Rhodiola and Chlordiazepoxide, Clidinium Bromide

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

Why Are There 2 Interactions?

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Chlordiazepoxide, Clidinium Bromide

Chlordiazepoxide, Clidinium Bromide falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Rhodiola interacts with.

Theoretically, rhodiola might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that rhodiola inhibits CYP1A2. This effect is highly variable and appears to be dependent on the rhodiola product studied. However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of caffeine, a CYP1A2 substrate.
Severity Minor Likelihood Possible Evidence B

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 gist with Librax (chlordiazepoxide plus clidinium) and rhodiola. In lab studies, rhodiola can slow down a liver enzyme called CYP1A2, which helps clear the chlordiazepoxide piece of this combo. In theory, blocking that enzyme could let levels creep up a bit, which might mean more drowsiness, dizziness, grogginess, or trouble concentrating.

That said, I wouldn't lose sleep over it. The evidence is weak and mostly test-tube based, and a human study found rhodiola did not actually slow another CYP1A2 drug. The effect also varies a lot by product. Still, since both can make you sleepy, it's smart to mention rhodiola to your pharmacist or doctor before combining them, and don't change anything on your own.

CNS DEPRESSANTS

2 of 2

Chlordiazepoxide, Clidinium Bromide also falls under CNS DEPRESSANTS.

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.
Severity Minor 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

The chlordiazepoxide part of Librax is a benzodiazepine, which already calms the brain and can cause drowsiness, dizziness, and slowed thinking. The concern here is simple overlap: Rhodiola may add a mild extra layer of sedation on top of a medicine that already relaxes the nervous system. The worry isn't that Rhodiola changes how your body breaks the drug down, but that the two together could leave you more sleepy or foggy than expected.

To be honest, this is a theoretical caution built on a handful of anecdotal reports, not strong proof, and it's rated minor. Still, since everyone reacts differently, please run it by your pharmacist or doctor before adding Rhodiola, and don't drive until you know how the combo affects you.
