Metronidasool is another-language name for metronidazole, a prescription medicine used to treat certain bacterial and parasitic infections. It is commonly known by its English medical name, metronidazole, and is available in several forms depending on the condition being treated.
People may search for Metronidasool after seeing the name on a prescription, medicine package, or health website in another language. Although it has several medical uses, it is not suitable for every infection.
This guide explains what Metronidasool is, how it works, what it treats, its different forms, possible benefits, common side effects, and important safety precautions.
What Is Metronidasool?
Metronidasool is another name for metronidazole. The spelling is used in Estonian and also appears in some Afrikaans-language medical information. Metronidazole is the standard English name for this prescription medicine.
It belongs to a group of medicines called nitroimidazoles. It has both antibacterial and antiprotozoal properties, meaning it can fight certain bacteria and single-celled parasites.
Metronidasool is particularly effective against certain anaerobic bacteria. These organisms can survive and grow in environments with little or no oxygen. This makes the medicine useful for specific infections affecting areas such as the abdomen, pelvis, and mouth.
Metronidazole is also sold under different brand names. Flagyl is one well-known example, although available brands vary from country to country.
It is important to understand that Metronidasool and metronidazole refer to the same active medicine. The difference is primarily the language used to describe it.
How Does Metronidasool Work?
Metronidasool works by entering bacteria and parasites that are sensitive to the medicine.
Once inside these organisms, the medicine is converted into active compounds. These compounds interfere with and damage the organisms’ genetic material, preventing them from surviving and multiplying.
This action helps the body clear infections caused by susceptible bacteria and parasites.
Metronidasool is especially useful against anaerobic bacteria, which can grow in areas with limited oxygen. This explains why healthcare professionals may prescribe it for certain infections involving the abdomen, pelvis, gums, or other parts of the body.
However, the medicine does not work against every type of microorganism. Some infections are caused by viruses or fungi, while others involve bacteria that are not sensitive to metronidazole.
A healthcare professional may need to perform tests, such as a blood test, stool test, or swab, to identify the cause of an infection before choosing the appropriate treatment.
What Is Metronidasool Used For?
Metronidasool has several established medical uses. The appropriate treatment depends on the type of infection, the organism responsible, and the part of the body affected.
Doctors may prescribe it for conditions such as:
- Bacterial vaginosis
- Trichomoniasis
- Amebiasis
- Amebic liver abscess
- Certain abdominal infections
- Some pelvic infections
- Specific anaerobic bacterial infections
- Certain gum infections and dental abscesses
- Rosacea when a suitable topical product is prescribed
Metronidasool may also be used alongside other antibiotics for complicated infections. This is particularly useful when several types of bacteria may be involved and one medicine alone may not provide sufficient coverage.
The medicine comes in different forms because each condition may require a different treatment approach. For example, certain skin conditions can be treated with a topical gel or cream, while some internal infections require tablets, liquid medicine, or intravenous treatment.
The correct form and treatment plan should always be based on a medical diagnosis rather than symptoms alone.
Metronidasool for Bacterial Vaginosis and Trichomoniasis
Metronidasool is commonly prescribed for bacterial vaginosis (BV), a condition that occurs when the normal balance of bacteria in the vagina changes.
It can be used orally or as a vaginal gel to treat symptomatic bacterial vaginosis. The appropriate form, dosage, and treatment duration depend on the specific product and the healthcare professional’s instructions.
Metronidasool is also an established treatment for trichomoniasis. Unlike bacterial vaginosis, trichomoniasis is a sexually transmitted infection caused by a parasite called Trichomonas vaginalis.
Oral metronidazole is used to treat this infection. The recommended treatment regimen can differ between men and women, so patients should follow the specific instructions provided by their healthcare professional.
Treating sexual partners is also important when managing trichomoniasis. Partners may need treatment to prevent the infection from passing back and forth. Patients are generally advised to avoid sexual activity until they and their partners have completed treatment and their symptoms have resolved.
Bacterial vaginosis is different from trichomoniasis. Routine treatment of sexual partners is generally not recommended for bacterial vaginosis under current CDC guidance.
Stomach and Intestinal Infections
Metronidasool can treat certain infections affecting the digestive system, but it is not a general treatment for stomach pain, diarrhea, or other digestive problems.
One of its important uses is treating intestinal amebiasis, also known as amoebiasis. This infection is caused by the parasite Entamoeba histolytica and can affect the intestines, sometimes causing diarrhea and abdominal discomfort.
In some cases, the parasite can spread beyond the intestines and affect the liver. Metronidazole may be prescribed for an amebic liver abscess when appropriate.
Doctors may also use metronidazole to treat certain serious infections inside the abdomen, particularly when anaerobic bacteria are involved.
Some abdominal infections involve several types of bacteria. In these situations, metronidasool may be combined with another antibiotic to provide broader treatment.
However, medication alone is not always enough. Some infections, such as abscesses, may require drainage to remove infected fluid or pus.
People experiencing stomach pain or diarrhea should not take leftover Metronidasool without medical advice. The symptoms may have several possible causes, and the correct treatment depends on identifying the underlying condition.

Dental Infections and Rosacea
Metronidasool has applications in both dental care and dermatology.
Dentists may prescribe metronidazole for certain gum infections and dental abscesses, particularly when anaerobic bacteria are involved.
However, antibiotics do not always resolve the underlying cause of dental pain. An infected tooth may require dental treatment, and some abscesses need drainage. Treatment of the affected tooth or gums may also be necessary.
Metronidasool is also used in topical form to treat rosacea, a long-term skin condition that commonly affects the face. Rosacea can cause redness, spots, bumps, and other skin changes.
For this condition, metronidazole may be applied directly to the skin as a cream or gel. This is different from taking oral tablets to treat an internal infection.
The form of Metronidasool is important because oral, vaginal, topical, and injectable products are designed for different purposes. Patients should use only the form prescribed or recommended for their specific condition.
Benefits of Metronidasool
Metronidasool is useful because it works against certain bacteria and parasites that cause infections.
One of its main benefits is its activity against anaerobic bacteria. These organisms can grow in areas with little oxygen and may contribute to infections in the abdomen, pelvis, and mouth.
The medicine also has antiprotozoal properties, allowing it to treat certain parasitic infections, including trichomoniasis and amebiasis.
Another benefit is its availability in several forms. Tablets and liquid preparations can be used for certain internal infections, vaginal products can treat some vaginal conditions, and creams or gels can be used for specific skin problems.
Metronidasool can also be combined with other antibiotics when an infection involves different types of bacteria that require more than one medicine.
Despite these benefits, its effectiveness depends on using it for the correct condition. It does not treat every bacterial infection, parasitic illness, or other cause of disease.
Common Side Effects
Like other prescription medicines, Metronidasool can cause side effects. Not everyone experiences them, and their severity can vary.
Common side effects include:
- Nausea
- Vomiting
- Diarrhea
- Reduced appetite
- Headache
- Stomach discomfort
- A metallic taste in the mouth
A metallic taste is a recognized side effect of metronidazole and can be unpleasant for some people. Mild digestive problems may also occur during treatment and may improve after the medicine is stopped.
Patients should speak with a doctor or pharmacist if side effects become severe, are difficult to manage, or do not improve.
Serious Side Effects and When to Get Medical Help
Although serious reactions are less common, some symptoms require prompt medical attention.
Seek urgent medical help if you experience symptoms such as difficulty breathing, swelling of the face or throat, a severe rash, seizures, or significant confusion. Yellowing of the skin or eyes can also be a warning sign that needs medical assessment.
New numbness, tingling, or other unusual nerve-related symptoms should be reported promptly to a healthcare professional.
Patients should also contact their prescriber if their infection gets worse, does not improve as expected, or returns after treatment.
Do not increase the dose, extend the treatment period, or begin another course of Metronidasool without medical advice.
Metronidasool and Alcohol
Metronidasool has an important alcohol-related warning.
The prescribing information described in the reference advises avoiding alcoholic drinks and products containing propylene glycol while taking metronidazole and for at least three days after the final dose.
Combining alcohol with the medicine may cause symptoms such as nausea, vomiting, stomach cramps, headache, and flushing.
However, official recommendations can differ between countries. The NHS guidance described in the reference advises avoiding alcohol during treatment and for two days after finishing metronidazole, while the U.S. prescribing information recommends waiting at least three days.
Because these instructions vary, patients should follow the directions supplied with their own medicine and consult their doctor or pharmacist if they are unsure.
Precautions and Drug Interactions
Before starting Metronidasool, patients should tell their healthcare professional about all the medicines they use. This includes prescription medicines, over-the-counter products, vitamins, and supplements.
Metronidazole can interact with certain medicines, potentially affecting treatment or increasing the risk of side effects.
One important example is disulfiram. The U.S. drug information described in the reference warns against using metronidazole in people who have taken disulfiram within the previous two weeks because serious mental reactions have been reported.
Patients should also tell their doctor if they are pregnant or breastfeeding. Medical advice is particularly important for people with liver disease, blood disorders, or nervous-system problems.
Special care is required for people with Cockayne syndrome, a rare genetic condition. Severe liver injury has been reported in people with this condition who received systemic metronidazole.
Providing a complete list of medicines and relevant health conditions helps a healthcare professional assess whether Metronidasool is suitable.
What Metronidasool Does Not Treat
Metronidasool is not appropriate for every infection or illness.
It does not treat viral infections such as the common cold or flu. Antibiotics work against bacteria, not viruses, so using metronidazole for a viral illness will not treat the underlying cause.
It is also not normally a standard treatment for a typical urinary tract infection (UTI). Many common UTIs are caused by bacteria that are usually treated with other antibiotics.
Symptoms alone do not always reveal the organism responsible for an infection. A healthcare professional may recommend a urine test, swab, stool test, or another investigation before selecting treatment.
Metronidasool should not be taken simply because another antibiotic has failed. Different infections require different medicines, and the correct treatment depends on the cause.
Safe Use and Storage
Metronidasool should be used exactly as directed by a healthcare professional or according to the instructions supplied with the medicine.
Keep the medicine in its original container and follow the storage instructions on the label. Storage requirements may differ depending on whether the product is a tablet, liquid, cream, gel, or another formulation.
Do not share Metronidasool with another person, even if they appear to have similar symptoms. Similar symptoms can have different causes and may require different treatments.
Leftover metronidazole should not be used to treat a new infection without medical advice.
If you miss a dose or are uncertain about a possible drug interaction, check the medicine instructions or contact a pharmacist or prescriber. Avoid changing the treatment plan on your own.
Bottom Line
Metronidasool is another-language name for metronidazole, a prescription medicine used to treat certain bacterial and parasitic infections.
It may be prescribed for bacterial vaginosis, trichomoniasis, amebiasis, certain anaerobic infections, some dental infections, and rosacea. Different forms are available for different medical conditions.
There is no single dosage that is suitable for everyone. The correct dose, formulation, and treatment duration depend on the infection and the patient’s circumstances.
Metronidazole can cause side effects and interact with other medicines. Alcohol precautions are particularly important, and recommendations may vary depending on the country and product.
Patients should follow the instructions provided with their medicine and use Metronidasool only for the condition for which it was prescribed.
