The bottom line No known interaction

We found no known interaction between Uzara 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.

Interaction report

Uzara 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 Uzara 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

What Uzara Itself Has Been Linked To

This is not an interaction — nothing below involves Obinutuzumab. It is the side-effect record for Uzara on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Uzara, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An irregular heartbeat / Raised blood pressure Worth acting on Additional detail

    “Orally, uzara can cause cardiotoxic effects, especially in patients with pre-existing cardiovascular disease. In one case report, a 68-year-old female with diabetes and hypertension was admitted to the emergency room with reduced left-ventricular function, pulmonary edema, and arrhythmia.”

  • Swelling Additional detail

    Recorded for Uzara in the same Natural Medicines adverse-effect record shown under An irregular heartbeat / Raised blood pressure above.

Everything above comes from the Natural Medicines adverse-effect record for Uzara — 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 — Uzara Should Not Break It

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

What is Uzara?

  • Diarrhea
  • Stomach cramps
  • Menstrual cramps (dysmenorrhea)
  • Headaches
  • Digestive upset

Uzara is a traditional African root remedy used mainly for diarrhea and stomach cramps. Because it contains cardiac glycosides that can affect the heart, it should be used cautiously and for short periods only. Talk to a pharmacist or doctor before using it, especially if you have heart problems, are pregnant, or take heart medications.

Xysmalobium undulatum · Apocynaceae · Dried root · Liquid extract, tincture, tablets, drops

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

Uzara: dosing

There is no well-established standard dose for Uzara, and products vary in strength. The right amount depends on the specific preparation, such as drops, tincture, or tablets.The safest approach is to follow the directions on the product label and use it only for short periods. Do not exceed the recommended amount, since higher doses raise the risk of heart-related side effects.

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 Uzara and Obinutuzumab Together: Common Questions

Is it safe to take Uzara with Obinutuzumab?
We do not list a known interaction between Uzara 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 Uzara 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 Uzara 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 Uzara interact with any other medications?
Yes. Uzara has 133 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.
