The bottom line No known interaction

We found no known interaction between Greek Sage 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 label for Nivolumab states a food rule worth keeping to.

Greek Sage 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 Greek Sage 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.

Greek Sage safety at a glance

Greek Sage overall Use caution Likely safe in food and tea amounts, but concentrated extracts and the essential oil need more caution.
Pregnancy Avoid Avoid medicinal or concentrated amounts during pregnancy due to limited safety data.
Breastfeeding Use caution Limited data; avoid concentrated forms and check with your doctor.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Nivolumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nivolumab is filed under a single classification — antineoplastics. Greek Sage has documented interactions with 1 drug class — the most serious being hexobarbital (moderate) — and none of Nivolumab’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Nivolumab’s Own FDA Label Lists

This is not an interaction — none of it involves Greek Sage. 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 take both. 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

Showing the 10 most notable of 67 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

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. Greek Sage’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Greek Sage side to compare — that is a limit of the record, not a statement that Greek Sage has no side effects.

How to take them

Some Nivolumab Products Have a Food Rule — Greek Sage Should Not Break It

At least one FDA label for a product containing Nivolumab says to take it on an empty stomach. Most supplements — Greek Sage included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Nivolumab on its own and move Greek Sage 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 Nivolumab 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.

Table 2: Recommended Dosages of Intravenous OPDIVO in Combination with Other Therapeutic Agents Indication Recommended OPDIVO Dosage Duration of Therapy Unresectable or metastatic melanoma 1 mg/kg every 3 weeks with ipilimumab 3 mg/kg In combination with ipilimumab for a maximum of 4 doses or until unacceptable toxicity, whichever occurs earlier Adult patients and pediatric patients aged 12 years

From the Dosage and Administration section of the FDA label we read for Nivolumab — 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.

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 Greek Sage

What is Greek Sage?

  • Sore throat and mouth irritation
  • Digestive upset
  • Memory and cognition support
  • Antimicrobial purposes
  • Flavoring and aromatherapy

Greek sage (Salvia fruticosa) is a Mediterranean herb traditionally used as a tea and flavoring, and popularly for sore throats and digestion. Solid human research on its health benefits is limited, so most uses are based on tradition or early lab studies. It is generally considered safe in food amounts, but talk to a pharmacist or doctor before using concentrated extracts or essential oils.

Salvia fruticosa · Lamiaceae · Leaves and essential oil · Tea, dried leaf, capsules, essential oil, extracts

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

Greek Sage: dosing

There is no official standardized dose of Greek sage. Traditional use is usually a cup of tea made from a small amount of dried leaf.For capsules, extracts, or essential oil products, follow the directions on the label, since the strength varies a lot between products.

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. Your oncologist will determine which use applies to your situation.

Should I take Greek Sage and Nivolumab at the same time of day?
At least one FDA label for a product containing Nivolumab 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.

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.

Interactions in our licensed database are recorded against drug classes. Nivolumab is filed under 1 classification, and Greek Sage has documented interactions with 1 drug class — none of Nivolumab's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
