Eucalyptus and Aripiprazole Lauroxil

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Eucalyptus interacts with.

Theoretically, eucalyptus might increase the levels of CYP3A4 substrates.
In vitro research suggests that eucalyptus oil might inhibit CYP3A4, although this has not been reported in humans.
Severity Moderate 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

Here's the gist for Aristada (aripiprazole lauroxil): your body uses a liver enzyme called CYP3A4 to help clear this medication. Lab tests in test tubes hint that eucalyptus oil might slow that enzyme down a bit. If that happened in a real person, aripiprazole could build up slightly and you might notice more of its usual side effects, things like restlessness, drowsiness, dizziness, or muscle stiffness.

The important part: this is only a theoretical concern from lab studies, and it has not been seen in actual patients. Aristada is also a long-acting shot given by your provider, so day-to-day adjustments aren't something you do yourself. Breathing in eucalyptus vapor or using a lozenge is very unlikely to matter. Still, it's worth a quick word with your doctor or pharmacist before using concentrated eucalyptus products.

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 Eucalyptus

What is Eucalyptus?

Eucalyptus
  • Cough and chest congestion
  • Colds and flu symptoms
  • Stuffy nose
  • Sore throat
  • Minor muscle and joint aches
  • Aromatherapy

Eucalyptus is best known for its strong-smelling oil used in vapor rubs, inhalants, and lozenges to ease coughs and congestion. It may provide mild, short-term relief of cold symptoms, but the oil is toxic if swallowed and must never be taken by mouth undiluted. Talk to a pharmacist or doctor before using it, especially in children, during pregnancy, or while breastfeeding.
