Ayahuasca and Alprazolam

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Alprazolam

Alprazolam falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Ayahuasca interacts with.

Theoretically, ayahuasca might increase plasma concentrations of CYP3A4 substrates.
Ayahuasca contains beta-carboline alkaloids. In vitro research suggests that beta-carboline alkaloids competitively inhibit CYP3A4 enzymes. This effect 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 basic idea. Your body relies on a liver enzyme called CYP3A4 to clear alprazolam (Xanax) out of your system. The beta-carboline alkaloids in ayahuasca may slow that enzyme down. In a lab setting, they appear to block CYP3A4, which in theory could let more alprazolam build up in your blood than usual.

If that happened, you might feel the drug more strongly: extra drowsiness, dizziness, foggy thinking, poor coordination, or slowed breathing. I want to be honest though, this is based only on test-tube research and has not been confirmed in people. On top of that, ayahuasca itself is risky and can cause dangerous reactions. Please don't combine these without talking to your doctor or pharmacist first.

From our pharmacist’s overview on the Alprazolam page

“Sedation stacking is the core danger with alprazolam (Xanax), a benzodiazepine for anxiety and panic, and this list deserves genuine care rather than a quick skim. Dozens of entries, alcohol chief among them, deepen its drowsiness and can slow breathing, while an even larger group changes how the body clears the drug through the CYP3A4…”

About Alprazolam

What Is Alprazolam Used For?

Brand names: Xanax, Niravam

Alprazolam treats generalized anxiety disorder (GAD) and panic disorder, with or without agoraphobia, in adults. These uses are supported across multiple alprazolam products, including tablets, orally disintegrating tablets, oral solution, and extended-release tablets.

Xanax (tablet) is indicated for the acute treatment of GAD and for panic disorder. Xanax XR (extended-release tablet) and alprazolam extended-release tablets are indicated specifically for panic disorder with or without agoraphobia — not for GAD. Alprazolam orally disintegrating tablets and alprazolam oral solution are indicated for both GAD and panic disorder.
