Ayahuasca and Zolpidem

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Zolpidem

Zolpidem 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

Your body relies on a liver enzyme called CYP3A4 to clear zolpidem out of your system. The beta-carboline compounds in ayahuasca (harmine and harmaline) may block that enzyme. If they do, zolpidem could hang around longer and build up higher than expected.

In plain terms, that means you might feel stronger sedation: extra drowsiness, dizziness, grogginess the next morning, trouble with balance, or memory gaps. I'll be honest, though, this is a theoretical concern based only on lab studies, and it hasn't actually been seen in people. On top of that, ayahuasca itself carries serious risks and is not something to mix with sleep medicine. Please check with your doctor or pharmacist before combining the two.

Ayahuasca

Ayahuasca is a powerful psychoactive brew that combines a DMT-containing plant with a vine that allows the DMT to take effect, causing intense hallucinations.

About Zolpidem

What Is Zolpidem Used For?

Brand names: Ambien CR, Intermezzo, Sublinox

Zolpidem is used short-term for insomnia. Most formulations — including Ambien, oral tablets, and Zolpidem Tartrate Capsules — are approved to help people who have trouble falling asleep at bedtime. Zolpidem Tartrate Capsules are specifically indicated for adults under 65.

The extended-release formulations (including Zolpidem Tartrate Extended-Release Tablets) help with both falling asleep and staying asleep through the night. Sublingual tablets (Edluar, Zolpidem Tartrate Sublingual Tablet, and Zolpidem tartrate sublingual) are taken as needed when you wake up in the middle of the night and cannot get back to sleep — but only if at least 4 hours of sleep time remain before you need to be up.
