Drug & supplement interaction

Artichoke + Obinutuzumab

Obinutuzumab brand name: Gazyva.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Artichoke and Obinutuzumab 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 label for Obinutuzumab states a food rule worth keeping to, and 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

Artichoke and Obinutuzumab

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 Obinutuzumab and Artichoke 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.

Artichoke safety at a glance

Artichoke overall Use caution Generally well tolerated as a food and short-term supplement, but quality and dosing vary by product.
Pregnancy Avoid Not enough safety information exists, so it is best avoided in supplement form during pregnancy.
Breastfeeding Avoid Safety during breastfeeding has not been established, so it is best avoided.

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

What to actually watch for

No Interaction Found — But Data Suggests Artichoke and Obinutuzumab 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.

  • An allergic reaction Worth acting on Additional detail

    Artichoke

    “Artichoke can cause an allergic reaction in some patients. Patients sensitive to the Asteraceae/Compositae family may be at the greatest risk. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. Topically, allergic contact dermatitis can occur with the use of artichoke. This has been attributed to the constituent cynaropicrin (11,52206,52226,52230).”

    Obinutuzumab

    Listed in the ADVERSE REACTIONS section of the FDA label for Obinutuzumab. Read the label on DailyMed ›

Reported for Artichoke but not commonly for Obinutuzumab: a bowel blockage, stomach upset, a severe allergic reaction and chest pain.

Effects for Obinutuzumab come from the ADVERSE REACTIONS section of its FDA label; effects for Artichoke come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Obinutuzumab Products Have a Food Rule — Artichoke Should Not Break It

At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach. Most supplements — Artichoke included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Obinutuzumab on its own and move Artichoke to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Obinutuzumab products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

650–1,000 mg acetaminophen At least 30 minutes before GAZYVA infusion.

From the Dosage and Administration section of the FDA label we read for Obinutuzumab — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Artichoke

What is Artichoke?

Artichoke
  • High cholesterol
  • Indigestion and heartburn
  • Constipation and bloating
  • Liver and gallbladder support
  • General digestive health

Artichoke leaf extract is a generally well-tolerated supplement that may have a mild cholesterol-lowering effect and is often used for indigestion, though the evidence is modest. It is not a replacement for proven treatments, so talk with your pharmacist or doctor before using it, especially if you have a medical condition.

Cynara cardunculus var. scolymus · Asteraceae · Leaves (most common in supplements); also flower buds and roots · Capsules, tablets, liquid extracts, tea, and as a food (the edible flower bud)

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

Artichoke: dosing

There is no single official dose for artichoke supplements. The right amount depends on the specific product and the type of extract used, since the strength can vary widely between brands.The best approach is to follow the directions on the product label and choose a reputable, standardized product.

About Obinutuzumab Injection

What Is Obinutuzumab Injection Used For?

Brand name: Gazyva

Gazyva is used to treat three conditions. For chronic lymphocytic leukemia (CLL), it is given in combination with chlorambucil in patients who have not been treated before. For follicular lymphoma (FL), it is used either with bendamustine (for patients whose disease came back or stopped responding to a rituximab-based regimen) or with chemotherapy (for previously untreated advanced disease) — in both cases followed by Gazyva alone as maintenance therapy.

Gazyva is also approved for active lupus nephritis — a type of kidney inflammation caused by lupus — in adults who are already receiving standard therapy for the condition.

Taking Artichoke and Obinutuzumab Together: Common Questions

Is it safe to take Artichoke with Obinutuzumab?
We do not list a known interaction between Artichoke and Obinutuzumab. 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 Artichoke and Obinutuzumab have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Should I take Artichoke and Obinutuzumab at the same time of day?
At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Obinutuzumab on its own and move Artichoke to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Artichoke interact with any other medications?
Yes. Artichoke has 363 documented drug interactions in our database — Obinutuzumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
