Bay Leaf and Benzhydrocodone, Acetaminophen

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. Benzhydrocodone, Acetaminophen 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 Benzhydrocodone, Acetaminophen

Benzhydrocodone, Acetaminophen 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.

Apadaz pairs an opioid pain reliever (benzhydrocodone) with acetaminophen. The opioid part already slows down your brain and nervous system, which is how it eases pain but also why it can make you drowsy. The concern here is simple: bay leaf contains a compound called methyl eugenol that, in animal studies, showed mild sedative effects. If you took concentrated bay leaf supplements or its essential oil alongside Apadaz, the two calming effects could add up.

What that might look like: extra sleepiness, dizziness, foggy thinking, or slowed breathing. This is theoretical and based only on lab and animal data, so it's not a strong worry. The bay leaves you use to season soup are very unlikely to matter. Just check with your pharmacist before using bay leaf supplements while on Apadaz.

NARCOTIC DRUGS

Benzhydrocodone, Acetaminophen 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 explains PharmD, Clinical Pharmacist

Here's the plain-English version for Apadaz (benzhydrocodone with acetaminophen). The concern on file is mostly a theoretical one: in large supplement-style doses, bay leaf might add to the calming, pain-relieving effects of opioids. With this medication, that could mean more drowsiness, dizziness, slowed breathing, constipation, or feeling overly sedated. There isn't solid human research behind this, so it's a caution rather than a proven problem.

The good news is that the sprinkle of bay leaf you'd use in soup or stew is very unlikely to cause any trouble. The worry only really applies to concentrated bay leaf capsules or essential oils. If you're thinking about taking those alongside Apadaz, please check with your pharmacist or doctor first before changing anything.

About Benzhydrocodone and Acetaminophen

What Is Benzhydrocodone and Acetaminophen Used For?

Brand name: Apadaz

Apadaz is indicated for the short-term management of acute pain — up to 14 days — that is severe enough to require an opioid and for which non-opioid treatments have not worked or are not expected to work. It combines benzhydrocodone (a prodrug that converts to the opioid hydrocodone) with acetaminophen.

Because of serious risks including addiction, abuse, and misuse, Apadaz is reserved for patients who have not tolerated or have not gotten adequate relief from alternative pain treatments. It should not be used for an extended period of time unless the pain remains severe enough to require an opioid and alternatives remain inadequate.
