Myrtle + nitazoxanide
nitazoxanide brand name: Alinia.
We found no known interaction between Myrtle and nitazoxanide 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 label for nitazoxanide states a food rule worth keeping to.
Myrtle and nitazoxanide
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 nitazoxanide and Myrtle 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 Myrtle at all — not against nitazoxanide, 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.

Some nitazoxanide Products Have a Food Rule — Myrtle Should Not Break It
At least one FDA label for a product containing nitazoxanide says to take it with food. If you take Myrtle on an empty stomach out of habit, keep them separate — and take nitazoxanide with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two nitazoxanide products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
What nitazoxanide Is Prescribed For, and What Myrtle Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. nitazoxanide is a prescription medicine with approved uses on its FDA label. Myrtle is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
nitazoxanide is prescribed for: Nitazoxanide tablets (for patients 12 years and older) treat diarrhea caused by two parasites: Giardia lamblia and Cryptosporidium parvum. These are intestinal parasites that can cause significant diarrhea and digestive upset. Important limitation: nitazoxanide tablets and Alinia for oral suspension have not been shown to work for diarrhea caused by Cryptosporidium parvum in people who are HIV-positive or have a weakened immune system.

Diarrhea studied, not established Myrtle has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Myrtle for diarrhea
Although there has been interest in using oral myrtle for diarrhea, there is insufficient reliable information about the clinical effects of myrtle for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace nitazoxanide on your own; if you are taking Myrtle for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the nitazoxanide page
“Nitazoxanide (Alinia) is an antiparasitic taken as a short course, often just three days, to clear gut infections like giardiasis, so every dose needs to actually reach the bloodstream. That is exactly what the 17 supplements on this page can undermine, and it is why this list deserves real care rather than a shrug.”

About Myrtle
What is Myrtle?
- Coughs and respiratory congestion
- Digestive upset
- Antimicrobial and wound care
- Skin conditions
- Urinary complaints
Myrtle (Myrtus communis) is a Mediterranean shrub used traditionally for respiratory, digestive, and skin complaints. Modern research is mostly limited to laboratory and small studies, so its benefits in people are not well proven. Use cautiously, follow product labels, and talk to your pharmacist or doctor first—especially since the essential oil should never be swallowed.
Myrtus communis · Myrtaceae · Leaves, berries, flowers, and essential oil · Tea, capsules, extracts, essential oil, topical preparations
An interaction check asks whether these two react with each other — it does not ask whether Myrtle is a good idea for someone in your situation. Here is what our Myrtle record says about it on its own.
Myrtle: dosing
There is no well-established standard dose for myrtle. Amounts used in traditional practice and studies vary widely depending on the form—tea, extract, capsule, or oil.Because products differ in strength and quality, the safest approach is to follow the directions on the product label and not exceed them.
