Introduction

Flagyl (metronidazole) is an antibiotic and antiprotozoal medication used to treat various infections, including bacterial infections of the stomach, liver, skin, joints, brain, and respiratory tract, as well as certain sexually transmitted infections. It works by stopping the growth of bacteria and protozoa that cause infections.

Side Effects

The most common side effects of Flagyl (metronidazole) include gastrointestinal issues such as nausea and a metallic taste. If any side effects persist or worsen, consult your healthcare provider.

Common side effects include:

  • Nausea

  • Upset stomach

  • Diarrhea

  • Headache

  • Metallic taste in the mouth

Flagyl (metronidazole) has been linked to an increased risk of neurological symptoms, including seizures and peripheral neuropathy (e.g., numbness). It’s important to stop using metronidazole and talk with your healthcare provider if you notice neurological symptoms, including: 

  • Dizziness

  • Fainting

  • Vertigo

  • Loss of coordination

  • Ringing in ears (tinnitus)

  • Hearing loss

  • Confusion 

In rare cases, Flagyl (metronidazole) has been associated with severe allergic reactions, including anaphylaxis and a progressive skin condition called Stevens-Johnson syndrome (SJS). If you develop a skin rash or swelling around the neck or face and difficulty breathing, seek medical attention immediately. 

Metronidazole has also been associated with an increased risk of vaginal yeast infections. 

Metronidazole should not be combined with alcohol. Mixing metronidazole with alcohol can result in a disulfiram-like reaction. This can cause symptoms like accelerated heart rate, skin flushing, nausea and vomiting, or visual disturbances. 

Dosage Information

The dosage of Flagyl (metronidazole) depends on the patient's individual needs, including the type and severity of the infection being treated. For many infections, a standard dose is 500 mg, taken orally two to three times daily for 7 to 10 days. For certain infections, such as trichomoniasis, a single large dose may be prescribed.

Dosage adjustments may be recommended for individuals with reduced liver function or who are on dialysis. Certain dialysis methods can be more or less likely to impact metronidazole levels. Some infections require more aggressive treatment than others. Consult your healthcare provider to better understand the unique risks and benefits associated with your needs.

Common Questions

Common questions and answers about Flagyl (metronidazole):

How quickly does Flagyl work?

Flagyl (metronidazole) usually starts working within a few days, though the exact timing depends on the infection being treated. Many patients begin to feel better within 48-72 hours, but it is essential to complete the entire course of medication to ensure the infection is fully eradicated.

Do I need to take Flagyl with food?

Flagyl (metronidazole) can be taken with or without food, but taking it with food may help reduce stomach upset, a common side effect. Follow your healthcare provider’s recommendations and try to take it at evenly spaced intervals to maintain a consistent level of the medication in your bloodstream. Avoid alcohol while taking Flagyl, as it can cause severe nausea and vomiting when combined with this medication.

Metronidazole Injection Information

Metronidazole Injection



(me troe ni' da zole)

Flagyl® I.V.

Metronidazole injection can cause cancer in laboratory animals. Talk to your doctor about the risks and benefits of using this medication.

Metronidazole capsules and tablets are used to treat infections of the reproductive system, gastrointestinal (GI) tract, skin, heart, bone, joint, lung, blood, nervous system, and other areas of the body. Metronidazole capsules and tablets are also used to treat sexually transmitted diseases (STDs). Metronidazole extended-release (long-acting) tablets are used to treat bacterial vaginosis (an infection caused by too much of certain types of harmful bacteria in the vagina) in women. Metronidazole is in a class of medications called nitroimidazole antimicrobials. It works by stopping the growth of bacteria.
Antibiotics will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Metronidazole injection comes as a solution and is infused (injected slowly) intravenously (into a vein). It is usually infused over a period of 30 minutes to 1 hour every 6 hours. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to use metronidazole injection.
You may receive metronidazole injection in a hospital, or you may use the medication at home. If you will be using metronidazole injection at home, your health care provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of treatment with metronidazole injection. If your symptoms do not improve or if they get worse, call your doctor.
Use metronidazole injection until you finish the prescription, even if you feel better. If you stop using metronidazole injection too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

Before using metronidazole,

tell your doctor and pharmacist if you are allergic to metronidazole or any of the ingredients in metronidazole topical preparations. Ask your pharmacist for a list of the ingredients.

tell your doctor and pharmacist what prescription, nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven).

tell your doctor if you have or have ever had a central nervous system condition (diseases of the spinal cord or brain) or a blood disease.

tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while using metronidazole, call your doctor.

Unless your doctor tells you otherwise, continue your normal diet.
