Drug & supplement interaction

Euphorbia Hirta + Itraconazole

Itraconazole brand names: Sporanox, Sporanox Injection, Tolsura.

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 Euphorbia Hirta and Itraconazole 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.

Euphorbia Hirta and Itraconazole

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 Itraconazole and Euphorbia Hirta 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 Euphorbia Hirta at all — not against Itraconazole, 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 Euphorbia Hirta and Itraconazole 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.

The most serious there right now: Activated Charcoal (major), Beer (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).

From our pharmacist’s overview on the Itraconazole page

“Serious fungal infections are what itraconazole (Sporanox, Tolsura) is for, and the drug travels through CYP3A4, the liver enzyme that also handles a large share of supplements. That overlap is why this list reaches 182 ingredients, and it earns genuine care; start with the six rated major.”

About Euphorbia Hirta

What is Euphorbia Hirta?

  • Respiratory complaints like asthma and cough
  • Diarrhea and digestive upset
  • Skin wounds and warts
  • Worms and other parasites
  • General antimicrobial use

Euphorbia hirta is a small tropical weed used in traditional medicine for breathing problems, diarrhea, and skin issues. Most of its supposed benefits come from laboratory or animal studies rather than solid human trials, so its true effectiveness in people is unclear. Because its safety is not well studied, talk to a pharmacist or doctor before using it.

Euphorbia hirta · Euphorbiaceae · Whole plant (leaves, stems, flowers, and latex) · Dried herb, tea/decoction, tincture, capsules, and topical extracts

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

Euphorbia Hirta: dosing

There is no standardized or well-established dose for Euphorbia hirta. Traditional preparations vary widely depending on the form (tea, juice, tincture, or capsule) and the region.Because product strength and purity can differ a lot between brands, follow the directions on the product label and do not exceed them.

About Itraconazole

What Is Itraconazole Used For?

Brand names: Sporanox, Sporanox Injection, Tolsura

Itraconazole capsules (including Sporanox capsules and generic itraconazole capsules) treat serious fungal infections — blastomycosis, histoplasmosis, and aspergillosis — in both people with normal immune systems and those who are immunocompromised. Capsule forms are also approved for nail fungus (onychomycosis) caused by dermatophytes in non-immunocompromised patients. Tolsura (a gelatin-coated capsule formulation) treats blastomycosis, histoplasmosis, and aspergillosis in adults, but is not approved for nail fungus and is not interchangeable with other itraconazole products.

Itraconazole oral solution is specifically approved for oropharyngeal candidiasis (thrush — a fungal infection of the mouth) and esophageal candidiasis (a fungal infection of the food pipe). Only the oral solution has been shown to work for these mouth and throat infections; capsules cannot be substituted for this use.

Most-Reported Side Effects for Itraconazole

From FAERS, the FDA’s public side-effect reporting system (11,613 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fever 590 reports
Dyspnea 489 reports
Pneumonia 484 reports

Taking Euphorbia Hirta and Itraconazole Together: Common Questions

Is it safe to take Euphorbia Hirta with Itraconazole?
We do not list a known interaction between Euphorbia Hirta and Itraconazole. 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 Euphorbia Hirta and Itraconazole 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.
Does Itraconazole interact with any supplements?
Yes. Itraconazole has documented interactions with 182 supplements in our database — Euphorbia Hirta is not one of them. The Itraconazole interaction page linked on this page lists every one, ranked by severity.
