Flagyl, also known as metronidazole, is an antibiotic medication that fights bacteria in the body. It is used to treat a broad range of infections caused by certain types of bacteria and parasites. Flagyl belongs to a class of drugs known as nitroimidazoles, which disrupt the DNA of bacterial cells, preventing them from growing and spreading.Metronidazole is a colorless to slightly yellow crystalline powder. It is slightly soluble in alcohol and has a solubility in water and saline. It is available in several forms, including tablets, cream, gel, and injection.

Each oral tablet contains 250 mg or 500 mg of metronidazole. In addition to the active ingredient, the tablets also contain inactive ingredients such as cellulose, FD&C Blue No. 2 Lake, hydroxypropyl cellulose, hypromellose, polyethylene glycol, stearic acid, and titanium dioxide.Flagyl’s potency, broad-spectrum antibacterial action, and high tissue penetration make it a valuable resource in the treatment of a variety of infections. It is a critical part of the healthcare arsenal and continues to be widely used in clinical practice.

How Does Flagyl Work?

Flagyl, or metronidazole, works by entering bacterial and protozoal cells and interfering with their DNA. It damages the DNA and also prevents the bacteria and protozoa from forming new DNA. This ultimately results in their death. This compound is readily absorbed when taken orally, and it is able to penetrate bone, making it particularly useful in oral/dental infections.

The precise mechanism of action of metronidazole is not fully understood, but it is believed to work by inhibiting the synthesis of certain components within the bacterial cell, leading to cell death. It is also thought to have an immunosuppressive effect, reducing inflammation and swelling in affected tissues.

Flagyl’s mechanism of action is unique among antibiotics and offers a specialized approach to treating certain types of infections. It is only effective against anaerobic organisms, bacteria that thrive in low oxygen environments, and certain parasites.

Indications and Usage

Flagyl is indicated for the treatment of various infections caused by susceptible anaerobic bacteria and certain parasites. These conditions include:

  • Bacterial vaginosis: This is a type of vaginal inflammation caused by an overgrowth of bacteria naturally found in the vagina.
  • Certain types of infections, such as skin, bone, stomach, brain, blood, lungs, heart, and female genital tract infections.
  • Trichomoniasis: This is a sexually transmitted infection caused by a parasite.
  • Giardiasis: An infection in the small intestine caused by a tiny parasite called Giardia lamblia.
  • Amoebiasis: This is an infection caused by a parasite called Entamoeba histolytica.

In addition to these uses, Flagyl is also used in combination with other antibiotics to treat certain types of bacterial infections. It is essential to note that Flagyl is not effective against infections caused by viruses, such as the common cold or flu.


Flagyl is contraindicated in certain conditions and should not be used in these cases. These include:

  • Patients with a known hypersensitivity to metronidazole or other nitroimidazole derivatives.
  • Patients with a history of blood disorders or leukopenia, especially if these conditions were caused by a previous course of metronidazole.
  • Patients with active neurological disorders or a history of seizures, as there have been reports of convulsive seizures and peripheral neuropathy in patients while on therapy with metronidazole.
  • Patients with active disease of the Central Nervous System.
  • Pregnancy: Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. It should not be used in pregnant patients during the first trimester.

Before starting treatment, a thorough medical evaluation should be done to determine if any of these contraindications exist.


The dosage and duration of Flagyl therapy depend on the specific infection being treated. It is critical to take this medication exactly as prescribed by your healthcare provider. Do not take more or less of it or take it more often than prescribed by your doctor.

For instance, in treating trichomoniasis, the typical dosage for adults is 2 grams of Flagyl given as a single dose or divided doses over one day. For bacterial vaginosis, a typical dosage might be 500 mg twice daily for seven days. The dose for children will depend on their weight.

Flagyl can be taken with or without food. If the medication causes stomach upset, taking it with a meal or a small snack may help. It’s crucial to complete the full course of therapy, even if symptoms improve before the medication is finished. Not completing the treatment may allow the infection to return and potentially become resistant to the antibiotic.


Before taking Flagyl, inform your healthcare provider if you have:

  • Liver disease: Metronidazole is processed by the liver. If you have liver disease or reduced liver function, your body may process this drug more slowly, increasing the risk of side effects.
  • A history of blood disorders: Metronidazole may cause a decrease in some types of blood cells, increasing the risk of infections or bleeding.
  • A history of nerve disorders or seizures: Metronidazole may cause nerve damage, leading to numbness and tingling in the hands and feet.
  • Allergies to any medications, including antibiotics.

Also, alcohol should be avoided during treatment and for at least three days after finishing the medication because a disulfiram-like reaction (flushing, vomiting, abdominal cramps) may occur.


As with any medication, Flagyl can cause side effects. Common side effects include:

  • Nausea, vomiting, loss of appetite, or metallic taste in the mouth.
  • Diarrhea, constipation, or stomach cramps.
  • Dry mouth, dark-colored urine.
  • Dizziness, feeling tired.
  • Mild skin rash or itching.

Less common but more serious side effects include seizures, numbness or tingling in the hands or feet, unsteadiness, hearing loss, or severe skin reactions. If any of these occur, seek immediate medical attention.
