The bottom line No known interaction

We found no known interaction between Clary Sage and Fosfomycin 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.

Clary Sage and Fosfomycin

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 Fosfomycin and Clary 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Clary Sage at all — not against Fosfomycin, 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.

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.

Clary Sage safety at a glance

Clary Sage overall Use caution Generally considered safe as a diluted essential oil for aromatherapy, but it should not be taken by mouth.
Pregnancy Avoid Often discouraged in pregnancy because it is traditionally linked to uterine activity, so avoid it.
Breastfeeding Avoid There is not enough safety information, so it is best avoided while breastfeeding.

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

What Fosfomycin’s Own FDA Label Lists

This is not an interaction — none of it involves Clary Sage. These are the most notable effects listed in the ADVERSE REACTIONS section of Fosfomycin’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Low potassium Worth acting on
  • An irregular heartbeat Worth acting on
  • A low white blood cell count Worth acting on
  • An allergic reaction Worth acting on
  • Stomach pain
  • Diarrhea
  • Vomiting
  • Headache
  • Nausea

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

The most serious there right now: Activated Charcoal (major), Bacillus Coagulans (moderate), Bacillus Subtilis (moderate), Bifidobacterium Animalis Subsp. Lactis (moderate) and Bifidobacterium Bifidum (moderate).

From our pharmacist’s overview on the Fosfomycin page

“Fosfomycin (Monurol) is often given as a single sachet to knock out a bladder infection, so you get one chance to absorb the full dose, and that is exactly where this list deserves real care. The clearest hazard is activated charcoal, which binds medicines in the gut and can cut how much fosfomycin your body actually takes in.”

About Clary Sage

What is Clary Sage?

  • Stress and anxiety
  • Menstrual cramps
  • Menopause symptoms
  • Aromatherapy and relaxation
  • Skin care

Clary sage is a Mediterranean herb most often used as an essential oil for aromatherapy and to ease stress or menstrual discomfort. Evidence for these uses is limited and mostly from small studies, and the oil should never be swallowed and should always be diluted before skin contact.

Salvia sclarea · Lamiaceae · Flowering tops and leaves (essential oil) · Essential oil, aromatherapy blends, diluted topical oils

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

Clary Sage: dosing

There is no official or standardized dose for clary sage, and it is not meant to be taken by mouth as a supplement.For aromatherapy, people typically add a few drops to a diffuser or dilute a small amount in a carrier oil before applying it to the skin.

About Fosfomycin

What Is Fosfomycin Used For?

Brand name: Monurol

Fosfomycin is an antibiotic used to treat urinary tract infections (UTIs) caused by specific bacteria. The right form depends on how serious the infection is.

Oral forms (Fosfomycin Tromethamine and Monurol) are approved only for uncomplicated UTIs — also called acute cystitis — in women 18 and older, caused by E. coli or Enterococcus faecalis. They are not for kidney infections or abscesses around the kidney. Contepo (intravenous) is approved for adults 18 and older with complicated UTIs, including acute pyelonephritis (kidney infection), caused by susceptible E. coli or Klebsiella pneumoniae.
