Ginger and Acetaminophen, Pentazocine

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Acetaminophen, Pentazocine

Acetaminophen, Pentazocine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Ginger interacts with.

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.
Severity Minor 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 situation with Talacen (which combines acetaminophen and pentazocine) and ginger. In a test tube, ginger has been shown to slow down a liver enzyme called CYP1A2. Since pentazocine is partly handled by that enzyme, the theory is that ginger could let a little more of it build up, which might mean slightly stronger effects like drowsiness, dizziness, nausea, or lightheadedness.

The important part: this has only been seen in lab studies, never in actual people. The risk is rated minor, and everyday culinary ginger in food is very unlikely to do anything here. If you're taking concentrated ginger supplements, just mention it to your pharmacist or doctor so they can keep an eye on how you feel.
