Lavender and Aripiprazole Lauroxil

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CNS DEPRESSANTS

Why this applies to Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under CNS DEPRESSANTS — the group Lavender interacts with.

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.
Laboratory research suggests that lavender has sedative effects. However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness. There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.
Severity Moderate Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Aristada (aripiprazole lauroxil): both lavender and this long-acting antipsychotic can have a calming effect on the brain. The theory is that pairing them could add up, so you might feel a bit more drowsy, sleepy, or mentally foggy than usual. Since aripiprazole is given as a long-acting shot, that sedating effect tends to be steady over weeks.

The good news is that this is only a theoretical concern based on how lavender behaves in lab studies. In real people, oral lavender (like Silexan 160 mg) hasn't reliably caused drowsiness. Food or aromatherapy amounts are very unlikely to matter. Still, if you start a concentrated oral lavender supplement, mention it to your pharmacist or doctor first, and don't change your injection on your own.

From our pharmacist’s overview on the Aripiprazole Lauroxil page

“Aripiprazole lauroxil (Aristada) is a long-acting antipsychotic injection, and because each dose keeps working for weeks, a bad supplement pairing cannot be undone by skipping a pill. So the 16 major-rated entries among its 233 interactions on file deserve to be understood first.”

About Lavender

What is Lavender?

Lavender
  • Anxiety and stress
  • Sleep problems

  • Minor skin conditions
  • Aromatherapy

Lavender is a fragrant herb most popular for promoting relaxation, easing anxiety, and supporting sleep, with some encouraging evidence for a standardized oral lavender oil product for anxiety. While generally well tolerated, the essential oil should never be swallowed unless made for that purpose, and pregnant or breastfeeding people should use caution and talk to a healthcare provider first.
