Drug & supplement interaction

Groundsel + Cefepime

Cefepime brand name: Maxipime.

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 Groundsel and Cefepime 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.

Groundsel and Cefepime

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 Cefepime and Groundsel 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 Cefepime

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefepime is filed under 5 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Groundsel has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Cefepime’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 Groundsel and Cefepime 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.

  • Diarrhea / Vomiting Additional detail

    Groundsel

    “Orally, groundsel may cause hepatotoxicity due to its pyrrolizidine alkaloid (PA) constituents. Chronic exposure hepatotoxic PAs is associated with veno-occlusive disease. Subacute veno-occlusive disease causes vague symptoms with persistent liver enlargement. Symptoms of acute veno-occlusive disease include colicky pains in epigastrium, vomiting and diarrhea, and ascites formation within several days.”

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

Reported for Groundsel but not commonly for Cefepime: liver problems and raised blood pressure.

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

Special populations

Groundsel in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally. Groundsel products can contain pyrrolizidine alkaloid (PA) constituents, which might be teratogenic and hepatotoxic. There is insufficient reliable information available about the safety of using groundsel products that do not contain hepatotoxic PAs during pregnancy. However, dietary supplements sold in the US are not required to include the amount of PAs they contain; therefore, all preparations used orally containing groundsel should be considered likely unsafe.

Lactation Likely Unsafe

When used orally. Hepatotoxic PA constituents in groundsel are excreted in milk. There is insufficient reliable information available about the safety of using groundsel products that do not contain hepatotoxic PAs during lactation. However, dietary supplements sold in the US are not required to include the amount of PAs they contain; therefore, all preparations used orally containing groundsel should be considered likely unsafe.

See Every Supplement That Interacts With Cefepime

This page covers Groundsel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefepime page lists 43 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 2 major · 39 moderate · 2 minor.

From our pharmacist’s overview on the Cefepime page

“Cefepime (Maxipime) is a strong hospital antibiotic reserved for serious infections, and its interaction list warrants genuine caution, led by two major-rated herbs that can harm the kidneys: Siberian cocklebur and asarabacca, which is often contaminated with aristolochic acid, a kidney toxin the FDA considers unsafe. That matters more…”

About Groundsel

What is Groundsel?

  • Menstrual complaints
  • Digestive upset
  • Minor wounds (topical)
  • Sore gums or mouth
  • Mild aches

Groundsel is a common weed traditionally used as a folk remedy, but it contains pyrrolizidine alkaloids that can cause serious liver damage. There is no reliable evidence that it works for any condition, and most health authorities consider it unsafe to take internally. We do not recommend using it.

Senecio vulgaris · Asteraceae · Aerial parts (leaves, stems, flowers) · Tea, dried herb, tincture, topical poultice

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

Groundsel: dosing

There is no established safe dose for groundsel. Because of its toxic pyrrolizidine alkaloids, no standardized, tested dosing exists, and we do not recommend taking it internally.If you come across a product that contains groundsel, do not assume any amount is safe.

About Cefepime Injection

What Is Cefepime Injection Used For?

Brand name: Maxipime

Cefepime injection is used to treat a range of serious bacterial infections in adults and children. These include moderate-to-severe pneumonia, uncomplicated and complicated urinary tract infections (including pyelonephritis, a kidney infection), uncomplicated skin and skin structure infections, and empiric therapy (treatment started before a specific germ is confirmed) for fever in patients with very low white blood cell counts (febrile neutropenia).

In adults, cefepime injection is also used to treat complicated intra-abdominal infections — but only when given together with another antibiotic called metronidazole. The intramuscular (IM) route is indicated only for mild-to-moderate uncomplicated or complicated urinary tract infections caused by E. coli.

Taking Groundsel and Cefepime Together: Common Questions

Is it safe to take Groundsel with Cefepime?
We do not list a known interaction between Groundsel and Cefepime. 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 Groundsel and Cefepime have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
How was the Groundsel and Cefepime combination checked?
Interactions in our licensed database are recorded against drug classes. Cefepime is filed under 5 classifications, and Groundsel has documented interactions with 1 drug class — none of Cefepime'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 Groundsel interact with any other medications?
Yes. Groundsel has 87 documented drug interactions in our database — Cefepime 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 Cefepime interact with any supplements?
Yes. Cefepime has documented interactions with 43 supplements in our database — Groundsel is not one of them. The Cefepime interaction page linked on this page lists every one, ranked by severity.
