Calotropis + Plazomicin Sulfate

Plazomicin Sulfate brand name: Zemdri.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Calotropis and Plazomicin Sulfate 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

Calotropis and Plazomicin Sulfate

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 Plazomicin Sulfate and Calotropis 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 Plazomicin Sulfate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Plazomicin Sulfate is filed under 3 classifications — aminoglycoside antibiotics, antibiotic drugs, nephrotoxic drugs. Calotropis has documented interactions with 4 drug classes — the most serious being digoxin (lanoxin) (moderate), diuretic drugs (moderate) and lithium (moderate) — and none of Plazomicin Sulfate’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 Calotropis and Plazomicin Sulfate 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

    Calotropis

    “There is limited reliable information available about the safety of calotropis when taken as a medicine. Orally, high doses of calotropis have been reported to cause vomiting, diarrhea, bradycardia, convulsions, and death (18). Topical exposure to calotropis has been reported to cause contact allergies and corneal endothelial cell injury leading to edema and vision loss.”

Everything else you take

See Every Supplement That Interacts With Plazomicin Sulfate

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

“Plazomicin (Zemdri) is an IV antibiotic reserved for serious urinary tract infections, and like other aminoglycosides it can strain the kidneys all by itself. That is why the two major-rated entries on this list matter most: Siberian cocklebur and asarabacca can both harm the kidneys, and stacking either onto plazomicin could compound…”

About Calotropis

What is Calotropis?

  • Skin conditions and wounds (traditional, topical)
  • Joint pain and inflammation
  • Digestive complaints
  • Coughs and respiratory issues
  • Traditional Ayurvedic and folk remedies

Calotropis is a milkweed-family plant long used in traditional medicine, but its milky latex and other parts are potentially toxic and can harm the eyes, skin, and heart. Human evidence for any health benefit is very limited, and the risk of poisoning is real, so it should not be taken internally without expert medical supervision.

Calotropis procera · Apocynaceae · Latex (milky sap), leaves, roots, and flowers · Traditional preparations such as dried plant powder, root or leaf extracts, and topical applications of latex; rarely standardized commercial products

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

Calotropis: dosing

There is no established safe or standardized dose of Calotropis. In general, internal use is best avoided.

About Plazomicin Injection

What Is Plazomicin Injection Used For?

Taking Calotropis and Plazomicin Sulfate Together: Common Questions

Is it safe to take Calotropis with Plazomicin Sulfate?
We do not list a known interaction between Calotropis and Plazomicin Sulfate. 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 Calotropis and Plazomicin Sulfate 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 Calotropis and Plazomicin Sulfate combination checked?
Interactions in our licensed database are recorded against drug classes. Plazomicin Sulfate is filed under 3 classifications, and Calotropis has documented interactions with 4 drug classes — none of Plazomicin Sulfate'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 Calotropis interact with any other medications?
Yes. Calotropis has 98 documented drug interactions in our database — Plazomicin Sulfate 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 Plazomicin Sulfate interact with any supplements?
Yes. Plazomicin Sulfate has documented interactions with 35 supplements in our database — Calotropis is not one of them. The Plazomicin Sulfate interaction page linked on this page lists every one, ranked by severity.
