Methoxylated Flavones and Aspirin, Hydrocodone

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Methoxylated Flavones interacts with whole categories of medication. Aspirin, Hydrocodone falls into 2 of those categories, so it can interact with Methoxylated Flavones in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Aspirin, Hydrocodone

Aspirin, Hydrocodone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Methoxylated Flavones interacts with.

In vitro evidence suggests that methoxylated flavones might inhibit cytochrome P450 3A4 (CYP3A4). This effect seems to be structure-dependent, and does not occur with all methoxylated flavones. So far this interaction has not been reported in humans. Theoretically, concurrent use of certain methoxylated flavones with drugs metabolized by CYP3A4 might result in increased drug levels and an increased risk for adverse effects.
Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), Pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline (Slo-bid, Theo-Dur, others), zileuton (Zyflo), Zolmitriptan (Zomig), and others.
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 explains PharmD, Clinical Pharmacist

Here's the gist for your aspirin and hydrocodone combo. The hydrocodone part is handled in your liver partly by an enzyme called CYP3A4. Some of these citrus-peel flavones may slow that enzyme down in lab dishes. In theory, that could let hydrocodone build up a bit, which might mean more drowsiness, dizziness, constipation, nausea, or slowed breathing if levels climbed too high.

I want to be honest though: this is based only on test-tube data, it doesn't happen with every flavone, and it has never been reported in actual people. So I wouldn't lose sleep over it. Eating an orange won't matter; concentrated supplements are the bigger question mark. Just run it by your pharmacist or doctor before adding them.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Aspirin, Hydrocodone also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

In vitro evidence suggests that some methoxylated flavones have antiplatelet effects. Theoretically, methoxylated flavones might additive effects when used with anticoagulant or antiplatelet drugs.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combination product pairs aspirin with the opioid hydrocodone, and it's the aspirin part that matters here. Aspirin already keeps your platelets from clumping, so it thins the blood a little. Methoxylated flavones from citrus peel have shown their own mild antiplatelet activity, but only in lab dishes so far. The concern is theoretical: stacking the two could in principle add up and make bleeding easier.

If that happened, you might notice things like easier bruising, nosebleeds, bleeding gums, or stomach upset (aspirin can already irritate the stomach lining). Honestly, the human evidence is thin, and ordinary amounts of citrus in food won't do this. Concentrated supplements are the real question. Before adding them, please check with your pharmacist or doctor.

From our pharmacist’s overview on the Aspirin, Hydrocodone page

“Combining supplements with aspirin and hydrocodone (Lortab ASA, Alor 5 500) deserves real vigilance, because this medication carries two separate kinds of risk. Aspirin thins the blood, and by far the largest share of these interactions can add to that effect and raise bleeding risk.”

About Methoxylated Flavones

What is Methoxylated Flavones?

  • Antioxidant support
  • Circulation and blood vessel health
  • Anti-inflammatory support
  • Skin and aging support
  • General 'metabolism' or wellness blends

Methoxylated flavones (often called polymethoxyflavones) are a group of plant compounds, found mainly in citrus peel, that include substances like nobiletin and tangeretin. Lab and animal studies suggest possible antioxidant and anti-inflammatory effects, but solid human research is very limited, so their real-world benefits are unproven. Talk with a pharmacist or doctor before using them, especially if you take medicines or are pregnant or breastfeeding.
