Source-derived summary

Metronidazole, sold under the brand name Flagyl and Metrogyl among others, is an antibiotic and antiprotozoal medication. It is used either alone or with other antibiotics to treat pelvic inflammatory disease, endocarditis, and bacterial vaginosis. It is effective for dracunculiasis, giardiasis, trichomoniasis, and amebiasis. It is an option for a first episode of mild-to-moderate Clostridioides difficile colitis if vancomycin or fidaxomicin is unavailable. Metronidazole is available orally (by mouth), as a cream or gel, and by slow intravenous infusion (injection into a vein).

Common side effects include nausea, a metallic taste, loss of appetite, and headaches. Occasionally seizures or allergies to the medication may occur.

Metronidazole began to be commercially used in 1960 in France. It is on the World Health Organization's List of Essential Medicines. It is available in most areas of the world.

Editorial summary

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1960—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Metronidazole, chemical and compound.
Editorial analysis

Why this record matters

“Metronidazole” is worth following because a concise public description often conceals a longer documentary argument. Here, Metronidazole, chemical and compound provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q169569. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1960.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
