Phexin 500 MG Capsule belongs to the drug group known as cephalosporin (antibiotic). It interferes in the formation of the cell walls of the bacteria. This results in the rupturing of the walls and hence kills the bacteria. The medication is available in tablet and liquid form for oral consumption.

Take the dosages as directed by the doctor. If you miss a dose, you can have it as soon as you remember about it, but skip it if the time for your next scheduled dose is near. Do not take two doses together to make up for a missed one as overdosing can lead to nausea, vomiting, stomach aches, diarrhea and blood in urine.
