Drug & supplement interaction

Eyebright + Sirolimus (albumin bound)

Sirolimus (albumin bound) brand name: Fyarro.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Eyebright and Sirolimus (albumin bound) 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.

Interaction report

Eyebright and Sirolimus (albumin bound)

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 Sirolimus (albumin bound) and Eyebright 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.

Eyebright safety at a glance

Eyebright overall Use caution Likely safe in small amounts as a tea, but using homemade or non-sterile preparations directly in the eye is risky.
Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy.
Breastfeeding Avoid There is not enough safety information, so avoid use while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Sirolimus (albumin bound)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sirolimus (albumin bound) is filed under 4 classifications — including immunosuppressants, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Eyebright has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Sirolimus (albumin bound)’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 Eyebright and Sirolimus (albumin bound) 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. One of them is worth acting on rather than waiting out — marked below.

Overlapping uses

What Sirolimus (albumin bound) Is Prescribed For, and What Eyebright Has Been Studied For

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

Sirolimus (albumin bound) is prescribed for: Fyarro (sirolimus with albumin) injection is approved to treat adult patients with locally advanced unresectable or metastatic malignant perivascular epithelioid cell tumor (PEComa) — a rare type of soft-tissue tumor. This includes tumors that cannot be surgically removed or that have spread to other parts of the body.

Eyebright has been studied for:

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

    Eyebright for cancer

    Although there has been interest in using oral eyebright for cancer, there is insufficient reliable information about the clinical effects of eyebright for this purpose.

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 Sirolimus (albumin bound) on your own; if you are taking Eyebright for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Sirolimus (albumin bound)

From our pharmacist’s overview on the Sirolimus (albumin bound) page

“Fyarro, the albumin-bound form of sirolimus used to treat advanced malignant PEComa, a rare cancer, is a medication I would guard carefully from supplement interference, and the 171 ingredients on this page show why. Most of them (121 through the CYP3A4 enzyme, 37 through the P-glycoprotein transporter) can shift how much sirolimus act…”

About Eyebright

What is Eyebright?

Eyebright
  • Eye irritation and redness
  • Conjunctivitis (pink eye)
  • Eye strain
  • Allergy and cold-related eye symptoms
  • Nasal congestion and hay fever

Eyebright is a traditional herb long used for minor eye irritation, redness, and allergy symptoms, but high-quality human studies are very limited. There is not enough reliable evidence to confirm it works, and using non-sterile herbal preparations in the eye carries a real risk of infection, so talk to your pharmacist or doctor before trying it.

Euphrasia officinalis · Orobanchaceae · Aerial parts (leaves, stems, and flowers) · Tea, eye drops, tincture, capsules, homeopathic preparations, compresses

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

Eyebright: dosing

There is no standardized or well-established dose for eyebright. Traditional use as a tea typically involves steeping the dried herb in hot water, but amounts vary widely between products and sources.If you choose to use a commercial eyebright product, follow the directions on the label and choose products from reputable manufacturers. For anything used in or near the eye, only use products that are specifically made and labeled as sterile eye preparations.

Taking Eyebright and Sirolimus (albumin bound) Together: Common Questions

Is it safe to take Eyebright with Sirolimus (albumin bound)?
We do not list a known interaction between Eyebright and Sirolimus (albumin bound). 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 Eyebright and Sirolimus (albumin bound) have any of the same side effects?
Yes — our sources link each of them separately to 8 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 Eyebright and Sirolimus (albumin bound) 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.

That is a conversation for your prescriber, especially if Sirolimus (albumin bound) is being adjusted to a target.
How was the Eyebright and Sirolimus (albumin bound) combination checked?
Interactions in our licensed database are recorded against drug classes. Sirolimus (albumin bound) is filed under 4 classifications, and Eyebright has documented interactions with 1 drug class — none of Sirolimus (albumin bound)'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 Eyebright interact with any other medications?
Yes. Eyebright has 86 documented drug interactions in our database — Sirolimus (albumin bound) is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
