Drug & supplement interaction

Perilla + 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 Perilla 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.

Interaction report

Perilla 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 Perilla 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 Perilla at all — not against Cefepime, 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 Perilla 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. One of them is worth acting on rather than waiting out — marked below.

    “Orally, many cases of anaphylaxis have been reported in adults and children who consumed perilla seeds. Some research suggests that oleosin is the major constituent responsible for perilla allergies.”

Everything else you take

See Every Supplement That Interacts With Cefepime

This page covers Perilla 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 Perilla

What is Perilla?

Perilla
  • Seasonal and food allergies
  • Asthma and airway inflammation
  • Atopic dermatitis (eczema)
  • Digestive upset
  • General anti-inflammatory support

Perilla is an Asian mint-family plant used in cooking and traditional medicine, mainly for allergy, breathing, and digestive complaints. Most human evidence is limited or preliminary, so it should not replace proven treatments. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using concentrated supplements.

Perilla frutescens · Lamiaceae · Leaves, seeds, stem, and seed oil · Tea, capsules, seed oil, essential oil, dried leaf, culinary herb

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

Perilla: dosing

There is no well-established standard dose for perilla supplements. Products vary widely in their form and strength, from leaf teas to seed oil softgels to standardized extracts.The safest approach is to follow the directions on the product label and not to exceed them.

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 Perilla and Cefepime Together: Common Questions

Is it safe to take Perilla with Cefepime?
We do not list a known interaction between Perilla 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 Perilla 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.
Does Cefepime interact with any supplements?
Yes. Cefepime has documented interactions with 43 supplements in our database — Perilla is not one of them. The Cefepime interaction page linked on this page lists every one, ranked by severity.
