Research summary published · Prepared · Editorial update

The short answer

Identify this valerian root product before combining it with desipramine. The inventory name does not establish the species, and exact combination evidence is lacking.

What this answer covers

Radix et Rhizoma Valerianae species unresolved; Valeriana officinalis and Valeriana glechomifolia are not interchangeable.

Supplement or preparation
Radix et Rhizoma Valerianae
Medication ingredient
desipramine

Start with the botanical name

Ask the pharmacist to confirm the Latin species, root or rhizome, extract and other ingredients. Do not assume every valerian-root label means Valeriana officinalis.

Apply guidance only to a matching product

NCCIH advises against Valeriana officinalis with sedatives because a sleep-inducing effect is possible. That guidance is conditional on identifying the product.

The missing evidence is clinical

The available guidance does not test this root product with desipramine or establish a safe dose gap. A sleep-aid reputation alone does not prove an exact interaction.

Watch for impaired alertness

Desipramine can affect alertness and coordination. Avoid driving if affected and contact the prescriber if added sleepiness, confusion or unsteadiness appears after a new product. Severe confusion, fainting or inability to wake needs urgent assessment.

Evidence and practical considerations

Side effects & toxicity

Product identity and conditional alertness review are appropriate, but exact unidentified-root additive sedation is insufficiently established.

Exact scope
Radix et Rhizoma Valerianae species unresolved; Valeriana officinalis and Valeriana glechomifolia are not interchangeable. with Exact oral desipramine hydrochloride tablets. RxNorm IN 3247/PIN 203174 hydrochloride. Mainly norepinephrine reuptake activity does not erase the exact label’s serotonin warning. CYP2D6 inhibition can affect concentrations; not assumed identical to CYP3A substrates.
Medication form and route
oral
Timing or duration
Source-specific single-dose, repeated-dose and observational exposures distinguished.

What remains uncertain

  • No exact human co-use study identified. Animal studies of another Valeriana species cannot establish this product’s effect.

Factors that may matter: preparation and plant part; clinical indication; dose; other medicines; baseline alertness.

Research conclusion: insufficient evidence · Evidence assessment: low
