Pharmacological effect
An antibacterial drug has a special mechanism of action, which is to activate the biochemical reduction of the fifth nitro group using intracellular transport proteins of the simplest and anaerobic mechanisms, as described in the instructions for use. Recovered cells interact with the DNA of microorganisms, which is accompanied by inhibition of the synthesis of their nucleic acid. As a result, the immediate death of bacteria occurs.
The instruction of the antibacterial tablet preparation contains information that it is effective against gram-negative and some positive anaerobes. The minimum inhibitory concentration for the destruction of pathogenic microorganisms is the dose of 0.125-6.25 µg / ml. The antibiotic, together with amoxicillin, is active against Helicobacter pylori, since such a combination of drugs contributes to the suppression of the development of resistance.
The drug "Metronidazole" is not active against aerobic microorganisms and facultative forms of anaerobes. It should be noted that in the presence of mixed flora, this drug acts synergistically with antibacterial agents that are effective against simple aerobes. Metronidazole affects tumors by increasing their sensitivity to radiation. The drug has a disulfiram-like effect, causing sensitization to alcohol, and also turns out to be a stimulator of reparative processes.

On the part of the urogenital system can be cystitis, candidiasis, urinary incontinence, urine staining.
On the skin can be observed urticaria, itching, hyperemia.

special instructions
Before you start using the drug, read the specific instructions:
It paints urine in a dark color.
In combination with amoxicillin is not recommended for use in patients younger than 18 years.
With prolonged therapy, it is necessary to control the blood picture.
In case of leukopenia, the possibility of continuing treatment depends on the risk of developing an infectious process.
The appearance of ataxia, dizziness, and any other deterioration in the neurological status of patients requires discontinuation of treatment.
It can immobilize treponema and lead to a false-positive Nelson test.
When treating Trichomonas vaginitis in women and Trichomonas urethritis in men, it is necessary to abstain from sex. Necessarily simultaneous treatment of sexual partners. The treatment does not stop during menstruation. After treatment of trichomoniasis, control tests should be carried out for three consecutive cycles before and after menstruation.
After giardiasis treatment, if symptoms persist, after 3–4 weeks to perform 3 feces analyzes at intervals of several days (in some successfully treated patients, lactose intolerance caused by invasion may persist for several weeks or months, resembling giardiasis symptoms).
Compatibility with alcohol
During the treatment period, ethanol use is contraindicated (a disulfiram-like reaction may develop: spastic abdominal pain, nausea, vomiting, headache, a sudden rush of blood to the face).
Drug interactions
When using the drug, you must consider the interaction with other drugs:
Sulfonamides enhance the antimicrobial action of metronidazole.
It enhances the effect of indirect anticoagulants, which leads to an increase in the time of formation of prothrombin.
Similar to disulfiram, it causes intolerance to ethanol.
When taken simultaneously with lithium preparations, the concentration of the latter in plasma and the development of symptoms of intoxication may increase.
It is not recommended to combine with non-depolarizing muscle relaxants (vecuronium bromide).
Cimetidine inhibits the metabolism of metronidazole, which can lead to an increase in its concentration in serum and an increase in the risk of side effects.
The simultaneous administration of drugs that stimulate microsomal oxidation enzymes in the liver (phenobarbital, phenytoin) can accelerate the elimination of metronidazole, as a result of which its concentration in plasma decreases.
Simultaneous use with disulfiram can lead to the development of various neurological symptoms (the interval between administration is at least 2 weeks).
Reviews
We picked up some reviews of people taking Metronidazole:
Catherine
Saw it 2 tablets in the morning and evening with doxycycline for 7 days. At first, I didn’t understand what makes me dizzy, noisy, I’m wobbling and nauseous. I read about side-horror, half of them I just collected. I hope he really helps and I was not in vain.
Helena
For all who have noticed the side effects of drug treatment: keep in mind that such symptoms can be caused by intoxication by decay Giardia, which die from metronidazole, maybe you just have a chronic latent giardiasis ...
Karina
I used metronidazole for severe acne, I prescribed his doctor a cosmetologist, I liked the effect, the acne was much less. That's just a little nauseous after taking, and then nausea passed somehow herself.
Tatyana
For me, metronidazole is a lifeline. It is always in my purse. Like many women, I often suffer from cystitis. It happens that this ailment takes by surprise at work. In this case, I have metronidazole, and I know that it will definitely help. This is an old proven tool that was used by my mother. It is an antimicrobial and anti-inflammatory drug. Tablets of round color, with easy yellowness. It tastes very bitter, and this is the only negative for me. When exacerbation of cystitis helps me within 20 minutes after taking. The only thing I would like to say is that, like any effective antimicrobial medicine, metronidazole also kills the beneficial microflora, therefore, so that there are no problems with the intestines, it is advisable to drink bifidobacteria after taking it.
