Interaction report

Adrue and Clonazepam

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. Clonazepam 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 Clonazepam

Clonazepam 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 short version with adrue and your clonazepam (Klonopin). Clonazepam already calms down activity in the brain, which is how it eases seizures and panic. Adrue seems to have its own gentle calming effect. Put them together and those two relaxing actions can stack on top of each other, so you might feel more drowsy, foggy, dizzy, or unsteady than usual.

I want to be honest about how solid this is: the concern comes from animal and lab studies, not human trials, where adrue made sedative drugs work much longer. So it's a reasonable caution, not a proven danger. Still, since sleepiness and falls are real risks here, please check with your pharmacist or doctor before pairing them, and don't change your clonazepam on your own.

BENZODIAZEPINES

2 of 2

Clonazepam 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 gist with Clonazepam and adrue: clonazepam already calms the brain to ease seizures and panic attacks, and adrue is traditionally used as a mild relaxing, calming herb. Put the two together and they may pull in the same direction, meaning more sedation than you bargained for. The worry is added drowsiness, grogginess, slowed reflexes, and unsteadiness, which matters a lot if you drive or operate machinery.

I want to be honest about the evidence, though. This comes from animal research (with diazepam), where sleep time went up several-fold. We have no solid human studies, so it's a theoretical concern rather than something proven in people. Still, since both can make you sleepy, it's smart to check with your pharmacist or doctor before combining them rather than experimenting on your own.

From our pharmacist’s overview on the Clonazepam page

“Clonazepam (Klonopin) slows brain activity to control seizures and panic, and most of what interacts with it pushes in one of two directions: deepening that sedation or changing how much drug is in your blood. This is a list to approach carefully.”

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 Clonazepam

What Is Clonazepam Used For?

Brand names: Klonopin, Rivotril, Ceberclon

Clonazepam is approved to treat several types of seizures — including Lennox-Gastaut syndrome (a severe form of epilepsy), akinetic seizures (sudden loss of muscle tone), myoclonic seizures (sudden muscle jerks), and absence seizures (brief lapses of awareness) in patients who haven't responded to other medicines.

It is also approved for panic disorder, with or without agoraphobia (fear of situations that might cause panic). Panic disorder involves repeated, unexpected panic attacks along with ongoing worry about having more attacks.
