Khat and Aripiprazole Lauroxil

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

Moderate

ANTIPSYCHOTIC DRUGS

Why this applies to Aripiprazole Lauroxil

Aripiprazole Lauroxil falls under ANTIPSYCHOTIC DRUGS — the group Khat interacts with.

Khat may affect response to antipsychotic treatment. In a large retrospective study of adults with newly diagnosed schizophrenia, chewing khat was associated with a decreased retention rate with the initial antipsychotic agent when compared with non-chewers, and lack of efficacy was the most commonly reported reason for switching antipsychotic agents among khat users. Until more is known, avoid khat in patients taking antipsychotic agents.
Severity Moderate Likelihood Possible Evidence B

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 simple version: Aristada (aripiprazole lauroxil) is a long-acting shot that helps steady your thinking and mood by balancing dopamine in the brain. Khat works in almost the opposite direction, pumping up dopamine and norepinephrine like an amphetamine. In a large real-world study of people newly treated for schizophrenia, those who chewed khat were more likely to have their antipsychotic stop working well, with poor symptom control being the top reason for switching medicines.

For you, that could mean your Aristada doesn't hold your symptoms as steady, and khat itself can also stir up agitation, anxiety, high blood pressure, and racing heart. Khat is also illegal in the U.S. Please don't start or stop anything on your own, just bring this up with your doctor or pharmacist.

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.”
