✔ Helps Manage IBS-D

✔ Controls Intestinal Bacterial Overgrowth

Summary: Rifaximin works mainly inside the intestine, making it an effective treatment for selected gastrointestinal bacterial conditions.

How Does FIXIARK-400 Tablet Work?

Rifaximin 400mg blocks bacterial RNA polymerase, preventing bacteria from producing essential proteins needed for survival and multiplication. As a result, harmful bacteria stop growing and gradually die.

Unlike many antibiotics, Rifaximin remains largely inside the digestive tract, allowing targeted treatment with limited absorption into the bloodstream.

How It Works

• Stops bacterial RNA synthesis

• Prevents bacterial multiplication

• Reduces harmful intestinal bacteria

• Helps lower toxin production in the gut

• Improves gastrointestinal health

Because it acts locally within the intestine, Rifaximin is particularly useful for gastrointestinal conditions where bacterial overgrowth plays a key role.
