Interaction report

Sage and Hydrocodone/Chlorpheniramine

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. Hydrocodone/Chlorpheniramine 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

CNS DEPRESSANTS

1 of 4

Why this applies to Hydrocodone/Chlorpheniramine

Hydrocodone/Chlorpheniramine falls under CNS DEPRESSANTS — the group Sage interacts with.

Theoretically, taking sage might increase the sedative and adverse effects of CNS depressants.
Some constituents of sage have CNS depressant activity.
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.

Here's the gist with Tussionex (hydrocodone plus chlorpheniramine): this combo already slows you down on its own. The hydrocodone is an opioid, and chlorpheniramine is a sedating antihistamine, so together they commonly cause drowsiness, dizziness, and slowed breathing. Some compounds in sage appear to have their own mild calming activity in the body, so pairing the two could, in theory, add to that sleepy, foggy feeling.

I want to be honest about the strength of this one. It's based on lab and animal findings, not solid human studies, so it's more of a maybe than a sure thing. Cooking with sage almost certainly won't matter. Concentrated sage extracts or essential oil are where I'd be more cautious. Please run it by your pharmacist or doctor before combining them.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

2 of 4

Hydrocodone/Chlorpheniramine also falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES.

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

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's something worth knowing about Tussionex (a combination of hydrocodone and chlorpheniramine). Sage may block a liver enzyme called CYP2D6 in lab tests. With this medicine, that's a bit of a mixed bag. The hydrocodone part actually relies on CYP2D6 to turn into a stronger painkiller called hydromorphone, so blocking that enzyme could slightly weaken that effect. Meanwhile, the chlorpheniramine (the antihistamine) could build up a little, possibly leaving you extra drowsy, dry-mouthed, or foggy.

The good news: this is only a theoretical concern from test-tube studies, and it has never been reported in real people. Food amounts of sage in cooking are very unlikely to matter. If you take strong sage extracts or oils regularly, just mention it to your pharmacist or doctor.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

3 of 4

Hydrocodone/Chlorpheniramine 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

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Tussionex (hydrocodone plus chlorpheniramine) and sage. Your body uses an enzyme called CYP3A4 to help break down hydrocodone. In lab dish studies, sage extracts appeared to slow that enzyme down a little. If that happened in real life, the hydrocodone could hang around longer and hit harder, meaning more drowsiness, dizziness, constipation, or, at the extreme, slowed breathing.

That said, I don't want to overstate this. This is theoretical, based only on test-tube work, and it has never actually been reported in people. Cooking with sage in your food is not a concern. Concentrated sage capsules or oil are where I'd be more cautious. If you take those regularly, just give your pharmacist a quick heads-up.

ANTICHOLINERGIC DRUGS

4 of 4

Hydrocodone/Chlorpheniramine 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 simple version. One ingredient in Tussionex is chlorpheniramine, an antihistamine that works partly by blocking a brain chemical called acetylcholine. Lab studies suggest sage may do the opposite, raising acetylcholine levels. So in theory, sage could nudge against chlorpheniramine and slightly soften the part of this medicine that calms a cough, dries up a runny nose, and makes you sleepy.

I want to be honest about the strength here: this is only test-tube evidence, not real-world cases, so it's mostly theoretical. A little sage in your cooking is very unlikely to matter. Concentrated sage extracts or capsules are where I'd be more thoughtful. The hydrocodone part isn't really involved. If you're using sage supplements regularly, just run it by your pharmacist or doctor first.

From our pharmacist’s overview on the Hydrocodone/Chlorpheniramine page

“Tussionex (hydrocodone with chlorpheniramine) pairs an opioid with a sedating antihistamine, so anything that deepens drowsiness or slows breathing is a genuine hazard, and 78 of the 258 supplements on file do exactly that. Alcohol in any form tops that group, and kava carries a major rating for the same reason.”

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.
