Drug & supplement interaction

Asparagus + Tazemetostat Hydrobromide

Tazemetostat Hydrobromide brand name: Tazverik.

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 Asparagus and Tazemetostat Hydrobromide 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

Asparagus and Tazemetostat Hydrobromide

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 Tazemetostat Hydrobromide and Asparagus 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.

How we checked

Why No Interaction Is Listed for Tazemetostat Hydrobromide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tazemetostat Hydrobromide is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Asparagus has documented interactions with 2 drug classes — the most serious being diuretic drugs (moderate) and lithium (moderate) — and none of Tazemetostat Hydrobromide’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 Asparagus and Tazemetostat Hydrobromide 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.

  • Shortness of breath Worth acting on Additional detail

    Asparagus

    “Orally and topically, asparagus can cause allergic reactions. They can occur in individuals sensitive to other members of the Liliaceae family, including onions, garlic, leeks, and chives. Ingestion of fresh or canned asparagus can cause itchy eyes, runny nose, coughing, urticaria, dysphagia, dyspnea, and anaphylaxis in sensitized people.”

Overlapping uses

What Tazemetostat Hydrobromide Is Prescribed For, and What Asparagus Has Been Studied For

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

Tazemetostat Hydrobromide is prescribed for: Tazverik (tazemetostat) tablets are used to treat adults and patients aged 16 and older with metastatic or locally advanced epithelioid sarcoma (a rare soft-tissue cancer) that cannot be completely removed by surgery. Tazverik is also used in adults with relapsed or refractory follicular lymphoma — meaning the lymphoma has come back or stopped responding to treatment — either when the tumor carries a specific EZH2 gene mutation (confirmed by an FDA-approved test) after at least two prior treatments, or when there are no other satisfactory treatment options. Both uses were approved based on response rates, and continued approval may depend on results from ongoing confirmatory studies.

Asparagus has been studied for:

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

    Asparagus for cancer

    Although there is interest in using oral asparagus for cancer, there is insufficient reliable information about the clinical effects of asparagus for this condition.

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 Tazemetostat Hydrobromide on your own; if you are taking Asparagus for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Tazemetostat Hydrobromide

This page covers Asparagus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tazemetostat Hydrobromide page lists 138 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 94 moderate · 41 minor.

From our pharmacist’s overview on the Tazemetostat Hydrobromide page

“Tazemetostat (Tazverik) is a targeted cancer medicine, and because a lot rides on keeping its dose steady, this interaction list deserves genuine care. Almost all 138 interacting ingredients act on the liver enzyme CYP3A4, which clears tazemetostat from the body.”

About Asparagus

What is Asparagus?

Asparagus
  • Mild fluid retention (diuretic)
  • Urinary tract support
  • Digestive health and fiber
  • General antioxidant and nutritional support
  • Traditional 'detox' or cleansing use

Asparagus is a nutritious vegetable that is safe and healthy to eat as part of a normal diet. Most of its claimed medicinal benefits, such as use as a diuretic or for urinary health, come from traditional use and early lab studies rather than strong human research. If you are considering concentrated asparagus supplements or extracts, talk to your pharmacist or doctor first.

Asparagus officinalis · Asparagaceae · Shoots (spears), rhizome, root, and juice · Whole vegetable (food), capsules, powders, extracts, tea, and juice

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

Asparagus: dosing

There is no standardized or proven medicinal dose for asparagus. As a vegetable, it can be eaten freely as part of a balanced diet.For supplements, extracts, powders, or teas, follow the directions on the product label, since strengths vary widely between products.

Taking Asparagus and Tazemetostat Hydrobromide Together: Common Questions

Is it safe to take Asparagus with Tazemetostat Hydrobromide?
We do not list a known interaction between Asparagus and Tazemetostat Hydrobromide. 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 Asparagus and Tazemetostat Hydrobromide have any of the same side effects?
Yes — our sources link each of them separately to 6 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 Asparagus and Tazemetostat Hydrobromide 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. This page lists the shared uses and how strong the evidence is for Asparagus in each. That is a conversation for your prescriber, especially if Tazemetostat Hydrobromide is being adjusted to a target.
How was the Asparagus and Tazemetostat Hydrobromide combination checked?
Interactions in our licensed database are recorded against drug classes. Tazemetostat Hydrobromide is filed under 2 classifications, and Asparagus has documented interactions with 2 drug classes — none of Tazemetostat Hydrobromide'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 Asparagus interact with any other medications?
Yes. Asparagus has 76 documented drug interactions in our database — Tazemetostat Hydrobromide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Tazemetostat Hydrobromide interact with any supplements?
Yes. Tazemetostat Hydrobromide has documented interactions with 138 supplements in our database — Asparagus is not one of them. The Tazemetostat Hydrobromide interaction page linked on this page lists every one, ranked by severity.
