Sage and Acetaminophen, Chlorpheniramine, Dextromethorphan

These two interact in 4 distinct ways. Each one is explained separately below.

Why Are There 4 Interactions?

Sage interacts with whole categories of medication. Acetaminophen, Chlorpheniramine, Dextromethorphan falls into 4 of those categories, so it can interact with Sage in 4 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

1 of 4

Why this applies to Acetaminophen, Chlorpheniramine, Dextromethorphan

Acetaminophen, Chlorpheniramine, Dextromethorphan falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Sage interacts with.

Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP2D6.
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP2D6. So far, this interaction 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

In this combo product, the ingredient to watch is the dextromethorphan (the cough suppressant). Your liver uses an enzyme called CYP2D6 to clear it out. Lab studies hint that sage may slow that enzyme down a bit, so in theory dextromethorphan could build up and hit you harder than usual. That might mean more drowsiness, dizziness, or feeling foggy, and the chlorpheniramine (an antihistamine) can already make you sleepy on its own.

Here's the reassuring part: this is only seen in test-tube research, never reported in real people, and a sprinkle of sage in cooking is very unlikely to matter. Concentrated sage extracts or oils would be the bigger question. If you take those regularly, just run it by your pharmacist or doctor first.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 4

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

Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP3A4. So far, this interaction 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

Here's the gist with this combo cold product (the Coricidin II type with acetaminophen, chlorpheniramine, and dextromethorphan). Sage has shown, in lab dish studies only, that it can slow down a liver enzyme called CYP3A4. The dextromethorphan piece leans on that enzyme to be cleared. So in theory, sage could let it build up a bit, which might mean more drowsiness, dizziness, or feeling foggy than usual.

I want to be honest though: this has only been seen in test tubes, never reported in real people, so the concern is low. A pinch of sage in cooking is no worry at all. Concentrated sage extracts or the essential oil are where I'd be more cautious. If you use those regularly, just run it by your pharmacist or doctor first.

ANTICHOLINERGIC DRUGS

3 of 4

Acetaminophen, Chlorpheniramine, Dextromethorphan also falls under ANTICHOLINERGIC DRUGS.

Theoretically, sage might decrease the clinical effects of anticholinergic drugs.
In vitro evidence suggests that common sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) can inhibit acetylcholinesterase and might increase acetylcholine levels.
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 piece that matters for this product: the chlorpheniramine in Coricidin II is an antihistamine with anticholinergic activity, meaning it works partly by lowering the action of a brain chemical called acetylcholine. In lab studies, sage appears to do the opposite by raising acetylcholine levels. So in theory, taking concentrated sage could blunt some of chlorpheniramine's effects, like the drowsiness or dry mouth it usually causes. The acetaminophen and dextromethorphan parts aren't really involved here.

I want to be honest: this is theoretical and based only on test-tube research, not real people. A bit of sage in your cooking won't matter. If you regularly use strong sage extracts or oils, just mention it to your pharmacist so they can keep an eye on things.

CYTOCHROME P450 2E1 (CYP2E1) SUBSTRATES

4 of 4

Acetaminophen, Chlorpheniramine, Dextromethorphan also falls under CYTOCHROME P450 2E1 (CYP2E1) SUBSTRATES.

Theoretically, sage might decrease the levels and clinical effects of drugs metabolized by CYP2E1.
Animal research suggests that drinking common sage (Salvia officinalis) tea increases the expression of CYP2E1. So far, this interaction has not been reported in humans.

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 piece of this combo product that matters most: the acetaminophen (Tylenol) portion is partly handled by a liver enzyme called CYP2E1. In animal studies, sage tea seemed to rev that enzyme up a bit. If that held true in people, it could shift how acetaminophen is broken down, and one concern with CYP2E1 is that it produces a small amount of a toxic byproduct, which matters most at high acetaminophen doses or with regular alcohol use.

That said, this is purely theoretical and based only on lab and animal work, with nothing reported in humans. A little sage in cooking is not a worry. If you regularly take concentrated sage extracts or oil, just mention it to your pharmacist, and never exceed the labeled acetaminophen dose.

From our pharmacist’s overview on the Acetaminophen, Chlorpheniramine, Dextromethorphan page

“Alcohol is the risk to understand first. It carries major ratings alongside the acetaminophen, chlorpheniramine, and dextromethorphan combination sold as Coricidin II Extra Strength Cold and Flu, because acetaminophen already taxes the liver, and heavy drinking on top of it raises the chance of genuine liver injury.”

About Sage

What is Sage?

Sage
  • Sore throat and mouth irritation
  • Digestive upset
  • Excessive sweating
  • Memory and thinking
  • Menopause symptoms (hot flashes)
  • General antioxidant support

Sage is a common kitchen herb that is generally safe in food amounts and is traditionally used for sore throats, digestion, sweating, and memory. Some early research is encouraging for sore throat and menopausal hot flashes, but most uses are not well proven. Concentrated extracts and the essential oil should be used carefully because high doses contain a compound called thujone, which can be harmful.
