Patient summary
Metronidazole 200mg and 400mg tablets, used for bacterial infection, protozoal infection and bacterial vaginosis. A nitroimidazole taken by mouth.
Mechanism of action
Metronidazole is a nitroimidazole derivative that disrupts bacterial and protozoal metabolic processes. Once inside the cell, it is reduced, creating intermediates that damage DNA, thereby inhibiting nucleic acid synthesis and causing cell death.
Pregnancy and breastfeeding
Pregnancy: Avoid during the first trimester. Breastfeeding: Suspend breastfeeding during treatment.
Flagyl is a treatment by Sanofi containing the active ingredient metronidazole, used for bacterial infection, protozoal infection and bacterial vaginosis. Supplied as a tablet in strengths of 200mg and 400mg, this medication is a common option for managing these concerns.
Buying Flagyl online
Generic metronidazole, much of it made in India, is far more affordable than the original brand, offering an accessible route to treatment for expats and people living far from established medical support. This medication is best used under a doctor’s care.
Is Flagyl from SGMeds the original brand?
No. SGMeds ships a generic with the same active ingredient (metronidazole) at the strength you choose, not the original Flagyl made by Sanofi. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
What is Flagyl for?
Flagyl is used for bacterial infections, protozoal infection and bacterial vaginosis.
How much does Flagyl cost in Singapore?
Flagyl comes in 200 and 400mg strengths, in packs of 30 to 360 tablets. Each option's price is shown on this page in Singapore dollars, converted from US dollars, so the exchange rate can change the final amount. Larger packs work out cheaper per tablet.
Payment and prices →Can Flagyl cause side effects?
Yes. The most common side effects of metronidazole are nausea, metallic taste and headache. Less common ones are darkened urine and diarrhoea. Serious side effects include nerve damage in the hands or feet (peripheral neuropathy) and seizures. Get medical help straight away if you notice one of these serious effects.
Can I drink alcohol while taking Flagyl?
Metronidazole interacts with alcohol, so it is best to avoid drinking while you take Flagyl. Ask a doctor or pharmacist how long to wait before drinking again.
Which medicines interact with Flagyl?
Metronidazole can interact with warfarin and disulfiram. Before you start Flagyl, tell your doctor or pharmacist about any medicines, supplements or herbal remedies you take.
Can I order Flagyl without a prescription?
Yes. SGMeds does not ask for a prescription to order Flagyl: we place the order with our pharmacy partner, which prepares it and arranges delivery on your behalf.
Ordering without a prescription →Can I buy Flagyl online in Singapore?
Yes, here on SGMeds: choose the strength and pack, then check out. Parcels go to Singapore and Malaysia by Express shipping (tracked, up to 1 week) or Regular shipping (up to 3 weeks).
How ordering works →What you will receive
Flagyl is the originator brand name, made by Sanofi. We use it here to identify the medicine only; we are not affiliated with Sanofi and do not ship the original Flagyl.
- You receive a generic equivalent: the same active ingredient (Metronidazole) at the same dose, mostly recognised Indian branded generics from vetted manufacturers.
- The exact brand supplied depends on what is in stock at the dispatching warehouse.
- A regulated generic matches the original ingredient for ingredient by legal standard.
