Azax 200 Suspension works by inhibiting the growth of the infection-causing bacteria and stopping it from multiplying. As a result of this, the spread of the infection is disabled. Azax 200 Suspension is usually given once a day, preferably in the morning. However, in the case of typhoid, it is to be given twice. Give it with or without food at about the same time each day. However, it is best given with food since children often have a sensitive stomach and could easily get a stomach upset.
