Omega-6 Fatty Acids + Everolimus
Everolimus brand names: Certican, Afinitor, Zortress, Afinitor Disperz.
We found no known interaction between Omega-6 Fatty Acids 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.
Omega-6 Fatty Acids 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 Omega-6 Fatty Acids 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Omega-6 Fatty Acids at all — not against Everolimus, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.
Omega-6 Fatty Acids safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Omega-6 Fatty Acids in Pregnancy & Breastfeeding
When consumed as part of the diet in amounts between 5% and 10% of daily calories according to the Dietary Reference Intake (DRI) Acceptable Macronutrient Distribution Range (AMDR).
When high amounts of omega-6 fatty acids are consumed in the diet. Population research suggests that the highest maternal intakes of omega-6 fatty acids (15.2-47.6 grams or 137-428 kcal daily) during pregnancy is associated with a 2.4-times greater odds of giving birth to an infant below the 10th percentile for birth weight when compared with the lowest maternal intakes (0.4-5.7 grams daily). In addition, population research in women with a history of atopy suggests that the highest blood levels of omega-6 fatty acids during the second trimester is associated with an increased odds of having a child develop atopic dermatitis by age 4-6 years when compared with the lowest intakes. There is insufficient reliable information available about supplemental omega-6 fatty acids; avoid using.

What Everolimus Is Prescribed For, and What Omega-6 Fatty Acids 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. Omega-6 Fatty Acids 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.

Cancer studied, not established Omega-6 Fatty Acids has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Omega-6 Fatty Acids for cancer
It is unclear if increased dietary intake of omega-6 fatty acids is beneficial for cancer prevention.
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 Omega-6 Fatty Acids 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 Omega-6 Fatty Acids 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 Omega-6 Fatty Acids
What is Omega-6 Fatty Acids?
- General nutrition and energy
- Skin conditions like eczema
- Inflammation support
- Heart and cholesterol health
- Nerve health (such as diabetic nerve discomfort)
Omega-6 fatty acids are essential fats your body needs but cannot make on its own, and most people get plenty from everyday foods like vegetable oils, nuts, and seeds. Supplements such as evening primrose or borage oil are sometimes used for skin or other concerns, but the evidence for added benefit is mixed, and balancing omega-6 with omega-3 fats matters more than taking more omega-6. Talk with your pharmacist or doctor before adding a supplement.
Dietary fats from plant oils, seeds, nuts, and some animal sources · Vegetable oils (corn, soybean, sunflower, safflower), capsules, evening primrose oil, borage oil, and softgels
An interaction check asks whether these two react with each other — it does not ask whether Omega-6 Fatty Acids is a good idea for someone in your situation. Here is what our Omega-6 Fatty Acids record says about it on its own.
Omega-6 Fatty Acids: dosing
There is no single standardized dose of omega-6 fatty acids that works for everyone, and most people meet their needs through diet alone. Health organizations describe omega-6 as an essential nutrient but focus on overall fat balance rather than a specific supplement amount.For supplements like evening primrose oil or borage oil, the right amount depends on the specific product and the GLA content.
