Hydrangea + Ibritumomab
Ibritumomab brand name: Zevalin.
We found no known interaction between Hydrangea and Ibritumomab 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.
Hydrangea and Ibritumomab
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 Ibritumomab and Hydrangea 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Ibritumomab
Interactions in our licensed database are recorded against drug classes, not just single drug names. Ibritumomab is filed under a single classification — oral drugs. Hydrangea has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Ibritumomab’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.

From our pharmacist’s overview on the Ibritumomab page
“Activated charcoal is the entry to understand first if you receive ibritumomab (Zevalin), a radioactive antibody infusion used against non-Hodgkin lymphoma, and it is the one interaction here rated major. Charcoal can trap drug compounds that cycle between the gut and the bloodstream, so it may lower drug exposure even for a medicine t…”

About Hydrangea
What is Hydrangea?
- Kidney and bladder stones
- Urinary tract complaints
- Enlarged prostate symptoms
- Mild diuretic (increasing urine)
- Bladder infections (traditional use)
Hydrangea root has a long history in folk medicine, mainly for urinary and kidney stone complaints, but there is very little modern human research to confirm it works for any condition. Because safety data are limited and large amounts may be harmful, it is best to talk with a pharmacist or doctor before using it.
Hydrangea arborescens · Hydrangeaceae · Root and rhizome (underground stem) · Dried root, tincture, liquid extract, capsules, tea
An interaction check asks whether these two react with each other — it does not ask whether Hydrangea is a good idea for someone in your situation. Here is what our Hydrangea record says about it on its own.
Hydrangea: dosing
There is no well-established or standardized dose for hydrangea, because it has not been studied carefully in people. Traditional preparations used the dried root as a tea or tincture, but reliable, specific amounts are not available.If you choose to use a product, follow the directions on the label and do not exceed them.
