Pulsatilla + Cefdinir

Cefdinir brand name: Omnicef.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Pulsatilla 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. 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.

Pulsatilla 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 Pulsatilla 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 Pulsatilla 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 to actually watch for

No Interaction Found — But Data Suggests Pulsatilla and Cefdinir May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Pulsatilla

    “Orally, fresh pulsatilla is a toxic gastrointestinal irritant (4,19). It can also cause kidney and urinary tract irritation (2).

    Topically, contact with the fresh plant can cause skin irritation, mucous membrane irritation, itching, and pustule formation known as ranunculus dermatitis (2).”

Effects for Cefdinir come from the ADVERSE REACTIONS section of its FDA label; effects for Pulsatilla come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Cefdinir

This page covers Pulsatilla 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 Pulsatilla

What is Pulsatilla?

  • Menstrual and PMS-related complaints
  • Anxiety, moodiness, and weepiness (traditional/homeopathic)
  • Earache and cold symptoms (homeopathic)
  • Eye irritation and sinus complaints
  • Sleep and restlessness

Pulsatilla is a flowering plant in the buttercup family that is most often used today in homeopathic (highly diluted) preparations. The fresh plant is toxic and irritating, so it must never be eaten raw, and high-quality human evidence for its benefits is lacking. Talk with your pharmacist or doctor before using any Pulsatilla product, and avoid it during pregnancy and breastfeeding.

Pulsatilla vulgaris · Ranunculaceae · Aerial parts (dried whole flowering plant); used dried, never fresh · Homeopathic pellets and liquid dilutions, dried herb, tincture

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

Pulsatilla: dosing

There is no well-established, standardized dose of Pulsatilla for any health condition. Homeopathic products come in different potencies (such as 6C or 30C) and are dosed according to the label or a practitioner's directions, not by milligrams.Because the raw plant is toxic, you should never make or take a homemade preparation.

About Cefdinir

What Is Cefdinir Used For?

Brand name: Omnicef

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.

Most-Reported Side Effects for Cefdinir

From FAERS, the FDA’s public side-effect reporting system (7,629 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Diarrhea 530 reports
Chronic kidney disease 485 reports

Taking Pulsatilla and Cefdinir Together: Common Questions

Is it safe to take Pulsatilla with Cefdinir?
We do not list a known interaction between Pulsatilla and Cefdinir. 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 Pulsatilla and Cefdinir have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Does Cefdinir interact with any supplements?
Yes. Cefdinir has documented interactions with 60 supplements in our database — Pulsatilla is not one of them. The Cefdinir interaction page linked on this page lists every one, ranked by severity.
