Drug & supplement interaction

Aconite + Cefaclor

Cefaclor brand names: Ceclor CD, Ceclor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Aconite and Cefaclor 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 label for Cefaclor states a food rule worth keeping to, and 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.

Interaction report

Aconite and Cefaclor

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 Cefaclor and Aconite 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.

How we checked

Why No Interaction Is Listed for Cefaclor

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefaclor is filed under 6 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Aconite has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and stimulant drugs (moderate) — and none of Cefaclor’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Aconite and Cefaclor 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.

  • Chest pain Worth acting on Additional detail

How to take them

Some Cefaclor Products Have a Food Rule — Aconite Should Not Break It

At least one FDA label for a product containing Cefaclor says to take it with food. If you take Aconite on an empty stomach out of habit, keep them separate — and take Cefaclor with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cefaclor products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

DOSAGE AND ADMINISTRATION The absorption of cefaclor extended-release tablets is enhanced when it is administered with food.

From the Dosage and Administration section of the FDA label we read for Cefaclor — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Overlapping uses

What Cefaclor Is Prescribed For, and What Aconite Has Been Studied For

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

Cefaclor is prescribed for: Cefaclor treats a range of bacterial infections. The capsule and oral suspension forms are used for ear infections (otitis media), lower respiratory tract infections including pneumonia, strep throat and tonsillitis, urinary tract infections (including kidney infections and bladder infections), and skin and skin structure infections. The extended-release tablet form of Cefaclor is approved for a narrower set of uses: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin infections. Not all infections approved for the capsule or suspension are approved for the extended-release tablet — your prescriber will choose the right form for your infection.

Aconite has been studied for:

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

    Aconite for pneumonia

    Injectable aconite has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Oral aconite has not been evaluated for this use.

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

See Every Supplement That Interacts With Cefaclor

This page covers Aconite only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefaclor 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 Cefaclor page

“The entries worth understanding before any others on this cefaclor (Ceclor) page are the kidney risks and charcoal. Cefaclor is a cephalosporin antibiotic, typically a short course for ear, sinus, throat, or skin infections, and two herbs here, Siberian cocklebur and asarabacca, can damage the kidneys on their own, so pairing either wi…”

About Aconite

What is Aconite?

Aconite
  • Pain and nerve pain
  • Fever and cold or flu symptoms
  • Anxiety and restlessness (homeopathic use)
  • Inflammation and joint pain
  • Heart-related complaints (traditional use)

Aconite is a highly poisonous plant, and even small amounts of the raw or improperly processed root can cause severe, life-threatening reactions. There is no good scientific evidence that it safely treats any condition, and the only forms generally considered acceptable are extremely diluted homeopathic preparations. We strongly recommend avoiding raw or unprocessed aconite entirely and talking to a pharmacist or doctor before using any product containing it.

Aconitum napellus · Ranunculaceae · Root (and sometimes leaves), usually after processing · Highly diluted homeopathic pellets and liquids; processed roots in some traditional Asian medicine systems

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

Aconite: dosing

There is no safe, established standard dose of aconite for any condition. The line between a "traditional" amount and a deadly amount is extremely thin, which is a major reason this plant is considered so dangerous.The only forms generally considered acceptable are extremely diluted homeopathic products, which contain little or no actual plant material. If you choose to use such a product, follow the label exactly and do not exceed it.

Taking Aconite and Cefaclor Together: Common Questions

Is it safe to take Aconite with Cefaclor?
We do not list a known interaction between Aconite and Cefaclor. 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 Aconite and Cefaclor have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
Should I take Aconite and Cefaclor at the same time of day?
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Aconite on an empty stomach out of habit, keep them separate and take Cefaclor with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Cefaclor products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Aconite and Cefaclor 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 Aconite in each. That is a conversation for your prescriber, especially if Cefaclor is being adjusted to a target.
How was the Aconite and Cefaclor combination checked?
Interactions in our licensed database are recorded against drug classes. Cefaclor is filed under 6 classifications, and Aconite has documented interactions with 2 drug classes — none of Cefaclor's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Aconite interact with any other medications?
Yes. Aconite has 278 documented drug interactions in our database — Cefaclor is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Cefaclor interact with any supplements?
Yes. Cefaclor has documented interactions with 60 supplements in our database — Aconite is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
