The bottom line No known interaction

We found no known interaction between Schizonepeta and Gentamicin (IV) 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.

Schizonepeta and Gentamicin (IV)

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 Gentamicin (IV) and Schizonepeta 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.

Schizonepeta safety at a glance

Schizonepeta overall Use caution Generally used in small amounts in traditional formulas, but high-quality safety data in humans are limited.
Pregnancy Avoid Safety in pregnancy has not been established, so it is best avoided.
Breastfeeding Avoid There is not enough information to consider it safe while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Gentamicin (IV)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gentamicin (IV) is filed under 3 classifications — aminoglycoside antibiotics, antibiotic drugs, nephrotoxic drugs. Schizonepeta has documented interactions with 4 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2d6 (cyp2d6) substrates (moderate) and cytochrome p450 2e1 (cyp2e1) substrates (moderate) — and none of Gentamicin (IV)’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

What Schizonepeta Itself Has Been Linked To

This is not an interaction — nothing below involves Gentamicin (IV). It is the side-effect record for Schizonepeta on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Schizonepeta, this list is the first place to look.

  • Hair loss Additional detail

    “There is currently a limited amount of information available about the adverse effects of schizonepeta. Orally, a specific combination product (Zemaphyte, Phytopharm Plc) containing schizonepeta and numerous other ingredients has been reported to cause nausea, vomiting, colic, dyspepsia, dizziness, headache, and hair loss.”

  • Stomach upset / Vomiting / Nausea Additional detail

    “Orally, a specific combination product (Zemaphyte, Phytopharm Plc) containing schizonepeta and numerous other ingredients has been reported to cause nausea, vomiting, colic, and dyspepsia. However, it is unclear if these effects are due to schizonepeta or the other ingredients.”

Everything above comes from the Natural Medicines adverse-effect record for Schizonepeta — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Gentamicin (IV)’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Gentamicin (IV) column appears here.

Everything else you take

See Every Supplement That Interacts With Gentamicin (IV)

This page covers Schizonepeta only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Gentamicin (IV) page lists 35 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 · 31 moderate · 2 minor.

From our pharmacist’s overview on the Gentamicin (IV) page

“Kidney protection is the reason this list deserves real attention. Gentamicin (Garamycin) is an IV antibiotic that can stress the kidneys on its own, and both of the major-rated entries among the 35 supplements on file share that same weakness.”

About Schizonepeta

What is Schizonepeta?

  • Common cold and early-stage fever
  • Itchy skin rashes and hives
  • Sore throat
  • Headache
  • Measles and other skin eruptions (traditional use)

Schizonepeta is a mint-family herb long used in traditional Chinese medicine, usually as part of combination formulas for colds, fevers, and itchy skin conditions. Modern human evidence is very limited, so its benefits are not well proven. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Schizonepeta tenuifolia · Lamiaceae · Dried aerial parts (stems and flower spikes); sometimes the essential oil · Dried herb for decoctions (tea), powders, capsules, and as part of traditional herbal formulas

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

Schizonepeta: dosing

There is no well-established standardized dose for Schizonepeta. In traditional Chinese medicine it is typically used as a dried herb in a decoction, often combined with other herbs, and amounts are tailored by a trained practitioner.For commercial supplements, follow the directions on the product label.

About Gentamicin Topical

What Is Gentamicin Topical Used For?

Brand name: Garamycin

Gentamicin sulfate topical is used to treat primary skin infections — infections that start directly in the skin — such as impetigo contagiosa, superficial folliculitis (infected hair follicles), furunculosis (boils), ecthyma, sycosis barbae, and pyoderma gangrenosum.

It also treats secondary skin infections, where bacteria have moved into already-irritated or damaged skin. This includes infected eczema, infected contact dermatitis (like poison ivy that gets infected), pustular acne, pustular psoriasis, infected seborrheic dermatitis, and bacterial infections on top of fungal or viral skin conditions. It has also been used successfully for infected stasis ulcers, infected superficial burns, infected insect bites and stings, infected lacerations and abrasions, paronychia (infected nail folds), and wounds from minor surgery.
