Is metronidazole flagyl?

Yes. Flagyl is a brand-name (one of several) for metronidazole.

Key points:
- Metronidazole is an antibiotic/antiprotozoal used for certain anaerobic bacterial infections and protozoal infections (e.g., bacterial vaginosis, trichomoniasis, giardiasis, amebiasis, some intra-abdominal and gynecologic infections).
- It comes in oral, topical, and IV forms. Dosing and duration vary by infection.
- Do not drink alcohol during treatment and for about 48 hours (some guidance says up to 72 hours) after finishing.
- Common side effects: nausea, stomach upset, metallic taste, headache. Rare serious reactions can occur.
- Interactions: may interact with alcohol, and with anticoagulants like warfarin; talk to your clinician about any other medications.
- Pregnancy/breastfeeding: consult a healthcare provider.

If you have a specific infection or prescription, I can help interpret the dosing or common side effects for that use.
