Product introduction

Phexin DS 250 Syrup is an oral antibiotic built around cefalexin, a first-generation cephalosporin that doctors commonly prescribe for children and adults who have trouble swallowing tablets. It targets a broad range of bacteria responsible for everyday infections of the throat, ears, skin and urinary tract. Being a liquid formulation, it allows for flexible, weight-based dosing, which is especially useful in paediatric prescriptions. Like all antibiotics, it works only against bacterial infections and has no role in viral illnesses such as the common cold.

Storage: Keep the bottle tightly closed below 30°C, away from direct sunlight and moisture. Shake well before every dose and discard any leftover syrup once the course is finished.
