Turmeric and Propoxyphene

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Propoxyphene

Propoxyphene falls under HEPATOTOXIC DRUGS — the group Turmeric interacts with.

Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
There is concern that turmeric might cause hepatotoxicity, especially when highly bioavailable formulations are used in high doses.
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 with turmeric and propoxyphene: both of these can put some stress on your liver. Propoxyphene is a pain reliever that your liver has to process, and on rare occasions it has been linked to liver irritation. Concentrated turmeric supplements, especially the high-dose, 'highly absorbable' formulas, have also been tied to liver problems in a handful of reports. Stack them together and the theory is that the combined burden on your liver could go up a bit.

I want to be honest about how strong this is: it's mostly theoretical and based on scattered case reports, not solid studies. The turmeric you sprinkle on food is very unlikely to matter. Still, before adding a concentrated supplement, run it past your pharmacist or doctor first.

See Every Supplement That Interacts With Propoxyphene

This page covers Turmeric only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Propoxyphene page lists 172 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 · 141 moderate · 23 minor.

From our pharmacist’s overview on the Propoxyphene page

“Propoxyphene (Darvon) is an opioid painkiller, and the biggest hazard among the 172 supplement interactions on file is anything else that slows the brain and breathing. Seventy-eight of these ingredients pile on that sedation, alcohol and kava among the worst rated, and with an opioid the combination can push breathing dangerously low.”

About Turmeric

What is Turmeric?

Turmeric
  • Joint pain and arthritis
  • Inflammation
  • Digestive upset
  • Antioxidant support
  • Skin conditions

Turmeric is a popular spice whose main active compounds, curcuminoids, are studied mostly for inflammation and joint pain. Some research is promising, but quality is mixed and curcumin is poorly absorbed on its own. For most people, dietary amounts are safe, but talk to your pharmacist or doctor before taking concentrated supplements, especially if you are pregnant, nursing, or have a medical condition.

About Acetaminophen, Butalbital, and Caffeine

What Is Acetaminophen, Butalbital, and Caffeine Used For?

Brand names: Darvon, Prophene-65, Margesic, Davon

This three-ingredient combination — butalbital, acetaminophen, and caffeine — is used to relieve the symptoms of tension headache (also called muscle contraction headache). All supported products, including tablets, capsules, and oral solution, share this same approved use.

It is worth knowing that evidence for using this combination to treat repeated, frequent tension headaches over time is limited. Because butalbital can be habit-forming, extended or repeated use is not recommended.
