Research summary published · Prepared · Editorial update

The short answer

Review kava before adding it to aripiprazole lauroxil, especially if you already feel sleepy, dizzy or unsteady. The exact combination’s risk has not been quantified.

What this answer covers

Oral kava supplement with long-acting intramuscular suspension; botanical preparation and medicine route retained.

Supplement or preparation
Piper methysticum
Medication ingredient
aripiprazole lauroxil

Why alertness deserves review

Aripiprazole lauroxil has cognitive or motor impairment precautions. Kava guidance raises alertness concerns, so your symptoms and other medicines matter.

A negative driving result has limits

A small study found no driving impairment with its kava preparation compared with placebo. Oxazepam was a separate comparator, not a combined exposure with this medicine.

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

Conditional alertness review based on exact medication effects and supplement precautions; not proven pair-specific CNS depression.

Exact scope
Oral kava supplement with long-acting intramuscular suspension; botanical preparation and medicine route retained. 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: supported with conditions · 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

Population: People considering the specified supplement.

Advises against use with sedative substances. Kava may cause dizziness and has been linked to rare severe liver injury, including with different extraction methods.

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

Not a aripiprazole lauroxil study. Intrinsic liver risk does not establish added aripiprazole lauroxil hepatotoxicity; preparation and co-exposure vary.

Source 3: original human study

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

Population: Twenty-two adults in a randomized crossover driving study.

Medicinal-dose kava did not significantly impair driving outcomes; oxazepam impaired some outcomes.

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

Not combined administration or evidence that all kava preparations lack impairment.
