What is Metronidazole (Flagyl, Likmez)?
Metronidazole belongs to a group of medications called nitroimidazoles. It works by attacking and disrupting the DNA of bacteria and parasites, preventing them from reproducing and spreading.
This makes Metronidazole an excellent choice for treating anaerobic bacterial infections (those that thrive without oxygen) and certain parasitic diseases.
Available in oral, topical, and intravenous forms, Metronidazole is commonly prescribed to treat infections in the digestive system, skin, and reproductive organs, among others.

Key Uses of Metronidazole (Flagyl, Likmez)
1. Treating Bacterial Infections
Metronidazole is especially effective for treating infections caused by anaerobic bacteria. Some of the bacterial conditions it is commonly used for include:
- Pelvic Inflammatory Disease (PID)
- Bacterial Vaginosis (BV)
- Diverticulitis and other gastrointestinal infections
- Infections after abdominal surgery
2. Fighting Protozoal Infections
In addition to bacterial infections, Metronidazole also fights parasitic infections. It is commonly prescribed for:
- Giardiasis, an intestinal infection caused by the Giardia parasite
- Amebiasis, a parasitic infection affecting the intestines
- Trichomoniasis, a sexually transmitted infection caused by Trichomonas vaginalis
3. Managing Skin and Soft Tissue Infections
Metronidazole is often used to treat infections of the skin and tissues, such as rosacea, a skin condition that causes facial redness and pimples. It also helps in treating soft tissue infections caused by bacteria.
4. Oral Infections
Metronidazole is sometimes prescribed for dental infections, especially those caused by anaerobic bacteria that are often found in the mouth.
How Does Metronidazole Work?
Metronidazole works by entering the bacteria or parasite’s cell and disrupting its DNA, preventing it from multiplying. This mechanism helps eliminate harmful microorganisms and treats a variety of infections. Its effectiveness against anaerobic organisms makes it especially valuable in treating infections where other antibiotics might fail.
Dosage and How to Use Metronidazole
Metronidazole comes in different forms, including oral tablets, capsules, topical creams, and intravenous injections. The dose depends on the infection type and severity:
- Bacterial Vaginosis: Usually, 500 mg twice daily for 7 days (oral form)
- Trichomoniasis: A single dose of 2 grams orally
- Intestinal infections: Typically, 500 mg every 6-8 hours for up to 10 days
It’s crucial to follow your doctor’s instructions and complete the full course, even if you feel better before finishing.
Tip: It’s best to take Metronidazole with food or a full glass of water to reduce stomach upset.
Potential Side Effects of Metronidazole
Like all medications, Metronidazole can have side effects. Most are mild, but some can be more serious. Here are some common and severe side effects:
Common Side Effects:
- Nausea and Vomiting: These can occur, especially when the drug is taken on an empty stomach.
- Metallic Taste: A distinctive metallic taste is often experienced, which can be unpleasant.
- Headaches: Some individuals may experience mild to moderate headaches.
- Diarrhea and Stomach Pain: Digestive upset, including loose stools or stomach cramps, is common.
- Dark Urine: Metronidazole can cause the urine to turn reddish-brown, which is harmless.
Serious Side Effects:
- Severe Allergic Reactions: Symptoms may include rash, itching, swelling, and difficulty breathing.
- Clostridium difficile Infection: This rare but serious condition causes severe diarrhea and abdominal pain.
- Nerve Damage: Long-term use of Metronidazole can sometimes lead to peripheral neuropathy, causing numbness and tingling in the hands and feet.
- Liver Issues: Symptoms like yellowing of the skin or eyes, dark urine, or unusual fatigue may signal liver problems.
Safety Considerations and Important Precautions
1. Avoid Alcohol
It’s essential to avoid alcohol while taking Metronidazole, as the combination can cause a severe reaction known as the disulfiram-like effect. Symptoms include nausea, vomiting, flushing, and headaches.
2. Pregnancy and Breastfeeding
Metronidazole should only be used during pregnancy if absolutely necessary. It is typically not recommended during the first trimester, and if you are breastfeeding, talk to your doctor before using the medication.
3. Liver Function
If you have a history of liver disease, Metronidazole should be used with caution. Your doctor may adjust the dosage or recommend monitoring your liver function.
4. Drug Interactions
Metronidazole can interact with other medications, including:
- Blood thinners (e.g., warfarin)
- Lithium
- Antiepileptic drugs
Be sure to inform your healthcare provider of all the medications, supplements, and over-the-counter drugs you are using.
How to Take Metronidazole Safely
- Stick to the prescribed dosage: Never adjust your dose without consulting your doctor.
- Complete the full course: Even if you start feeling better, don’t stop taking the medication early.
- Stay hydrated: Drink plenty of water while on Metronidazole, especially if you experience diarrhea.
- Watch for side effects: If you notice any unusual symptoms, contact your doctor immediately.
