Flagyl 400 Mg

Description

What is Flagyl 400 mg?

Flagyl 400 mg is a widely used antibiotic containing metronidazole 400 mg, known for treating a range of bacterial and parasitic infections. It’s part of the nitroimidazole class of antibiotics and is highly effective against infections caused by anaerobic bacteria (bacteria that thrive without oxygen) and certain parasites. Doctors often choose Flagyl 400 mg when stronger treatment is needed compared to lower doses, making it ideal for moderate to severe infections.

What is Flagyl 400 Used For?

Flagyl 400 mg is prescribed for many conditions, including:

• Bacterial vaginosis and other gynecological infections.
• Dental infections like abscesses and gum disease.
• Gastrointestinal infections, including diverticulitis and stomach ulcers, are caused by H. pylori (when used in combination therapy).
• Skin and soft tissue infections caused by anaerobic bacteria.
• Parasitic infections such as amoebiasis and giardiasis.
• Pelvic infections or infections after surgery.

Its broad-spectrum activity makes it highly versatile and dependable for both common and complex infections.

How Flagyl 400mg Works

Flagyl 400 mg contains metronidazole, which enters harmful bacteria and parasites, damaging their DNA and stopping them from growing or multiplying. This unique action helps eliminate anaerobic bacteria and protozoa that many regular antibiotics can’t target, giving patients faster relief and effective infection control.

How to Take Flagyl 400mg Tablet & Dosage Guidelines

• Always follow your doctor’s prescription — the usual dose for adults is 400 mg two to three times daily, depending on the type and severity of the infection.
• Swallow the tablet whole with water; do not crush or chew.
• Take it after meals to reduce stomach upset.
• Never skip doses and finish the entire course, even if you feel better early, to avoid antibiotic resistance or infection relapse.
• Avoid alcohol during treatment and for at least 48 hours after your last dose. Mixing alcohol with Flagyl can cause severe nausea, vomiting, and flushing.
