The bottom line No known interaction

We found no known interaction between Field Scabious and Cefdinir 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.

Field Scabious and Cefdinir

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 Cefdinir and Field Scabious 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 Field Scabious at all — not against Cefdinir, 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.

What Cefdinir’s Own FDA Label Lists

This is not an interaction — none of it involves Field Scabious. These are the most notable effects listed in the ADVERSE REACTIONS section of Cefdinir’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. 10 of them are worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • Severe muscle breakdown Worth acting on
  • Kidney problems Worth acting on mentioned in 11.1% of FDA reports for Cefdinir
  • Bleeding in the gut Worth acting on
  • A heart attack Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on

Showing the 10 most notable of 39 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 Cefdinir. Read the label on DailyMed › Where a percentage is shown, it is the share of 7,629 voluntary FDA FAERS reports for Cefdinir that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Field Scabious’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Field Scabious side to compare — that is a limit of the record, not a statement that Field Scabious has no side effects.

Overlapping uses

What Cefdinir Is Prescribed For, and What Field Scabious Has Been Studied For

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

Cefdinir is prescribed for: Cefdinir treats mild to moderate bacterial infections in adults, adolescents, and children caused by susceptible bacteria. It is used for community-acquired pneumonia, acute exacerbations of chronic bronchitis, acute maxillary sinusitis (sinus infection), pharyngitis/tonsillitis (strep throat), and uncomplicated skin and skin structure infections. In pediatric patients (ages 6 months through 12 years), cefdinir is also used to treat acute bacterial otitis media (middle ear infection). It should only be used for infections that are proven or strongly suspected to be caused by bacteria — not for viral illnesses like the common cold.

Field Scabious has been studied for:

  • Pharyngitis studied, not established Field Scabious has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Field Scabious for pharyngitis

    Although there has been interest in using oral field scabious for sore throat, there is insufficient reliable information about the clinical effects of field scabious for this purpose.

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 Cefdinir on your own; if you are taking Field Scabious for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Cefdinir

This page covers Field Scabious only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefdinir page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefdinir page

“Cefdinir (Omnicef) is a short-course antibiotic for ear, sinus, throat, and skin infections, and three of its 60 supplement interactions on file are rated major and deserve genuine care. Two herbs, Siberian cocklebur and asarabacca, can damage the kidneys, an added strain nobody needs while fighting an infection.”

About Field Scabious

What is Field Scabious?

  • Skin conditions like eczema and minor wounds
  • Cough and chest complaints
  • Sore throat
  • Mild digestive upset
  • Traditional 'blood cleansing' remedies

Field Scabious is a wild-growing herb used in European folk medicine, mostly for skin problems, coughs, and sore throats. There is very little modern scientific research to confirm any of these uses, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Knautia arvensis · Caprifoliaceae · Aerial parts (flowers, leaves, and stems), occasionally the root · Tea (infusion), tincture, dried herb, topical washes or compresses

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

Field Scabious: dosing

There is no established, standardized dose for Field Scabious. It has traditionally been prepared as a tea from the dried aerial parts or as a tincture, but reliable dosing guidelines from clinical research do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
