation. Some CNS depressants include benzodiazepines, such as diazepam (Valium), alprazolam (Xanax), triazolam (Halcion), and estazolam (ProSom); barbiturates, such as mephobarbital (Mebaral), phenobarbital (Luminal Sodium), and pentobarbital sodium (Nembutal); zolpidem (Ambien); and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: chlorpromazine already tends to make people drowsy and relaxed, and adrue has traditionally been used as a calming, sedating herb. Put the two together and that sleepy effect could stack up. You might notice more grogginess, deeper drowsiness, dizziness, or feeling unsteady on your feet, which can raise the risk of falls, especially in older folks.

I want to be honest about how strong this warning is, though. The concern comes from animal and lab studies only, where adrue lengthened sleep time from sedative drugs. We don't have solid human data, so this is more of a theoretical caution than a proven problem. Chlorpromazine isn't a prodrug, so the worry here is simply added sedation, not a change in how the drug is activated. Please run it by your pharmacist or doctor before combining them.

About Adrue

What is Adrue?

Adrue
  • Nausea and vomiting
  • Digestive upset, gas, and diarrhea
  • Calming or sedative effect
  • Traditional use for fevers and infections

Adrue (Cyperus articulatus) is a sedge whose rhizome has long been used in traditional medicine for nausea and other stomach complaints, and as a mild calming agent. Solid human studies are lacking, so its real benefits and safe doses are not well established. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.
