The bottom line No known interaction

We found no known interaction between Myrcia and Moxifloxacin 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.

Myrcia and Moxifloxacin

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 Moxifloxacin and Myrcia 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 Moxifloxacin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Moxifloxacin is filed under 9 classifications — including quinolone antibiotics, organic anion-transporting polypeptide substrates (oatp), qt interval-prolonging drugs. Myrcia has documented interactions with 1 drug class — the most serious being levothyroxine (synthroid, others) (moderate) — and none of Moxifloxacin’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.

From our pharmacist’s overview on the Moxifloxacin page

“The supplement list for moxifloxacin (Avelox), a fluoroquinolone antibiotic, deserves genuine care, and the everyday items are the surprising part. Ordinary juices, apple, grapefruit, and sweet orange among them, block a transporter the drug needs for absorption and can cut how much reaches your blood, which for an antibiotic means the…”

About Myrcia

What is Myrcia?

  • Blood sugar support
  • Digestive upset and diarrhea
  • Mild urinary complaints
  • Astringent for the gut
  • Traditional 'pedra-hume-caa' folk remedy

Myrcia is a group of tropical shrubs and trees in the myrtle family, used in South American folk medicine—often as a tea—mainly for blood sugar and digestive complaints. Human evidence is very limited, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you have diabetes or take other medicines.

Myrtaceae · Leaves (and sometimes bark) · Tea, dried leaf, capsules, liquid extracts

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

Myrcia: dosing

There is no established standardized dose for Myrcia. Traditional use is usually as a tea made from the dried leaves, but amounts vary widely and are not backed by clinical research.If you choose to try a commercial product, follow the directions on the label and do not exceed them.

About Moxifloxacin

What Is Moxifloxacin Used For?

Moxifloxacin tablets and intravenous (IV) injection are approved for adults 18 and older to treat bacterial infections including community-acquired pneumonia, uncomplicated and complicated skin infections, complicated abdominal infections, plague, acute bacterial sinusitis, and acute bacterial flare-ups of chronic bronchitis. Note: moxifloxacin should only be used for sinusitis and chronic bronchitis flare-ups when no other antibiotic option is available, due to the risk of serious side effects.

Moxifloxacin ophthalmic solution (eye drops) — including the brand Vigamox — is a separate, topical formulation used only in the eye to treat bacterial conjunctivitis (pink eye) caused by susceptible bacteria. The eye drop form is not used for body-wide infections.
