Drug & supplement interaction

Anti-inflammatory Diet + Nivolumab

Nivolumab brand name: Opdivo.

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 Anti-inflammatory Diet and Nivolumab 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

Anti-inflammatory Diet and Nivolumab

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 Nivolumab and Anti-inflammatory Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Anti-inflammatory Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Anti-inflammatory Diet at all — not against Nivolumab, 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.

Anti-inflammatory Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

Anti-inflammatory Diet safety at a glance

Anti-inflammatory... overall Generally safe For most people, this is a balanced, nutritious eating pattern that is safe to follow.
Pregnancy Use caution Generally healthy during pregnancy, but discuss nutrient needs and any restrictive changes with your doctor.
Breastfeeding Use caution A balanced version is usually fine, but avoid overly restrictive plans and check with your provider.

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 Anti-inflammatory Diet and Nivolumab 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 following Anti-inflammatory Diet while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Heartburn / Diarrhea / Nausea reported in 5.4% of FDA reports for Nivolumab Additional detail

    Anti-inflammatory Diet

    “Gastrointestinal symptoms such as upset stomach with diarrhea, gas, heartburn, and nausea have been reported.”

Effects for Nivolumab come from the ADVERSE REACTIONS section of its FDA label; effects for Anti-inflammatory Diet come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 96,645 voluntary FDA FAERS reports for Nivolumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Nivolumab Is Prescribed For, and What Anti-inflammatory Diet Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Nivolumab is a prescription medicine with approved uses on its FDA label. Anti-inflammatory Diet is an eating pattern: what follows is what researchers have looked at it for, and how strong that evidence is.

Nivolumab is prescribed for: Opdivo (nivolumab) is used to treat many types of cancer in adults, and some in patients 12 years and older. It can be used alone or in combination with other therapies depending on the cancer type and stage. Cancers it treats include melanoma (including after surgery to reduce the chance of the cancer coming back), non-small cell lung cancer, malignant pleural mesothelioma, advanced renal cell carcinoma (kidney cancer), classical Hodgkin lymphoma, squamous cell carcinoma of the head and neck, urothelial carcinoma (bladder cancer), colorectal cancer with specific genetic features (MSI-H or dMMR), hepatocellular carcinoma (liver cancer), esophageal cancer, gastroesophageal junction cancer, and gastric (stomach) cancer. Some uses require the tumor to test positive for a protein called PD-L1, and some are specific to certain stages of disease or prior treatments received.

Anti-inflammatory Diet has been studied for:

  • Renal cell carcinoma studied, not established Anti-inflammatory Diet has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Anti-inflammatory Diet for renal cell carcinoma

    It is unclear if an anti-inflammatory diet is beneficial for the prevention of renal cell carcinoma.

  • Liver cancer studied, not established Anti-inflammatory Diet has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Anti-inflammatory Diet for liver cancer

    It is unclear if an anti-inflammatory diet is beneficial for the prevention of liver cancer.

  • Esophageal cancer studied, not established Anti-inflammatory Diet has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Anti-inflammatory Diet for esophageal cancer

    It is unclear if an anti-inflammatory diet is beneficial for the prevention of esophageal cancer.

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 Nivolumab on your own; if you are taking Anti-inflammatory Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Nivolumab page

“Nivolumab (Opdivo) is an immunotherapy infusion that trains the body's own immune system to recognize and attack cancer cells, the kind of drug you might expect to carry a long list of supplement warnings. It does not.”

Eating pattern

About Anti-inflammatory Diet

What is Anti-inflammatory Diet?

  • Joint pain and arthritis
  • Heart health
  • Reducing chronic inflammation
  • Weight management
  • General wellness and disease prevention

An anti-inflammatory diet is an eating pattern that emphasizes vegetables, fruits, whole grains, beans, nuts, fish, and olive oil while limiting processed foods, added sugar, and refined carbohydrates. It is generally safe and broadly healthy, and some evidence links it to lower inflammation markers and better heart and joint health, though it is a supportive lifestyle approach rather than a cure. Talk with your doctor or a registered dietitian before making major changes, especially if you have a medical condition.

Whole-food eating pattern (meal plans, recipes, dietary guidelines)

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

Anti-inflammatory Diet: dosing

There is no set "dose" for an anti-inflammatory diet because it is an eating pattern, not a supplement. A common approach is to fill most of your plate with vegetables, fruits, whole grains, and beans; choose fish, nuts, and olive oil as main fat and protein sources; and limit sugary drinks, refined grains, processed meats, and ultra-processed snacks.If you buy any branded "anti-inflammatory" supplements or meal products, follow the label and do not assume more is better. A registered dietitian can help tailor the plan to your needs, and your pharmacist or doctor can help if you have health conditions.

Following Anti-inflammatory Diet While Taking Nivolumab: Common Questions

Is it safe to follow Anti-inflammatory Diet while taking Nivolumab?
We do not list a known interaction between Anti-inflammatory Diet and Nivolumab. 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 Anti-inflammatory Diet and Nivolumab have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Anti-inflammatory Diet and Nivolumab 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 Anti-inflammatory Diet in each. That is a conversation for your prescriber, especially if Nivolumab is being adjusted to a target.
Does Nivolumab interact with any supplements?
Yes. Nivolumab has documented interactions with 1 supplement in our database — Anti-inflammatory Diet is not one of them. The Nivolumab interaction page linked on this page lists every one, ranked by severity.
