Bay Leaf and Oxycodone

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Bay Leaf interacts with whole categories of medication. Oxycodone falls into 2 of those categories, so it can interact with Bay Leaf in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Oxycodone

Oxycodone falls under CNS DEPRESSANTS — the group Bay Leaf interacts with.

Theoretically, taking bay leaf in large amounts may enhance the therapeutic and adverse effects of sedatives.
Bay leaf contains methyl eugenol. Animal research shows that methyl eugenol has sedative properties. Avoid concomitant use.
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 explains PharmD, Clinical Pharmacist

Here's the gist for oxycodone: this is a strong opioid pain reliever that already slows down your brain and body, causing drowsiness, slowed breathing, and that foggy, sedated feeling. Bay leaf contains a compound called methyl eugenol, which in animal studies seems to have its own mild calming, sedative effect. So the worry is that stacking the two could add together and make you more sleepy or sluggish than oxycodone alone.

Now, the good news: this is theoretical and based on animal data, not strong human evidence. The bay leaf you toss into soup or sauce is very unlikely to matter at all. The caution really applies to concentrated bay leaf supplements or essential oils. If you're considering those while on oxycodone, please run it by your pharmacist or doctor first.

NARCOTIC DRUGS

2 of 2

Oxycodone also falls under NARCOTIC DRUGS.

Theoretically, taking bay leaf in large amounts may enhance the therapeutic and adverse effects of narcotics. Avoid concomitant use.
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 bay leaf and oxycodone: this is a theoretical concern, based on how things look on paper rather than solid human studies. The idea is that taking bay leaf in concentrated amounts (think supplements or essential oils, not the leaf you toss into a pot of soup) could add to the calming, sedating effects of an opioid like oxycodone.

If that played out, you might notice more drowsiness, dizziness, slower breathing, constipation, or feeling foggy. Because those effects can stack, it's worth a heads-up, but I don't want to alarm you, the evidence here is weak. The pinch of bay leaf in your cooking is very unlikely to matter. If you're thinking about a bay leaf supplement while on oxycodone, please run it by your pharmacist or doctor first.

  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

See Every Supplement That Interacts With Oxycodone

This page covers Bay Leaf only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Oxycodone page lists 145 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 8 major · 114 moderate · 23 minor.

From our pharmacist’s overview on the Oxycodone page

“Oxycodone is a potent opioid painkiller, and anything that deepens its sedation can slow breathing itself, which is why this list deserves genuine respect. Of the 145 supplement and herbal ingredients on record, eight rate major, and the biggest cluster by far, 78 ingredients, adds extra drowsiness on top of the opioid's own.”

About Oxycodone

What Is Oxycodone Used For?

Brand names: OxyContin, Roxicodone, OxyIR, Percolone, Oxecta, OxyNeo

Oxycodone treats pain that is severe enough to need an opioid pain medicine, when other treatments are not enough. Other options include non-opioid pain relievers or opioid combination products.

Some products are for specific situations. Extended-release products (OxyContin, Xtampza ER, and oxycodone extended-release tablets) are for severe, persistent pain that needs daily, around-the-clock treatment. They are not for as-needed use. The 100 mg per 5 mL (20 mg/mL) oral solution is only for opioid-tolerant patients. Oxaydo is labeled for acute and chronic pain.
