Vitamin E and Aspirin, Hydrocodone

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

Why Are There 2 Interactions?

Vitamin E interacts with whole categories of medication. Aspirin, Hydrocodone falls into 2 of those categories, so it can interact with Vitamin E 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 Vitamin E interacts with.

Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.
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 thing to keep in mind with this combo. There's a lab-based idea that high-dose vitamin E might gently speed up an enzyme called CYP3A4, which is one of the pathways that helps process the hydrocodone part of your pill. If that happened, it could theoretically nudge your body to clear the hydrocodone a bit faster, meaning slightly less pain relief than you'd expect. This is purely theoretical, based on how things behave in the lab, not from real patient cases, so I wouldn't lose sleep over it.

One more honest note: high doses of vitamin E can thin the blood, and aspirin already does that. Together they may raise your bleeding or bruising risk. Normal food amounts of vitamin E aren't a concern. Before starting high-dose vitamin E, just check with your pharmacist or doctor.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Aspirin, Hydrocodone also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors. These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily. Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol. RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors. Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.
Severity Moderate Likelihood Possible Evidence B

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 pairs aspirin (for pain and inflammation) with hydrocodone (an opioid). The piece that matters here is the aspirin. Aspirin already thins your blood by keeping platelets from clumping together, and high-dose vitamin E does something similar. Stack the two and you can nudge your bleeding risk higher.

In real life that might look like easier bruising, nosebleeds, bleeding gums, or a cut that takes longer to stop. The research behind this is modest, and it mostly applies to large vitamin E doses (roughly 800 IU or more daily), not the small amounts in food or a basic multivitamin. The hydrocodone part isn't affected. If you're considering high-dose vitamin E, check with your pharmacist or doctor first, especially if you bleed or bruise easily.

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 Vitamin E

What is Vitamin E?

Vitamin E
  • General antioxidant support
  • Skin and hair care
  • Heart health
  • Eye health (age-related conditions)
  • Immune support

Vitamin E is an essential fat-soluble vitamin and antioxidant that most people get in adequate amounts from a normal diet. Supplements can help correct a true deficiency, but high-dose vitamin E has not been clearly proven to prevent heart disease or cancer and may carry risks. Talk to your pharmacist or doctor before taking high doses.
