Adrue and Amitriptyline, Chlordiazepoxide

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. Amitriptyline, Chlordiazepoxide 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 Amitriptyline, Chlordiazepoxide

Amitriptyline, Chlordiazepoxide 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.

Here's the thing to keep in mind with Limbitrol DS: it's already a two-in-one sedating medicine. Amitriptyline is a tricyclic antidepressant that tends to make people drowsy, and chlordiazepoxide is a benzodiazepine, the same family as Valium. Both of these calm the central nervous system on their own.

Adrue may have its own mild calming effect. The concern here is simply stacking sedation on top of sedation, which could leave you more drowsy, foggy, dizzy, or unsteady than usual. I'll be honest though: this is based mostly on animal and lab research, not solid human studies, so it's more of a theoretical caution than a proven problem. Still, since both drugs already cause sleepiness, it's worth running it past your pharmacist or doctor before combining them.

BENZODIAZEPINES

2 of 2

Amitriptyline, Chlordiazepoxide 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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Limbitrol DS is a combination pill that pairs amitriptyline (an older antidepressant) with chlordiazepoxide (a benzodiazepine in the same family as Valium). Both of these are already sedating on their own. The concern with Adrue is mostly about adding more calm on top of calm. In animal studies, Adrue roughly quadrupled the sleep time produced by diazepam, so combining it with this medicine could, in theory, deepen the drowsiness, slow your reflexes, and leave you feeling groggy, foggy, or unsteady on your feet.

To be honest, this is based only on lab and animal work, not human trials, so it is a theoretical caution rather than a proven problem. Still, because both halves of Limbitrol DS already make people sleepy, it's worth a quick chat with your pharmacist or doctor before mixing in Adrue.

From our pharmacist’s overview on the Amitriptyline, Chlordiazepoxide page

“Alcohol is the first thing to know about here. Beer and wine both carry major, well-documented interactions with Amitriptyline and Chlordiazepoxide (Limbitrol DS), because both drugs already slow the central nervous system, and anything sedating layered on top can deepen ordinary drowsiness into something dangerous.”

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.
