Low Oxalate 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 Low Oxalate Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Low Oxalate Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Low Oxalate 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.

Low Oxalate 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.

What to actually watch for

What Nivolumab’s Own FDA Label Lists

This is not an interaction — none of it involves Low Oxalate Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Nivolumab’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you follow Low Oxalate Diet and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • A change in thyroid levels Worth acting on
  • A stroke or mini-stroke Worth acting on
  • Severe muscle breakdown Worth acting on
  • Dehydration Worth acting on
  • Trouble swallowing Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Nivolumab. Read the label on DailyMed › 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. Low Oxalate Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Low Oxalate Diet side to compare — that is a limit of the record, not a statement that Low Oxalate Diet has no side effects.

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.”

About Low Oxalate Diet

What is Low Oxalate Diet?

  • Prevention of calcium-oxalate kidney stones
  • Reducing high urine oxalate levels
  • Management of recurrent kidney stones
  • Hyperoxaluria

A low oxalate diet limits foods high in oxalate (like spinach, rhubarb, nuts, and certain beans) to help lower the amount of oxalate in your urine. It is most often recommended for people who form calcium-oxalate kidney stones, but it works best alongside other steps like staying well hydrated and getting enough dietary calcium. Talk with your doctor, pharmacist, or a dietitian before making major diet changes.

Dietary plan (meal planning, food lists)

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

Low Oxalate Diet: dosing

There is no single "dose" for a low oxalate diet. Recommendations vary, but a common approach is to limit total daily oxalate intake and focus on avoiding the highest-oxalate foods. Because exact targets differ from person to person, your provider or dietitian can set a goal that fits you.General supportive steps often recommended alongside the diet include drinking enough fluid to keep urine pale, getting adequate calcium from food, and limiting excess salt and animal protein.

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.
