Great Plantain + Sirolimus
Sirolimus brand name: Rapamune.
We found no known interaction between Great Plantain and Sirolimus 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.
Great Plantain and Sirolimus
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 and Great Plantain 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.
Great Plantain 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.
Why No Interaction Is Listed for Sirolimus
Interactions in our licensed database are recorded against drug classes, not just single drug names. Sirolimus is filed under 5 classifications — including immunosuppressants, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Great Plantain has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Sirolimus’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.

Great Plantain has 2 moderate known drug interactions in our database — Sirolimus isn’t one of them. If you take anything else, check it against the full list below.

From our pharmacist’s overview on the Sirolimus page
“Sirolimus (Rapamune) is the anti-rejection medicine transplant patients depend on, and it is a narrow-therapeutic-index drug, meaning small shifts in its blood level can invite rejection on one side or toxicity on the other. That is why the 188 supplements on this page deserve genuine wariness, starting with the three rated major.”
