Flagyl (Metronidazole) Buyer and Patient Handbook in Singapore
What is Flagyl?
Flagyl (Metronidazole) is a nitro-imidazole antibiotic used to treat infections caused by anaerobic bacteria and certain parasites. It belongs to the nitroimidazole class and is commonly prescribed for Bacterial Vaginosis, Trichomoniasis, amoebic dysentery, and intra-abdominal infections. Flagyl is approved by the FDA, EMA and the Health Sciences Authority (HSA) of Singapore and is available as oral pill tablets in 200 mg and 400 mg strengths.
Who Should Use Flagyl?
- Adults (≥18 years) with confirmed anaerobic or protozoal infection.
- Adolescents when benefits outweigh risks, as judged by a qualified clinician.
- Patients who are not pregnant or are in the second/third trimester (first trimester requires specialist assessment).
How Does It Work?
Flagyl penetrates bacterial cells and, under low-oxygen conditions, its nitro group is reduced to reactive metabolites that disrupt DNA synthesis and cause strand breakage, leading to bacterial death. Think of it as a “molecular sabotage” that stops the microbe’s engine from running. It has no abuse potential and is not habit-forming.
Why Choose Flagyl?
- Broad spectrum against anaerobes and protozoa makes it a first-line option for many mixed infections.
- Well-established safety profile with decades of clinical use.
- Generic versions are widely available, offering cost savings compared with brand-only alternatives.
(Off-label use should only be considered after discussing potential benefits and risks with a healthcare professional.)
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 200 mg tablet: 500 mg (two tablets) every 8 hours for most infections.
- 400 mg tablet: 400-800 mg every 8 hours depending on infection severity.
How to Take
- Swallow tablets whole with a full glass of water.
- Take with meals or a snack to minimise stomach upset.
Missed Dose
- If you remember within 2 hours, take the missed tablet.
- If it’s longer than 2 hours, skip and continue the regular schedule. Do not double-dose.
Overdose
- Seek immediate medical attention or contact the Singapore Poisons Centre (180-222-400).
- Symptoms may include Nausea, Vomiting, dizziness, or Seizures.
Special Populations
- Elderly: Dose may be reduced if renal or hepatic impairment is present.
- Children: Not routinely recommended; paediatric dosing requires specialist input.
- Renal/Hepatic disease: Adjust dose based on laboratory results; monitor liver enzymes.
Lifestyle & Diet
- Avoid alcohol during treatment and for 48 hours after the last dose to prevent a disulfiram-like reaction (flushing, nausea, palpitations).
- No significant food interactions, but grapefruit juice can increase plasma levels-limit consumption.
- Maintain adequate hydration; the drug is excreted renally.
Precautions and Warnings
- Pregnancy: Use only if clearly needed after first trimester.

Frequently Asked Questions
How long does a typical course of Flagyl last?
A standard course ranges from 5 to 10 days, depending on the infection type and severity.
Can I drink coffee while taking Flagyl?
Yes, moderate coffee consumption does not affect metronidazole’s effectiveness.
What should I do if I experience a metallic taste?
The taste usually resolves within a few days. Stay hydrated and rinse your mouth after each dose.
Is it safe to take Flagyl with over-the-counter pain relievers?
Acetaminophen is generally safe. NSAIDs (e.g., ibuprofen) can be used, but monitor for stomach irritation.
Why did my urine turn dark after starting Flagyl?
Metronidazole and its metabolites can temporarily darken urine; this is harmless and resolves after stopping the medication.
Can I stop taking Flagyl early if I feel better?
No. Completing the full prescribed course prevents recurrence and resistance.
Does Flagyl interact with antacids?
No clinically significant interaction has been reported.
What is the risk of developing antibiotic resistance with Flagyl?
Resistance is uncommon but possible with inappropriate or incomplete use; adhere strictly to the dosing schedule.

Reviews
Day 3 on this stuff. Doctor said it's for a stubborn gut infection. The main thing is this weird metallic taste in my mouth, like I'm sucking on old coins. It's constant. Also feeling a bit nauseous, but eating a small piece of ginger or some plain crackers before the pill helps a ton. Hoping it kicks in soon.
First time taking Flagyl, prescribed for BV. The nausea hit me hard about an hour after the first dose. I read online to absolutely avoid alcohol, so I'm being super careful. Even my mouthwash is alcohol-free now. It's a bit of a hassle, but I guess it's better than the alternative. Just want to finish this course.
I've had to take this a few times over the years for recurring diverticulitis. It works, no doubt. But the side effects are no joke. The key for me is taking it right in the middle of a meal, not just with food. A full plate of rice and something heavy. If I take it on an empty stomach, I'm down for the count with dizziness. And yeah, the no-alcohol rule is for real - learned that the hard way once.
Long-term user here for a chronic condition. The metallic taste never really goes away, you just get used to it. My hack: strong mints or sour candies help mask it. Also, I split my 400mg dose into two 200mg doses, morning and night, with my doctor's okay. Makes the nausea much more manageable. It's a necessary evil, but you learn to live with it.
This medication cleared up my dental infection incredibly fast. Like, within 48 hours the swelling was gone. But the trade-off was brutal fatigue. I felt like I could sleep for 12 hours straight. Drank a lot of water and tried to rest as much as possible. Worth it to get rid of the pain, but wouldn't want to be on it for a long time.
I take this occasionally for flare-ups. The biggest thing nobody tells you is about caffeine. I had my usual coffee one morning and felt jittery and anxious, like my heart was racing. Now I space it out - pill first, wait at least 3-4 hours before any coffee. Makes a huge difference. It's effective, but you have to be mindful of everything you consume.
It's complicated. Flagyl worked wonders for the intestinal infection it was prescribed for. However, it absolutely wrecked my gut microbiome. After the course, I had to deal with thrush and digestive issues for weeks. Had to load up on probiotics and yogurt. So it fixed one problem but created another. I'm glad I took it, but the aftermath was rough.
Prescribed for a parasite after a trip. The fatigue and loss of appetite were real. I forced myself to eat small, bland meals - congee was a lifesaver. Also, the pill itself is so bitter; if it even touches your tongue, it's awful. I learned to swallow it fast with a big gulp of juice or milk to cover the taste. Glad it's over.
