Mechanism of Action

Rifavax M contains two active ingredients: Rifaximin and Metronidazole.

Rifaximin is an antibiotic that works by inhibiting the growth of bacteria in the gastrointestinal tract. It specifically targets certain types of bacteria that can cause infections in the digestive system. By preventing the growth of these bacteria, Rifaximin helps to resolve the infection and alleviate symptoms.

Metronidazole is also an antibiotic that works by killing bacteria and certain parasites that can cause infections in the gastrointestinal tract. It targets the DNA of these microorganisms, disrupting their normal functioning and leading to their death.

Common side effects may include nausea, vomiting, diarrhea, abdominal pain, and headache. These side effects are generally mild and go away on their own.

However, be aware of serious side effects that may occur. If you experience any of the following symptoms, seek medical attention immediately: severe abdominal pain, persistent diarrhea, fever, bloody stools, or signs of an allergic reaction such as rash, itching, swelling, or difficulty breathing.
