Abstract: Conjunctivitis is usually of infective origin and is caused by bacteria, virus or chlamydia. Antibiotics are mainly prescribed for quick recovery of the patient and for speeding up the eradication. This study was done to evaluate the prescribing pattern of antibiotics in the conjunctivitis patients and to know the susceptibility of the pathogens to the antibiotic. Based on the inclusion and exclusion criteria, fifty subjects who are having conjunctivitis were selected and evaluated for the prescribing pattern of antibiotics.Conjuctival swab was collected and inoculated in the culture media. The cultures were analysed for growth and the organism was identified based on gram staining and tests. The antibiotic sensitivity tests were done by disc diffusion method. Flouroquinolones were the most commonly prescribed antibiotics (94%). Among the flouroquinolones, Moxifloxacin was the most commonly (52%) prescribed drug.Staphylococcus aureus has the highest occurrence (92.3%) followed by P. aeruginosa at 4% isolated from the conjuctival swab.Moxifloxacin has the highest zone of inhibition followed by ciprofloxacin and ofloxacin in S.aureus isolates. Antibiotics were correctly prescribed in case of conjunctivitisof bacterial origin and antibiotics were assumed to be prescribed to prevent secondary infections in suspected case of viral origin.
