Alpine Ragwort + Dicloxacillin Injection

Dicloxacillin Injection brand name: Dynapen Injection.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Alpine Ragwort and Dicloxacillin Injection 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 Dicloxacillin Injection 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

Alpine Ragwort and Dicloxacillin Injection

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 Dicloxacillin Injection and Alpine Ragwort 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 Dicloxacillin Injection

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dicloxacillin Injection is filed under 3 classifications — antibiotic drugs, nephrotoxic drugs, seizure threshold lowering drugs. Alpine Ragwort has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Dicloxacillin Injection’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.

What to actually watch for

No Interaction Found — But Data Suggests Alpine Ragwort and Dicloxacillin Injection 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.

  • Liver problems Worth acting on Additional detail

    Alpine Ragwort

    “Orally, the major concern with alpine ragwort use is its pyrrolizidine alkaloid (PA) content. These constituents can cause liver injury. Chronic exposure to other plants containing hepatotoxic PA constituents is associated with veno-occlusive disease. Subacute veno-occlusive disease can cause vague symptoms, including colicky pains, vomiting, diarrhea, and ascites within several days;”

How to take them

Some Dicloxacillin Injection Products Have a Food Rule — Alpine Ragwort Should Not Break It

At least one FDA label for a product containing Dicloxacillin Injection says to take it on an empty stomach. Most supplements — Alpine Ragwort included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Dicloxacillin Injection on its own and move Alpine Ragwort to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Dicloxacillin Injection 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.

Patients weighing less than 40 kg (88 lbs) DRUG ADULTS CHILDREN Mild to Moderate Severe Mild to Moderate Severe Dicloxacillin 125 mg every 6 hours 250 mg every 6 hours 12.5 mg/kg/day 1 in equally divided doses every 6 hours 25 mg/kg/day 1 in equally divided doses every 6 hours Dicloxacillin is best absorbed when taken on an empty stomach, and should be administered at least 1 hour before or 2 hour

From the Dosage and Administration section of the FDA label we read for Dicloxacillin Injection — 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.

See Every Supplement That Interacts With Dicloxacillin Injection

This page covers Alpine Ragwort only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dicloxacillin Injection page lists 39 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Asarabacca (major), Siberian Cocklebur (major), Aristolochia (moderate), Bacillus Coagulans (moderate) and Bacillus Subtilis (moderate).

By severity: 2 major · 35 moderate · 2 minor.

From our pharmacist’s overview on the Dicloxacillin Injection page

“Dicloxacillin Injection (Dynapen) is a penicillin antibiotic used against serious bacterial infections, and this list earns real caution, chiefly for its two major-rated entries. Siberian cocklebur and asarabacca can each damage the kidneys, and pairing them with other kidney-stressing substances risks compounding that harm, so I would…”

About Alpine Ragwort

What is Alpine Ragwort?

Alpine Ragwort
  • Traditional wound care
  • Minor bleeding or bruises
  • Digestive complaints
  • Menstrual discomfort
  • Folk remedy for inflammation

Alpine Ragwort is a wild plant in the daisy family that contains pyrrolizidine alkaloids (PAs), which can severely damage the liver. There is no good scientific evidence that it works for any health condition, and the safety risks are serious. We do not recommend using it.

Senecio nemorensis · Asteraceae · Aerial parts (leaves, stems, and flowers) · Dried herb, tea, tincture, and traditional topical preparations

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

Alpine Ragwort: dosing

There is no established safe dose for Alpine Ragwort. Because of its toxic pyrrolizidine alkaloids, health authorities generally advise against taking it internally at all.We do not provide a recommended amount for this plant.

Taking Alpine Ragwort and Dicloxacillin Injection Together: Common Questions

Is it safe to take Alpine Ragwort with Dicloxacillin Injection?
We do not list a known interaction between Alpine Ragwort and Dicloxacillin Injection. 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 Alpine Ragwort and Dicloxacillin Injection 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.
Should I take Alpine Ragwort and Dicloxacillin Injection at the same time of day?
At least one FDA label for a product containing Dicloxacillin Injection says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Dicloxacillin Injection on its own and move Alpine Ragwort to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Alpine Ragwort and Dicloxacillin Injection combination checked?
Interactions in our licensed database are recorded against drug classes. Dicloxacillin Injection is filed under 3 classifications, and Alpine Ragwort has documented interactions with 1 drug class — none of Dicloxacillin Injection'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 Alpine Ragwort interact with any other medications?
Yes. Alpine Ragwort has 87 documented drug interactions in our database — Dicloxacillin Injection 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 Dicloxacillin Injection interact with any supplements?
Yes. Dicloxacillin Injection has documented interactions with 39 supplements in our database — Alpine Ragwort is not one of them. The Dicloxacillin Injection interaction page linked on this page lists every one, ranked by severity.
