Adrue and Lorazepam

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Adrue interacts with whole categories of medication. Lorazepam falls into 2 of those categories, so it can interact with Adrue in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Lorazepam

Lorazepam 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 explains PharmD, Clinical Pharmacist

Here's the simple version: lorazepam (Ativan) already calms down brain activity to ease anxiety. Adrue, used traditionally as a mild calming herb, seems to do something similar. Put them together and the sedating effects can pile up. That means you might feel more drowsy, foggy, or unsteady than usual, and you could notice slower thinking or stronger sleepiness.

I want to be honest about the evidence, though. This concern comes from animal studies, not from people, where adrue made sedatives last much longer. So it's more of a theoretical, better-safe-than-sorry caution. Don't stop or change your lorazepam on your own. Just check with your pharmacist or doctor before adding adrue, and avoid driving until you know how the combination affects you.

BENZODIAZEPINES

2 of 2

Lorazepam also falls under BENZODIAZEPINES.

Animal research suggests that taking adrue in combination with diazepam increases total sleep time four-fold compared to the effects of diazepam alone. Theoretically, concomitant use adrue and benzodiazepines might increase the risk of drowsiness and motor reflex depression. Some benzodiazepines include clonazepam (Klonopin), diazepam (Valium), lorazepam (Ativan), 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: Lorazepam (Ativan) already works by calming activity in your brain, which is what eases anxiety but can also leave you drowsy. Adrue has traditionally been used as a mild calming herb, so the worry is that pairing the two could pile sedation on top of sedation. In practice that might mean feeling extra sleepy, foggy, unsteady on your feet, or having slower reflexes.

I want to be honest about the evidence, though. This concern comes from animal research (where adrue boosted a related drug's sleep time), not from human studies, so it's more of a theoretical caution than a proven problem. Still, since both can slow you down, it's worth running it by your pharmacist or doctor before combining them, especially if you drive or take other sedating medicines.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.

From our pharmacist’s overview on the Lorazepam page

“Lorazepam (Ativan) works by slowing brain activity, and that is exactly why this list deserves real caution. Of the 119 supplement and herbal ingredients on file, 78 are themselves nervous-system depressants, so adding them can deepen drowsiness or, at the extreme, slow breathing.”

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.

About Lorazepam

What Is Lorazepam Used For?

Brand name: Ativan

Lorazepam tablets (Ativan and generic) and the oral solution are used to manage anxiety disorders or for short-term relief of anxiety symptoms, including anxiety that comes with depressive symptoms. Loreev XR, an extended-release capsule, is specifically indicated for adults with anxiety disorders who are already stable on lorazepam tablets taken three times daily.

Ativan and generic lorazepam injections are used in two additional situations: treating status epilepticus (a medical emergency involving prolonged or repeated seizures) and as a pre-surgery medication in adults to produce sedation, ease anxiety, and reduce memory of events on the day of surgery.
