Drug & supplement interaction

Nasturtium + Cefuroxime

Cefuroxime brand names: Ceftin, Kefurox, Zinacef.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Nasturtium and Cefuroxime 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Nasturtium and Cefuroxime

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 Cefuroxime and Nasturtium 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 Nasturtium at all — not against Cefuroxime, 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.

Nasturtium safety at a glance

Nasturtium overall Use caution Generally considered safe as a food, but concentrated extracts have limited safety data.
Pregnancy Avoid Not enough safety information; medicinal amounts are best avoided during pregnancy.
Breastfeeding Use caution Safety during breastfeeding is not well studied, so caution is advised.

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

What to actually watch for

No Interaction Found — But Data Suggests Nasturtium and Cefuroxime May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • A skin rash Additional detail

    Nasturtium

    “Orally, large amounts of nasturtium or benzyl mustard oil, a constituent of nasturtium, can cause gastrointestinal tract irritation (2,18). Large amounts of nasturtium can cause albuminuria due to glomerular and tubular damage (2).

    Topically, contact with the nasturtium plant and its benzyl mustard oil constituent can cause skin and mucosal irritation (2,18).”

    Listed in the ADVERSE REACTIONS section of the FDA label for Cefuroxime. Read the label on DailyMed ›

Effects for Cefuroxime come from the ADVERSE REACTIONS section of its FDA label; effects for Nasturtium come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 15,671 voluntary FDA FAERS reports for Cefuroxime that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Cefuroxime Is Prescribed For, and What Nasturtium Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Cefuroxime is a prescription medicine with approved uses on its FDA label. Nasturtium is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Cefuroxime is prescribed for: Cefuroxime Axetil tablets treat several common bacterial infections in adults and children, including strep throat, ear infections (in children who can swallow tablets), sinus infections, acute flare-ups of chronic bronchitis, uncomplicated skin infections, urinary tract infections, uncomplicated gonorrhea, and early Lyme disease. The injectable forms — Cefuroxime and Cefuroxime sodium — are used in hospital or clinical settings to treat more serious infections, including pneumonia and other lower respiratory tract infections, urinary tract infections, skin and skin-structure infections, septicemia (blood infection), meningitis (infection of the brain and spinal cord lining), gonorrhea, and bone and joint infections. The injectable forms are also used to help prevent infections in certain surgical procedures.

Nasturtium has been studied for:

  • Respiratory tract infections studied, not established Nasturtium has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Nasturtium for respiratory tract infections

    Preliminary clinical research in patients with a history of recurrent respiratory tract infections (RTIs) shows that taking a specific combination product (Angocin Anti-Infekt N, Repha GmbH) containing a total of 320-400 mg horseradish root and 800-1000 mg nasturtium daily for 12 weeks modestly decreases the rate of new RTIs when compared with placebo.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Cefuroxime on your own; if you are taking Nasturtium for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Cefuroxime page

“Cefuroxime (Ceftin, Zinacef) treats everyday infections like sinusitis and bronchitis, and three of its 60 listed supplement interactions rate major, enough that this page deserves unhurried attention.

About Nasturtium

What is Nasturtium?

  • Urinary tract infections
  • Respiratory infections and congestion
  • Antimicrobial support
  • Wound and skin care (topical)
  • Mild cold and cough symptoms

Nasturtium is an edible garden plant traditionally used for urinary and respiratory infections, often combined with horseradish in herbal products. Some lab studies suggest it has antimicrobial activity, but high-quality human evidence is limited. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have kidney or stomach problems.

Tropaeolum majus · Tropaeolaceae · Leaves, flowers, and seeds · Fresh leaves and flowers (food/salad), dried herb, tea, capsules, tinctures, and combination herbal products

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

Nasturtium: dosing

There is no well-established standardized dose for nasturtium. Amounts vary widely depending on whether you use fresh leaves, dried herb, tea, capsules, or a combination product.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Nasturtium and Cefuroxime Together: Common Questions

Is it safe to take Nasturtium with Cefuroxime?
We do not list a known interaction between Nasturtium and Cefuroxime. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Nasturtium and Cefuroxime have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Nasturtium and Cefuroxime used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Nasturtium in each. That is a conversation for your prescriber, especially if Cefuroxime is being adjusted to a target.
Does Cefuroxime interact with any supplements?
Yes. Cefuroxime has documented interactions with 60 supplements in our database — Nasturtium is not one of them. The Cefuroxime interaction page linked on this page lists every one, ranked by severity.
