Turmeric and Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Turmeric interacts with whole categories of medication. Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium falls into 3 of those categories, so it can interact with Turmeric in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

HEPATOTOXIC DRUGS

1 of 3

Why this applies to Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium

Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium 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

This combination product contains acetaminophen, which is the piece that matters here. Acetaminophen is processed by your liver, and in high doses or with heavy alcohol use it can stress the liver. Turmeric is mostly gentle, but there have been a handful of reports linking concentrated, high-dose turmeric supplements (especially the highly absorbable formulas) to liver irritation.

So the worry is simply about two things that lean on your liver at the same time. I want to be honest: this is theoretical and based on scattered case reports, not strong proof. The turmeric in your food won't be an issue. If you take turmeric capsules regularly and use this medicine often, just check with your pharmacist or doctor first, and watch for yellowing skin, dark urine, or belly pain.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Turmeric might increase or decrease levels of drugs metabolized by CYP3A4.
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4. Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib. In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition.
Conversely, other in vitro research suggests that turmeric induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. An animal model suggests that induction of CYP3A4 occurs after daily curcumin use for 1 week. However, the induction of CYP3A4 by turmeric 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

This combination product blends a few medicines, and the opium (an opioid) and chlorpheniramine (a sedating antihistamine) are the ones partly handled by a liver enzyme called CYP3A4. The concern with turmeric is that, in lab and animal studies, its curcumin can block that enzyme. If it slows the breakdown of these ingredients, levels could creep up, which might mean extra drowsiness, dizziness, constipation, slowed breathing from the opioid, or a dry mouth from the antihistamine.

Here's the honest part: this is mostly test-tube and animal evidence, and turmeric you sprinkle on food is very unlikely to cause trouble. Concentrated curcumin capsules taken daily are a different story. If you're using those, run it by your pharmacist or doctor before mixing the two.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

3 of 3

Acetaminophen, Chlorpheniramine, Phenylpropanolamine, Opium also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

Theoretically, turmeric might increase levels of drugs metabolized by CYP1A2. However, research is conflicting.
In vitro and animal research show that the turmeric constituent, curcumin, inhibits CYP1A2. However, other in vitro research suggests that curcumin does not significantly affect CYP1A2.
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

This combo product (a cold and cough mix with acetaminophen, the antihistamine chlorpheniramine, a decongestant, and a small amount of opium) contains a couple of ingredients that the liver enzyme CYP1A2 helps break down. In lab and animal studies, the curcumin in turmeric may slow that enzyme a little, which could let levels of these ingredients run higher than usual.

Honestly though, the evidence here is weak and mixed, so I wouldn't lose sleep over it. The sprinkle of turmeric on your dinner is a non-issue. If higher levels did happen, you might notice more drowsiness, dry mouth, or constipation. If you take concentrated turmeric capsules along with this medicine, just run it by your pharmacist or doctor first.

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.
