What Is Metrogyl 200mg?
Metrogyl 200mg is a prescription antibiotic widely used across Australia to treat bacterial and protozoal infections. It contains Metronidazole, a long-standing and dependable antimicrobial medication known for treating infections that thrive in places without oxygen (anaerobic bacteria).
Doctors regularly prescribe Metrogyl 200mg for:
- Bacterial Vaginosis (BV)
- Trichomoniasis (a sexually transmitted infection)
- Giardiasis and Amoebiasis (gut infections from contaminated food or water)
- Dental and gum infections
- Post-surgical infections involving internal organs
It’s part of the nitroimidazole class of antibiotics, which makes it different from the usual penicillin-based ones. It doesn’t just stop bacterial growth—it shuts down their ability to make and repair DNA, which kills the infection at its source.
You can find more official info about Metrogyl at the Therapeutic Goods Administration (TGA).
Why Australians Use Metrogyl 200mg
1. Effective Treatment for Common Infections
Metrogyl works quickly to reduce inflammation, discharge, and discomfort caused by bacterial vaginosis and trichomoniasis. It also prevents recurrence when both partners are treated correctly.
2. Reliable Alternative Antibiotic
Some people who can’t take penicillins find Metronidazole a safe and effective substitute.
3. Affordable and PBS Listed
It’s available under the Pharmaceutical Benefits Scheme, so most Australians pay between $7.30 and $30, depending on their eligibility.
4. Multi-purpose Use
Metrogyl isn’t just for gynaecological infections—it’s also used for infected wounds, gum abscesses, and certain stomach infections alongside other antibiotics such as amoxicillin.
If you’re taking Metrogyl for a dental or gum infection, pairing it with pain relievers from our Pain Relief section can help you get through those first few days of discomfort.
How to Take Metrogyl 200mg
Typical Dosage:
- Adults: One 200mg tablet, three times a day for 5–7 days.
- For BV or Trichomoniasis:Â Sometimes 400mg twice daily, or a single 2g dose.
- Always follow the exact instructions from your doctor. The dosage can differ depending on your infection type and response.
How to Take It Correctly:
- Swallow each tablet whole with a full glass of water.
- Take it with food to avoid nausea.
- Space your doses evenly throughout the day.
- Always complete your full course even if you feel fine halfway through – stopping early causes antibiotic resistance.
Important tip: Avoid alcohol during treatment and for 48 hours after finishing your last dose. Mixing alcohol with metronidazole can make you violently ill – you’ll get flushed, nauseous, vomit, and feel your heart racing.
If you’re also on other medications like Rantac 150mg or Corbis 5mg for stomach or heart conditions, make sure you tell your doctor so they can check for any interactions.

Side Effects – What to Expect
Most people handle Metrogyl 200mg pretty well. The common side effects tend to be mild and go away once treatment ends:
Common side effects:
- Nausea or metallic taste in the mouth
- Mild diarrhoea
- Loss of appetite
- Dark-looking urine (totally harmless)
Serious but rare side effects:
- Tingling or numb feeling in hands or feet
- Dizziness or seizures

If anything feels off or you experience numbness or allergic symptoms, stop the medication and contact your doctor immediately.
Avoid alcohol completely. That’s the big rule with Metronidazole. Even small amounts cause reactions.
Precautions Before Taking Metrogyl
Before taking this antibiotic, let your doctor know if you:
- Are pregnant or breastfeeding
