Metronidasool is another-language name for metronidazole, a prescription medicine used to treat certain bacterial and parasitic infections. In English medical information, the drug is normally called metronidazole.
People may search for Metronidasool after seeing the name on medicine information, a prescription, or a website in another language. The medicine has several uses, but it does not work against every type of infection.
This guide explains what Metronidasool is, how it works, what it treats, its forms and dosage, possible benefits, side effects, and important safety information.
What Is Metronidasool?
Metronidasool refers to metronidazole. The spelling “Metronidasool” is used in Estonian and also appears in some Afrikaans-language medical information. Metronidazole is the standard English name.
Metronidazole belongs to a group of medicines called nitroimidazoles. It has both antibacterial and antiprotozoal effects. This means it can work against certain bacteria as well as some single-celled parasites.
It is not a general antibiotic for every infection. It is especially useful against certain anaerobic bacteria. These are bacteria that can live and grow in places with little or no oxygen.
Metronidazole is also sold under different brand names. Flagyl is one well-known brand, but the available brands can differ between countries.
Metronidasool should not be considered a different active medicine from metronidazole. The difference is mainly in the name used in different languages.
How Does Metronidasool Work?
Metronidasool works after entering bacteria or parasites that are sensitive to the medicine.
Inside these organisms, metronidazole is changed into active compounds. These compounds interfere with and damage important genetic material in the organism. This prevents susceptible organisms from surviving and allows the infection to be cleared.
The medicine is particularly useful against anaerobic organisms. This is why doctors may use it for certain infections in the abdomen, pelvis, mouth, and other parts of the body.
However, the cause of an infection matters. Metronidasool should not be taken simply because another antibiotic did not work.
Different bacteria need different medicines. Some infections are caused by viruses, fungi, or parasites rather than bacteria. A doctor may therefore use a swab, stool test, blood test, or another clinical test when the cause is not clear.
What Is Metronidasool Used For?
Metronidasool has several established medical uses. The correct use depends on the type of infection, the organism causing it, and where the infection is located.
It may be prescribed for conditions such as:
- Bacterial vaginosis
- Trichomoniasis
- Amebiasis
- Amebic liver abscess
- Certain infections inside the abdomen
- Some pelvic infections
- Certain anaerobic bacterial infections
- Some gum infections and dental abscesses
- Rosacea when a suitable topical form is used
Metronidazole may also be used as part of treatment for some more complex infections. In these cases, another antibiotic may be given with it. This is useful when several types of bacteria may be causing the infection.
The medicine is available in different forms because not every condition needs the same type of treatment. For example, a skin condition may be treated with a topical product, while some internal infections require oral or intravenous medicine.
The exact treatment should be chosen according to the diagnosis rather than symptoms alone.
Metronidasool for Bacterial Vaginosis and Trichomoniasis
Metronidazole is commonly used to treat bacterial vaginosis (BV). BV happens when the normal balance of bacteria in the vagina changes.
Metronidazole can be used orally or as a vaginal gel for BV. The CDC lists both oral metronidazole and metronidazole vaginal gel among recommended treatment options for symptomatic BV. The exact dose and length of treatment depend on the product and treatment plan.
Metronidasool is also used for trichomoniasis. Unlike BV, trichomoniasis is a sexually transmitted infection. It is caused by a parasite called Trichomonas vaginalis.
Oral metronidazole is an established treatment for this infection. CDC guidance uses different recommended regimens for women and men, so patients should follow the exact instructions given by their healthcare professional.
Managing sexual partners is also important with trichomoniasis. Partners may need treatment to reduce the risk of passing the infection back and forth. People being treated are advised to avoid sex until they and their partners have completed treatment and symptoms have resolved.
Bacterial vaginosis is different. Routine treatment of a sexual partner is generally not recommended for BV under current CDC guidance.
Stomach and Intestinal Infections
Metronidasool can treat certain infections involving the digestive system, but it is not a medicine for every stomach problem or case of diarrhea.
One important use is intestinal amebiasis, also known as intestinal amoebiasis. This infection is caused by the parasite Entamoeba histolytica. It can affect the intestines and may cause symptoms such as diarrhea and abdominal discomfort.
The infection can sometimes spread outside the intestine. Metronidazole can be used in suitable cases of amebic liver abscess, where infection affects the liver.
Doctors may also use metronidazole for certain serious infections inside the abdomen when susceptible anaerobic bacteria are involved.
Some abdominal infections contain more than one type of bacteria. Metronidazole may then be combined with another antibiotic that covers organisms it does not treat well.
Medicine alone is also not enough for every infection. For example, an abscess is a collection of infected fluid or pus. Some abscesses need to be drained as part of treatment.
For this reason, stomach pain, diarrhea, or other digestive symptoms should not be treated with leftover Metronidasool without knowing the cause.
Dental Infections and Rosacea
Metronidasool also has uses in dental care and skin treatment.
Dentists may prescribe metronidazole for certain gum infections or dental abscesses, especially when anaerobic bacteria are involved.
However, an antibiotic does not always fix the cause of dental pain. An infected or damaged tooth may still need dental treatment. An abscess may need drainage, while other cases may require treatment of the affected tooth or gums.
Metronidazole also has a different use in rosacea. Rosacea is a long-term skin condition that commonly affects the face. It can cause redness, spots, bumps, and other skin changes.
For rosacea, metronidazole can be applied directly to the skin as a cream or gel. This is different from taking metronidazole tablets for an internal infection.
The form of Metronidasool matters because oral, vaginal, topical, and injectable products are made for different uses. 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. It is especially active against some anaerobic bacteria, which can grow in places with little oxygen.
The medicine also has antiprotozoal action. This allows it to treat certain parasitic infections, including trichomoniasis and amebiasis.
Another benefit is that metronidazole comes in different forms. Tablets and liquids can be used for some internal infections. Vaginal products can treat certain vaginal infections, while creams and gels can be used on the skin.
Doctors can also use metronidazole with other antibiotics when one medicine does not cover all the bacteria involved in an infection.
Its usefulness depends on having the correct diagnosis. Metronidasool does not work against every bacterium, parasite, or infection.
Common Side Effects
Like other medicines, Metronidasool can cause side effects. Not everyone will experience them.
Common side effects can include nausea, vomiting, diarrhea, reduced appetite, headache, stomach discomfort, and a metallic taste in the mouth.
The metallic taste can be unpleasant, but it is a known effect of metronidazole. Mild stomach problems may also improve after treatment ends.
Patients should speak with a doctor or pharmacist if side effects become difficult to manage, are severe, or do not improve.
Serious Side Effects and When to Get Medical Help
Some reactions need quick medical attention.
Seek urgent medical help for symptoms such as trouble breathing, swelling of the face or throat, a severe rash, seizures, or major confusion. Yellow skin or eyes can also be a warning sign that needs medical attention.
New numbness, tingling, or other unusual nerve symptoms should also be reported promptly.
Patients should contact their prescriber if the infection gets worse or does not improve as expected. Medical advice may also be needed if the symptoms return after treatment.
Do not increase the dose or start another course of Metronidasool without medical advice.
Metronidasool and Alcohol
Metronidazole has an important alcohol warning.
The source material reports that current U.S. prescribing information advises avoiding alcoholic drinks and products containing propylene glycol while using metronidazole and for at least three days after the final dose.
Using them together may cause symptoms such as nausea, vomiting, stomach cramps, headache, and flushing.
Official advice is not the same everywhere. The NHS guidance cited in the collected material says to avoid alcohol during treatment and for two days after finishing metronidazole. U.S. labeling described in the source uses at least three days after the final dose.
Because instructions can differ, patients should follow the directions supplied with their own medicine and the advice of their doctor or pharmacist.
Precautions and Drug Interactions
Before taking Metronidasool, patients should tell their doctor about all medicines they use. This includes prescription drugs, over-the-counter medicines, vitamins, and supplements.
Metronidazole can interact with some medicines.
One important example is disulfiram. The collected U.S. drug information warns against giving metronidazole to someone who has taken disulfiram within the previous two weeks because serious mental reactions have been reported.
Patients should also tell their healthcare professional if they are pregnant or breastfeeding. Medical advice is also important for people with liver disease, blood disorders, or nervous-system problems.
Special care is needed for people with Cockayne syndrome. Severe liver injury has been reported when systemic metronidazole was used in people with this rare genetic condition.
The safest approach is to give the doctor or pharmacist a complete list of medicines and important health conditions before starting treatment.
What Metronidasool Does Not Treat
Metronidasool is not suitable for every infection.
It does not treat viral illnesses such as the common cold or flu. Antibiotics work against bacteria, not viruses. Using an antibiotic when it is not needed can cause side effects without treating the illness.
Metronidazole 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 cannot always show which organism is causing an infection. A doctor may sometimes need a urine test, swab, stool test, or another test before choosing treatment.
Metronidasool should also not be taken simply because another antibiotic did not work. The correct medicine depends on the cause of the infection.
Safe Use and Storage
Use Metronidasool exactly as directed by a healthcare professional or according to the instructions supplied with the medicine.
Keep it in its original container and follow the storage directions on the label. Storage requirements can differ between tablets, liquids, creams, gels, and other products.
Do not share the medicine with another person, even if that person has similar symptoms. Two illnesses can feel the same but have different causes.
Leftover metronidazole should not be used for a new infection without medical advice.
If you miss a dose or are unsure about an interaction, check the medicine instructions or contact a pharmacist or prescriber. It is safer to ask than to change the treatment plan yourself.
Bottom Line
Metronidasool is a name used for metronidazole, a prescription medicine that works against certain bacteria and parasites.
It can be used for conditions such as bacterial vaginosis, trichomoniasis, amebiasis, certain anaerobic infections, some dental infections, and rosacea. Different forms are available for different conditions.
There is no single dose that is right for everyone. The correct dose, form, and treatment length depend on the infection and the patient.
Metronidazole can also cause side effects and interact with other medicines. Alcohol instructions are especially important. Patients should follow the directions provided with their medicine and use Metronidasool only for the condition for which it was prescribed.
