Interaction report

Greek Sage and Fenfluramine

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 Fenfluramine 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 Fenfluramine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fenfluramine is filed under 2 classifications — cytochrome p450 2d6 (cyp2d6) substrates, oral drugs. Greek Sage has documented interactions with 1 drug class — the most serious being hexobarbital (moderate) — and none of Fenfluramine’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 Fenfluramine’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 Fenfluramine’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. 7 of them are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on mentioned in 43.8% of FDA reports for Fenfluramine
  • Serotonin syndrome Worth acting on
  • Dehydration Worth acting on
  • Unsteadiness Worth acting on
  • Raised blood pressure Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • Weight loss mentioned in 9.2% of FDA reports for Fenfluramine
  • Loss of bladder control
  • Reduced appetite mentioned in 11.3% of FDA reports for Fenfluramine

Showing the 10 most notable of 24 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 Fenfluramine. Read the label on DailyMed › Where a percentage is shown, it is the share of 4,666 voluntary FDA FAERS reports for Fenfluramine 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.

Everything else you take

See Every Supplement That Interacts With Fenfluramine

This page covers Greek Sage only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Fenfluramine page lists 77 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), 1,3-dmaa (moderate), Acacia Rigidula (moderate), Active Hexose Correlated Compound (ahcc) (moderate) and Ayahuasca (moderate).

By severity: 1 major · 56 moderate · 20 minor.

From our pharmacist’s overview on the Fenfluramine page

“Activated charcoal is the single major-rated risk here, and it earns that rating by soaking up fenfluramine (Pondimin) in the gut so that less of each dose ever reaches your blood. Fenfluramine is a serotonin-acting appetite suppressant, and a drug like that losing potency unpredictably is not a small thing, so I would treat this list…”

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.
