Metronidazole uses?

Metronidazole is an antibiotic/antiprotozoal that works mainly against anaerobic bacteria and certain parasites. Common uses include:

- Protozoal infections:
- Giardia lamblia (giardiasis)
- Entamoeba histolytica (amebiasis, including intestinal amebiasis and amebic liver abscess)
- Trichomonas vaginalis (trichomoniasis)

- Bacterial (mostly anaerobic) infections:
- Intra-abdominal infections (e.g., peritonitis, abscesses)
- Gynecologic infections (e.g., pelvic inflammatory disease, endometritis, tubo-ovarian abscess, postpartum endometritis)
- Respiratory infections with anaerobic coverage (e.g., aspiration pneumonia)
- Polymicrobial or abscess-associated infections

- Helicobacter pylori eradication regimens (as part of combination therapy with a PPI and another antibiotic, in certain regimens for peptic ulcers)

- Skin and mucosal infections (topical use):
- Rosacea (topical metronidazole)
- Bacterial vaginosis and, in some cases, trichomoniasis (oral or vaginal forms)

- Other uses (often in combination with other agents):
- Certain dental/oral infections with anaerobic bacteria
- Brain abscess due to anaerobes (often in combination with other antibiotics)

If you’re asking about a specific condition or want typical dosing regimens, tell me the scenario and I can summarize the appropriate use and doses.
