Interaction report

Greek Sage and Daratumumab

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 Daratumumab 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.

Showing the 10 most notable of 14 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 Daratumumab. Read the label on DailyMed › Where a percentage is shown, it is the share of 42,488 voluntary FDA FAERS reports for Daratumumab 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.

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.

From our Greek Sage monograph — the full record covers uses, side effects and every documented interaction.
