Winter Savory 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 Winter Savory 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.

Winter Savory safety at a glance

Winter Savory overall Use caution Likely safe as a food seasoning, but concentrated extracts and essential oil are not well studied in people.
Pregnancy Avoid Avoid medicinal or essential oil amounts during pregnancy due to a lack of safety data.
Breastfeeding Use caution Food amounts are likely fine, but avoid concentrated supplements and the essential oil without medical advice.

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. Winter Savory has documented interactions with 1 drug class — the most serious being lithium (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 Winter Savory. 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. Winter Savory’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Winter Savory side to compare — that is a limit of the record, not a statement that Winter Savory has no side effects.

Everything else you take

See Every Supplement That Interacts With Fenfluramine

This page covers Winter Savory 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 Winter Savory

What is Winter Savory?

  • Digestive upset and gas
  • Sore throat
  • Antimicrobial
  • Cough
  • Seasoning food

Winter savory is a culinary herb in the mint family used mainly to flavor food and, in folk medicine, to ease digestion and sore throats. Solid human research is very limited, so it should not be relied on to treat any health condition. It is generally considered safe in food amounts, but concentrated extracts and the essential oil call for more caution.

Satureja montana · Lamiaceae · Leaves, flowering tops, and essential oil · Culinary herb, tea, dried herb, capsules, essential oil

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

Winter Savory: dosing

There is no established, standardized medicinal dose for winter savory. Most people simply use it as a seasoning in cooking, which is considered the safest way to enjoy it.If you choose a tea, capsule, or essential oil product, follow the directions on the product label and do not exceed the suggested amount. Essential oils are very concentrated and require special handling and dilution.
