Patient summary

Utilized to target bacterial and protozoal infection to alleviate symptoms and resolve the underlying infection.

Mechanism of action

Metronidazole is a nitroimidazole derivative that disrupts bacterial and protozoal metabolic processes. Once inside the cell, it is reduced, creating intermediates that damage DNA, thereby inhibiting nucleic acid synthesis and causing cell death.

Pregnancy and breastfeeding

Pregnancy: Avoid during the first trimester. Breastfeeding: Suspend breastfeeding during treatment.

What you will receive

Flagyl is the originator brand name, made by Sanofi. We use it here to identify the medicine only; we are not affiliated with Sanofi and do not ship the original Flagyl.

  • You receive a generic equivalent: the same active ingredient (Metronidazole) at the same dose, mostly recognised Indian branded generics from vetted manufacturers.
  • The exact brand supplied depends on what is in stock at the dispatching warehouse.
  • A regulated generic matches the original ingredient for ingredient by legal standard.

About Flagyl

Flagyl is a treatment by Sanofi containing the active ingredient metronidazole, used for bacterial infection, protozoal infection and bacterial vaginosis. Supplied as a tablet in strengths of 200mg and 400mg, this medication is a common option for managing these concerns.

Flagyl availability in Asia

Flagyl is registered across 14 markets including Hong Kong, Thailand and Malaysia, with availability also in the Philippines, Indonesia and Taiwan.

This medication is best used under a doctor’s care.
