Drug & supplement interaction

Dill + 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 Dill 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

Dill 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 Dill 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.

What to actually watch for

No Interaction Found — But Data Suggests Dill and Obinutuzumab May Share a Side Effect

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.

  • Diarrhea Additional detail

    Dill

    “Orally, there are case reports of individuals allergic to dill. In one case, symptoms, including swelling around the eyes, itching, rash, and chapped lips, occurred after a delay of 12 hours. In another case, immediate symptoms of anaphylaxis, as well as vomiting and diarrhea, occurred following intake and inhalation of foods cooked with dill.

    Topically, dill has resulted in contact dermatitis.”

How to take them

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

At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach. Most supplements — Dill 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 Dill 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 Dill

What is Dill?

  • Digestive upset and gas
  • Colic in infants (traditional)
  • Stimulating appetite
  • Bad breath
  • Menstrual discomfort

Dill is a common culinary herb that has long been used in traditional medicine for digestive complaints, but solid human evidence for any medicinal use is limited. It is generally considered safe in normal food amounts, while concentrated supplements or essential oil should be used with caution and discussed with a pharmacist or doctor.

Anethum graveolens · Apiaceae · Leaves (dill weed), seeds, and essential oil · Fresh or dried herb, seeds, tea, essential oil, capsules/extracts

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

Dill: dosing

There is no official or standardized medicinal dose for dill. As a food and seasoning, it is used freely to taste. As a tea, the seeds are sometimes steeped in hot water.For dill supplements, capsules, or extracts, the best advice is to follow the directions on the product label, since strength varies between products.

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 Dill and Obinutuzumab Together: Common Questions

Is it safe to take Dill with Obinutuzumab?
We do not list a known interaction between Dill 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 Dill and Obinutuzumab have any of the same side effects?
Yes — our sources link each of them separately to one 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 Dill 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 Dill 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 Dill interact with any other medications?
Yes. Dill has 87 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.
