Research summary published · Prepared · Editorial update

The short answer

Confirm the species in this valerian-root product before using it with aripiprazole lauroxil. Its inventory name does not establish which evidence applies.

What this answer covers

Radix et Rhizoma Valerianae: exact species and preparation unresolved; V. officinalis findings apply only after identity confirmation.

Supplement or preparation
Radix et Rhizoma Valerianae
Medication ingredient
aripiprazole lauroxil

Confirm the root identity

Ask the pharmacist to verify the Latin species, root or rhizome, extract and other ingredients. A generic valerian-root name is insufficient to establish Valeriana officinalis.

A metabolic study is not a sedation trial

A valerian study using alprazolam as an enzyme probe did not establish a large metabolic interaction. It cannot determine alertness effects with aripiprazole lauroxil or show that every valerian extract behaves alike.

Identify the complete product

Bring the amount, preparation and other ingredients to the pharmacist. These sources do not provide a universal safe dose or a protective gap between the supplement and medicine.

Watch for impaired alertness

Aripiprazole lauroxil 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

Exact unidentified-root interaction remains insufficiently established; product confirmation and conditional alertness review are appropriate.

Exact scope
Radix et Rhizoma Valerianae: exact species and preparation unresolved; V. officinalis findings apply only after identity confirmation. with Exact aripiprazole lauroxil long-acting intramuscular suspension. Exact RxNorm IN1673265, ester prodrug, not oral aripiprazole. ARISTADA maintenance injection and ARISTADA INITIO initiation product distinguished; oral aripiprazole clinical findings require explicit active-metabolite bridge.
Medication form and route
intramuscular
Timing or duration
Source-specific single-dose, repeated-dose and observational exposures distinguished.

What remains uncertain

  • No exact-pair co-use trial identified; standalone or other-medicine findings and product differences prevent a uniform risk estimate.

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

Research conclusion: insufficient evidence · Evidence assessment: low

Source 1: current product label

dailymed.nlm.nih.gov · Source check Sep 10, 2026

Population: People prescribed aripiprazole lauroxil.

Prodrug hydrolyzed to active aripiprazole; long-acting injection, cognitive/motor and orthostatic precautions; duration-dependent CYP3A4 inducer instructions.

How this applies: Exact RxNorm IN1673265, ester prodrug, not oral aripiprazole. ARISTADA maintenance injection and ARISTADA INITIO initiation product distinguished; oral aripiprazole clinical findings require explicit active-metabolite bridge.

No supplement-specific event rate, universal timing rule or untested route/preparation equivalence.

Source 2: official guidance

nccih.nih.gov · Source check Sep 10, 2026

Population: People considering the specified supplement.

Possible but unproven sleep-inducing effect; advises against use with alcohol or sedatives. Mental dullness can occur; long-term safety is uncertain.

How this applies: Preparation-specific evidence; exact aripiprazole lauroxil co-use is not inferred from another medicine or route.

No aripiprazole lauroxil interaction trial. Chronic use can be followed by withdrawal symptoms when stopped abruptly.

Source 3: original human study

pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026

Population: Twelve healthy volunteers.

Alprazolam peak concentration increased modestly, but AUC and elimination half-life did not change significantly.

How this applies: Preparation-specific evidence; exact aripiprazole lauroxil co-use is not inferred from another medicine or route.

PK study is not a clinical sedation safety trial. Exact extract/species cannot resolve an unidentified valerian-root inventory item.
