Supplements and Sirolimus.

Every documented pair, every citation. Below: 2 documented pairs grouped by mechanism.

Sirolimus, sold under the brand name Rapamune, is an mTOR inhibitor used as a post-transplant immunosuppressant. The therapeutic window is narrow and CYP3A4-driven.

Below are the 2 documented pairs we have explicitly assessed against Sirolimus in the Distil database: 2 red. The pairs cluster around 1 mechanism: CYP3A4 inhibition. Every call is cited to either a clinical reference (PMID) or the British National Formulary. Anything not on this list is either still to be assessed or beyond our database scope. The checker beneath surfaces assessments by supplement, and the missing-item form at the bottom of the page routes any uncatalogued supplement into our next curation pass.

Documented interactions

CYP3A4 inhibition

Red Curcumin

Curcumin can slow how the body clears sirolimus, which may push sirolimus blood levels higher than intended. We treat this as a do-not-combine pair outside direct transplant-team supervision.

BNF: Sirolimus

Reviewer-flagged: awaiting clinical-reviewer sign-off.

Red Quercetin

Quercetin can slow how the body clears sirolimus, which may push sirolimus blood levels higher than intended. We treat this as a do-not-combine pair outside direct transplant-team supervision.

BNF: Sirolimus

Reviewer-flagged: awaiting clinical-reviewer sign-off.

What this list does not say. Pairs not flagged here are not implicitly safe. They are either not yet in our database, or fall outside our inclusion scope (food-supplement interactions only; for drug-drug interactions, the BNF is authoritative). Use the checker below to surface any supplement, and submit a missing item if you take something we have not catalogued.

How we decide

How we grade severity, choose what's in scope, and what we exclude.

Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

If a supplement or medication you take isn't in our autocomplete, tell us and we'll add it in the next quarterly update.

Thanks. Logged for the next quarterly update.

Distil's interactions database is reviewed and updated every quarter. We grade evidence transparently and publish our methodology, including every database change, at /about/methodology. This tool is information, not a substitute for clinical judgement. If you take medication and supplements together, your GP or pharmacist can review your full regimen against your medical history. If you want a comprehensive personalised stack reasoned against this same database, the Distil report is the next step up.
