📋 Product Specifications

How Flagyl 400mg Works

Flagyl contains Metronidazole, which works by entering susceptible bacterial and protozoal cells and disrupting their DNA, preventing them from multiplying and eventually killing them. It is particularly effective against anaerobic bacteria (which thrive without oxygen) and certain parasites such as those causing amoebiasis and giardiasis. Follow the exact dose and duration prescribed by your doctor, and complete the full course even if you start to feel better.

Flagyl 400mg Uses

Flagyl 400mg Tablet is used for:

•          Intestinal & Stomach Infections: amoebiasis and giardiasis, and other bacterial infections of the digestive tract

•          Gum & Dental Infections: infected gums, dental abscesses, and infections following dental procedures

•          Skin & Wound Infections: infected wounds, skin ulcers, and bed sores caused by susceptible anaerobic bacteria

•          Gynaecological Infections: bacterial vaginosis, trichomoniasis, and pelvic inflammatory disease, as directed by a doctor

Flagyl is not effective against viral infections such as the common cold or flu, and should only be used when a bacterial or parasitic infection is confirmed or strongly suspected by a doctor, to help reduce the risk of antibiotic resistance.

Who Should Use Flagyl 400mg

Flagyl 400mg Tablet is generally prescribed for adults and children with a confirmed or strongly suspected infection caused by bacteria or parasites sensitive to Metronidazole, who have no known allergy to Metronidazole or other nitroimidazole medicines and no severe liver disease without dose adjustment.

🚫 Who Should Avoid It

Avoid Flagyl, or use only under medical advice, if you have a known hypersensitivity to Metronidazole or other nitroimidazole antibiotics, or severe liver disease. It should generally be avoided in the first trimester of pregnancy and used only if clearly needed later in pregnancy or while breastfeeding, on your doctor's advice. Tell your doctor if you have a blood disorder or a history of seizures or nerve problems, since Metronidazole can affect these conditions.

Can It Be Taken Long Term?

Flagyl is intended for a defined, short-term course prescribed by your doctor, typically 5 to 10 days depending on the infection. It should not be used for longer than prescribed or restarted without medical advice, since prolonged or high-dose use raises the risk of nerve-related side effects and unnecessary antibiotic use increases the risk of resistance. If symptoms persist or worsen after completing the course, consult your doctor rather than repeating the course yourself.

💊 How to Take Flagyl 400mg (Dosage)

Flagyl should be taken exactly as prescribed by your doctor, generally two to three times daily depending on the infection being treated. Take it with or after food and a full glass of water to help reduce stomach upset. Swallow the tablet whole; do not chew or crush it.

Complete the full prescribed course even if you start to feel better after a few days, since stopping early can allow the infection to return and contributes to antibiotic resistance. Do not drink alcohol during treatment or for at least 48 hours after finishing the course, as combining alcohol with Metronidazole can cause an unpleasant reaction with flushing, nausea, and a fast heartbeat.

Missed Dose: If you miss a scheduled dose, take it as soon as you remember. If it is close to your next scheduled dose, skip the missed one and continue your regular schedule - do not take a double dose.

⚠️ Side Effects - What to Expect

Flagyl is generally well tolerated when taken exactly as prescribed. Side effects can include:

•          Nausea, metallic taste in the mouth, or loss of appetite (common)

•          Headache or dizziness (common)

•          Dark-coloured urine (harmless, related to how the medicine is processed by the body)

•          Numbness or tingling in the hands or feet, more likely with high-dose or prolonged use (uncommon - seek medical advice if this occurs)

•          Allergic reaction, including rash or swelling (rare, but requires immediate medical attention)

Seek medical attention promptly if you notice facial swelling, difficulty breathing, a widespread rash, seizures, or persistent numbness or tingling, as these can be signs of a serious reaction.

🛡️ Precautions and Drug Interactions

•          Alcohol: avoid alcohol during treatment and for at least 48 hours after finishing the course, to prevent an unpleasant reaction

•          Liver Disease: tell your doctor about any history of liver problems, since your dose may need to be adjusted

•          Blood Thinners: Metronidazole can enhance the effect of warfarin; tell your doctor if you take blood-thinning medicines

•          Pregnancy and Breastfeeding: generally avoided in the first trimester; use only if clearly needed later in pregnancy or while breastfeeding, on your doctor's advice

•          Nerve Problems or Seizure History: tell your doctor if you have a history of seizures or nerve-related conditions before starting treatment

•          Complete the Course: do not stop treatment early, even if you feel better, unless advised by your doctor
