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

We found no known interaction between Ground Ivy 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.

Ground Ivy 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 Ground Ivy 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Ground Ivy at all — not against Obinutuzumab, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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

What Ground Ivy Itself Has Been Linked To

This is not an interaction — nothing below involves Obinutuzumab. It is the side-effect record for Ground Ivy on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Ground Ivy, this list is the first place to look.

  • Itching Additional detail

    “Orally and topically, ground ivy seems to be well tolerated. However, a thorough evaluation of safety outcomes has not been conducted.

    Topically: Itching and stinging.”

    Ground Ivy · Natural Medicines adverse-effect record, reported in pruritus.

    “Skin stinging and itching has been reported in patients applying a ground ivy extract 1% lotion twice daily. This occurred during the first two weeks of treatment, but disappeared upon further treatment.”

    Ground Ivy · Natural Medicines adverse-effect record, reported in pruritus.

Everything above comes from the Natural Medicines adverse-effect record for Ground Ivy — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Obinutuzumab’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Obinutuzumab column appears here.

How to take them

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

At least one FDA label for a product containing Obinutuzumab says to take it on an empty stomach. Most supplements — Ground Ivy 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 Ground Ivy 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. See the Obinutuzumab drug page ›

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 Ground Ivy

What is Ground Ivy?

Ground Ivy
  • Coughs and upper respiratory complaints
  • Digestive upset
  • Kidney and bladder complaints
  • Mild inflammation or arthritis
  • Menstrual irregularities

Ground ivy is a creeping plant in the mint family that has a long history of folk use for coughs, digestive problems, and urinary complaints. Modern human studies are lacking, so its benefits are unproven. Because of safety concerns, it should be avoided during pregnancy and breastfeeding and used cautiously by everyone else.

Glechoma hederacea · Lamiaceae · Above-ground parts (leaves, flowers, and stems) · Tea, tincture, dried herb, capsules, and occasionally fresh herb

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

Ground Ivy: dosing

There is no well-established or standardized dose for ground ivy. Traditional use most often involved a tea made from the dried leaves and flowering tops, or a tincture.Because product strength varies widely and reliable dosing studies are lacking, the safest approach is to follow the directions on a specific product's label and to start low.

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 Ground Ivy and Obinutuzumab Together: Common Questions

Is it safe to take Ground Ivy with Obinutuzumab?
We do not list a known interaction between Ground Ivy 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.
Should I take Ground Ivy 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 Ground Ivy 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.
