Metronidazole is an antibiotic that works by killing bacteria and parasites in your body — it stops them from growing and multiplying, which helps your body fight off the infection.
Prescription Required
You need a doctor's prescription to buy this drug.
Explore this drug
For most infections, adults take 400mg (one 400mg tablet) three times a day for 7 days. Swallow with a full glass of water. You can take it with or after food to reduce stomach upset. For amoeba infections, your doctor may prescribe 800mg (two 400mg tablets) three times daily for 5-10 days. Always complete the full course even if you feel better.
If you miss a dose, take it as soon as you remember. But if it's almost time for your next dose, skip the missed one and continue your normal schedule. Do not take two doses at once to make up for it.
Important for antibiotics
Always complete the full course even if you feel better. Stopping early can cause the infection to return and become drug-resistant.
Do not drink any alcohol — not even palm wine, ogogoro, or beer — while on this drug, as the reaction can be very serious. Always complete the full course of treatment even if you feel better after 2-3 days, otherwise the infection can come back stronger. Buy only from a reputable pharmacy — brands like Flagyl, Ausgyl, Amibagyl, or Avrogyl — and avoid buying from roadside vendors or open markets where storage may be poor.
Alcohol — DO NOT drink alcohol while taking metronidazole and for at least 48 hours after finishing, as it can cause severe nausea, vomiting, stomach cramps, and flushing. Blood thinners like warfarin — metronidazole can increase bleeding risk, so inform your doctor. Lithium — if you take lithium for mental health, metronidazole can increase its levels dangerously.
