No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Tocotrienols and Everolimus in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Tocotrienols and Everolimus

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Everolimus and Tocotrienols in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Tocotrienols safety at a glance

Tocotrienols overall Use caution Generally well tolerated in studies, but long-term safety at supplement doses is not well established.
Pregnancy Avoid Not enough safety information, so it is best to avoid supplemental doses during pregnancy.
Breastfeeding Use caution Little is known about safety while breastfeeding, so avoid supplements unless advised by your doctor.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Everolimus

Interactions in our licensed database are recorded against drug classes, not just single drug names. Everolimus is filed under 7 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, cytochrome p450 3a4 (cyp3a4) inhibitors, p-glycoprotein substrates. Tocotrienols has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (minor) — and none of Everolimus’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Tocotrienols and Everolimus May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Itching Additional detail

    Tocotrienols

    “Topically, a cream containing 5% tocotrienols has been reported to cause mild itching in 7% of patients in one clinical study. Contact dermatitis has been reported in 33% of patients using a cream containing vitamin E as a mixture of tocopherols and tocotrienols. However, it is unclear if this effect resulted from tocopherols, tocotrienols, or the combination.”

Effects for Everolimus come from the ADVERSE REACTIONS section of its FDA label; effects for Tocotrienols come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 50,590 voluntary FDA FAERS reports for Everolimus that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Everolimus Is Prescribed For, and What Tocotrienols Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Everolimus is a prescription medicine with approved uses on its FDA label. Tocotrienols is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Everolimus is prescribed for: Everolimus is used to treat several serious conditions. In cancer, it is prescribed for advanced hormone receptor-positive, HER2-negative breast cancer (in postmenopausal women), certain neuroendocrine tumors of the pancreas, GI tract, or lung, and advanced renal cell carcinoma (kidney cancer) when other treatments have stopped working. It is also used for people with tuberous sclerosis complex (TSC) — a genetic condition that causes benign tumors to grow throughout the body. In TSC, it treats kidney tumors called angiomyolipomas, brain tumors called SEGA, and seizures.

In kidney transplant patients, it helps prevent the body from rejecting the new organ.

Tocotrienols has been studied for:

  • Breast cancer studied, not established Tocotrienols has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tocotrienols for breast cancer

    It is unclear if oral tocotrienols are beneficial for improving early breast cancer outcomes or preventing recurrence.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Everolimus on your own; if you are taking Tocotrienols for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Everolimus

This page covers Tocotrienols only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Everolimus page lists 156 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).

By severity: 5 major · 112 moderate · 39 minor.

From our pharmacist’s overview on the Everolimus page

“Everolimus (Afinitor, Zortress, Certican) has to stay in a narrow blood-level window, whether you take it after an organ transplant or for cancer, so treat this supplement list with real caution. Most of its 156 interacting ingredients can push those levels up or down, mainly by changing how the CYP3A4 enzyme breaks the drug down.”

About Tocotrienols

What is Tocotrienols?

Tocotrienols
  • Heart and cholesterol support
  • Antioxidant support
  • Liver health (fatty liver)
  • Bone health
  • Brain and nerve protection

Tocotrienols are a less common form of vitamin E with strong antioxidant activity studied mostly for cholesterol, liver, and heart health. Early research is interesting but far from conclusive, and a standard dose is not established. They are generally well tolerated, but talk with your pharmacist or doctor before using them, especially during pregnancy or if you take blood thinners.

Oil and extracts from plant seeds, bran, and fruits (such as rice bran, palm fruit, and annatto) · Softgel capsules, oil, combination vitamin E supplements

An interaction check asks whether these two react with each other — it does not ask whether Tocotrienols is a good idea for someone in your situation. Here is what our Tocotrienols record says about it on its own.

Tocotrienols: dosing

There is no official or standardized dose of tocotrienols. Amounts used in research have varied widely depending on the source and the condition being studied.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Tocotrienols and Everolimus Together: Common Questions

Is it safe to take Tocotrienols with Everolimus?
We do not list a known interaction between Tocotrienols and Everolimus. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Tocotrienols and Everolimus have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Tocotrienols and Everolimus used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Tocotrienols in each. That is a conversation for your prescriber, especially if Everolimus is being adjusted to a target.
How was the Tocotrienols and Everolimus combination checked?
Interactions in our licensed database are recorded against drug classes. Everolimus is filed under 7 classifications, and Tocotrienols has documented interactions with 1 drug class — none of Everolimus's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Tocotrienols interact with any other medications?
Yes. Tocotrienols has 122 documented drug interactions in our database — Everolimus is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Everolimus interact with any supplements?
Yes. Everolimus has documented interactions with 156 supplements in our database — Tocotrienols is not one of them. The Everolimus interaction page linked on this page lists every one, ranked by severity.
