Is Metrogyl 400 used for loose motion?

Dear Reader,

That’s a great question, and it’s important to know the difference between treating the cause and stopping the symptom.

Metrogyl 400 (metronidazole) is not a general medicine for treating loose motion directly, but it can help if your diarrhoea is caused by an infection, especially one due to bacteria or parasites such as Entamoeba histolytica (amoebiasis) or Giardia lamblia (giardiasis).

What Metrogyl 400 does:

• It kills harmful bacteria or parasites in the intestine that cause infection-related diarrhoea, stomach pain, or cramps.
• Treating the infection helps the loose motion gradually stop over a few days.

What it does not do:

• It does not work for viral diarrhoea (like from contaminated food or water).
• It doesn’t act like medications that directly stop bowel movements, and these are usually avoided in infections because they can trap germs inside.

What you can do:

• Take Metrogyl exactly as prescribed, usually after food.
• Drink plenty of fluids, such as ORS, to stay hydrated.
• Eat light, bland foods (like rice, curd, banana, toast).
• Avoid spicy, oily foods and dairy for a few days.

If your loose motions don’t improve in 2–3 days, or you notice blood in stool, high fever, or severe weakness, contact your doctor. You may need stool tests or a different treatment.

So, in short: Metrogyl 400 doesn’t stop loose motion directly, but it helps treat the infection causing it, allowing your stomach to recover naturally. Metrogyl should be taken only when prescribed by a doctor; do not self-medicate for loose motions.

Wishing you good health.
