Metronidazole: Uses, Side Effects & Interactions
When working with metronidazole, a nitroimidazole antibiotic that targets anaerobic bacteria and certain parasites. Also known as Flagyl, it is prescribed for infections like bacterial vaginosis, dental abscesses, and giardiasis. Antibiotic, a drug class designed to kill or inhibit bacterial growth. Antimicrobial therapy relies on proper dosing and awareness of drug interaction, a chemical or physiological response that alters a medication’s effect when combined with another substance. Medication interaction. Understanding these pieces lets you use metronidazole safely and effectively.
Key Relationships and Practical Details
Metronidazole belongs to the nitroimidazole family, which means its bacterial action depends on low‑oxygen environments. Metronidazole therefore encompasses the treatment of anaerobic infection, an infection caused by bacteria that thrive without oxygen. Obligate anaerobe infection. This connection explains why the drug is effective for pelvic inflammatory disease, intra‑abdominal abscesses, and severe gum disease. Side effects such as nausea, metallic taste, and rare neurological symptoms are linked to the way the drug is metabolized in the liver. Because metronidazole can inhibit the enzyme CYP2C9, it may increase blood levels of drugs like warfarin, leading to heightened bleeding risk. The interaction requirement is clear: patients on anticoagulants need closer monitoring, and alcohol should be avoided to prevent a disulfiram‑like reaction.
