Flagyl monotherapy is the most effective treatment for many bacterial infections (including severe ones). The drug is also effective in cases where other antibiotics turn ineffective for the treatment of the infection.
Despite the pronounced antimicrobial effect, Flagyl is well tolerated and rarely causes side effects. The drug completely kills the pathogenic microflora that causes infectious or inflammatory processes.
- Brand Name: Flagyl;
- Active Ingredient: Metronidazole;
- Manufacturer: Sanofi.
Flagyl and its active substance Metronidazole
Flagyl tablets contain the drug substance Metronidazole, which has antimicrobial and antiprotozoal effects. This is an approved synthetic antibiotic for general (systematic) use:
- It has an effect on infections caused by certain types of unicellular organisms (protozoa);
- It has anti-inflammatory properties;
- It stops growth or kills certain types of bacteria that live without oxygen (anaerobic bacteria).
The active ingredient has a high penetrating power for most biological tissues and fluids of different parts of the body.
The maximum bactericidal concentration of Metronidazole is reached within 3 hours in:
- Cerebrospinal fluid;
- Secretion of the glands of the cervical mucosa;
- Secretion of the salivary glands;
- Seminal plasma;
- Internal organs (including lungs, liver and kidneys).
The half-life is up to about 11.5 hours, even in the presence of renal insufficiency. Considering the pharmacokinetic properties, Flagyl is prescribed as a single dose, or up to 3 doses per day.
Indications for use
Primarily, Flagyl is indicated for infections caused by anaerobic microorganisms. The drug is very effective for this type of pathogens, unlike other types of antibacterial agents.
Flagyl is prescribed for treatment of a wide range of infections, including:
- Reproductive system (for example, giardiasis, bacterial vaginosis);
- Gastrointestinal (for example, diarrhea, abdominal infection);
- Other parts of the body (skin, internal organs, blood, and nervous system).
In some cases, this antimicrobial drug is used for the treatment of inflammatory diseases of the perianal area and prevention of infections, for example, before orthopedic and trauma surgeries.
Treatment regimens and dosages
IMPORTANT INFORMATION! The dose is determined by a doctor, who adjusts it individually for you. The dosage depends on the type of infection, the severity of the disease, the presence of contraindications and other conditions.
A typical dosage regimen for the treatment of bacterial infections:
- A usual starting dose is 800 mg;
- Subsequent doses are 400 mg three times a day at regular intervals;
- Depending on the indications, you may be prescribed standard doses ranging from 200 mg to 800 mg up to three times a day.
Even after a few days of treatment, the symptoms may disappear. However, it is very important that a Flagyl treatment (usually 7 days) is completed according to the recommendations. Otherwise, there is a high chance that the infection comes back.
The duration of treatment can be extended by 3 days. The treatment of diseases related with changes in the microflora of the vagina my sometimes require a one-day treatment with the use of a single 2000 mg dose.
Children may be prescribed small doses of Flagyl up to four times a day. Doses for children, including those under 1 year of age, are calculated based on body weight (from 15 mg to 50 mg/kg/24 hours).
Recommendations for use
Follow these guidelines and tips:
- Take the tablets daily, preferably at the same time;
- Take the tablets before or after meals;
- Take the tablets whole with a full glass of water;
- If you still have signs of an infection after you finish your Flagyl treatment, call your doctor.
If you miss one or more doses, this may reduce the treatment effectiveness. Take the missed dose as soon as you remember. Skip a dose if it's almost time for the next dose.
Don't take Flagyl if you are hypersensitive to:
- Any medicine containing Metronidazole (active ingredient of Flagyl);
- Any medication of the nitroimidazole family.
You should be careful with this drug if you have progressive, chronic, or severe diseases of the central or peripheral nervous system (for example, neuropathy).
Use of Flagyl during pregnancy
Don't take Flagyl if you are planning to get pregnant, are pregnant or breastfeeding, unless advised otherwise by a doctor.
Possible side effects

- Cramps (pain) in the abdomen;

Metronidazole: interaction with other drugs

No problems! The drug worked!
Flagyl got rid of discharge, odor, etc. but I had hangover-like headaches! As a whole, I'm satisfied.
I didn't have any of the side effects that everyone talks about so much.
I took the drug in the summer of 2018, and in January 2022 I was again diagnosed with the same bacterial infection. Flagyl works almost immediately, but I feel like I'm on autopilot. I had a slight dizziness and occasional bloating, but that's about it.
Gradually, I see improvements. In the morning I notice dark urine, it turns out this is a rare side effect. If the antibiotic works as before, I'm willing to bear this temporary discomfort.
Bought Flagyl 200 mg tablets I couldn't find in other online pharmacies
Hello to everyone. I'm the most sensitive guy when it comes to antibiotics. I took a lot of Flagyl (2400 mg per day) and NOTHING BAD HAPPENED! My recommendations: don't drink alcohol, cut out sugar and follow all directions.
I ordered 2 packages of Flagyl. It is a very good pharmacy, the staff is pleasant, it can't be better
I was prescribed Flagyl instead of an antibiotic which didn't seem to work. I woke up at night with a very bitter taste in my mouth. I had to get out of bed and rinse my mouth to get rid of it, but the fast drug effects were worth it. I had a minor infection, and visible infection was resolved within 48 hours
Good price and fast delivery, recommend!
Just so you know. Although I’m not really a drinker, I took a few sips of alcohol 1 day after taking Flagyl. Face redness with severe nausea was very unpleasant.
I crossed fingers and bought Flagyl online. I worried about the side effects, but it turned out to be in vain. A 10-day treatment ended on Saturday, and my infection was eliminated.
I know it's a strong antibiotic. It can help you, friends.
I took a 200 mg dose three times a day for dental surgery! I didn't pay much attention to the side effects because I saw that Flagyl worked.
I went to the doctors distressed and desperate for help. I felt completely at a loss and thought that no treatment would help. I had bacterial vaginosis with worsening symptoms. By the second day of using Flagyl, I had brain fog and strong fatigue, but the “fishy” smell began to weaken. The side effects were unpleasant, but not too disturbing. I believe it's just the price to pay for recovery.
I feel much better than when I had an infection. I had to take Flagyl 400 mg 2 times a day for 1 week to get rid of trichomoniasis. I read on the Internet that sometimes trichomoniasis comes back a few months after treatment, and fingers crossed this is not my case.
I take Flagyl from time to time. Great for many infections
100% recovery. After 3 days, the symptoms disappeared, but I continued the therapy for another 4 days.
I'm 27. I had a fever and other symptoms due to bacterial vaginosis, I had never experienced anything like this before. I went to a doctor all-panicking. If you have experienced this, you know how much it can affect your self-confidence. I have been using Flagyl and vaginal gel for 5 days now. My infection seems to be gone, no smell and no watery discharge. 2 days left, and all in all, I feel well.
I'm taking this drug for the second time, I'm very glad that the infection is eliminated fast enough. During the treatment I constantly had a strange dizziness, but either way, Flagyl works great.
The price of Flagyl is great, much cheaper than in other pharmacies.
Over the past 3 months, I had sex only once, but that was enough to get bacterial vaginosis. Since then I haven't had sex but had a disgusting constant discharge and bad smell, I felt so lost and hopeless. My gynecologist told me to use Flagyl, I have been taking this medicine for five days and I feel sick. But I immediately noticed how effective it is. My body is working hard to fight infection. I decided to just try to relax and not worry about trifles.
I had giardiasis and felt terribly depressed. Abdominal pain is far from the worst symptom I've had. Doctor prescribed Flagyl 500 mg twice a day for one week. My side effects (drowsiness and headaches) are not that bad compared to intestinal upset.
I have been prescribed to take 200 mg 3 times a day for 10 days, and it's now the 6th day of treatment. This is the best medicine I have ever taken in my life. My nasty infection is in a downward phase, the pills didn't make me feel bad at all.
After three days of taking Flagyl, urethritis was reduced by nearly 95 %. Everything else, including joint pain and loss of appetite, persists, but it's worth it for the burning sensation during urinating to disappear.
I'm using this drug for the second time. The last time everything was resolved quickly for me, but after six months the problem came back. I hope this time the problem will be eliminated once and for all and I won't have to take antibiotics again.
Ordering was easy and convenient. Flagyl tablets were delivered as fast as I expected.
I took this drug for three days. At once, I had pains in the stomach and for some reason in the joints. And this afternoon I suddenly realized that there is no pain, and the burning sensation during urination disappeared. Need to use it for 2 more days.
My advice: do not use alcohol, drink plenty of water, go through the entire course of treatment, and know this will end soon!
