Objective:
The dispensing of non-prescription antibiotics is a worldwide concern, and antibiotics should only be dispensed with a legitimate prescription.
Methodology:
A cross-sectional study was conducted using the simulated client methodology, with data collected, recorded, and analyzed using SPSS.
Results:
The simulated client visited 210 pharmacies, of which 70 dispensed antibiotics without a prescription. Outcomes The most often suggested antibiotics for upper respiratory tract infections (URTIs) were Amoxicillin (n = 17, 8.1%), Clarithromycin (n = 20, 9.5%), and Moxifloxacin (n = 13, 6.2%), with 33.3% of medications dispensed without a prescription for URTIs. Cefixime (n = 20, 9.5%) and ceftriaxone (n = 17, 8.1%) were the most often administered medications for urinary tract infections (UTIs). The non-prescribed dispensing of upper respiratory tract infections (URTIs) and urinary tract infections (UTIs) was markedly elevated (p < 0.05). Antibiotics were dispensed without a prescription for diarrheal diseases in over 50% of pharmacies, with Metronidazole (n = 23, 11%), Azithromycin (n = 16, 7.6%), and Rifaximin (n = 15, 7.1%) being the most often prescribed. In all bivariate and multivariate models, male gender was associated with reduced likelihood (COR: 0.30, 95% CI: 0.12-0.72; p = 0.0079 and AOR: 0.03, 95% CI: 0.005-0.15; p = 0.0001). Individuals aged 30 years and older exhibited increased odds of dispensing in both bivariate (COR: 3.67, 95% CI: 1.69-8.87; p = 0.0018) and multivariate analyses (AOR: 9.44, 95% CI: 2.55-61.70; p = 0.001). The presence of a pharmacist on duty markedly diminished the likelihood of administering antibiotics without a prescription (COR: 0.13, 95% CI: 0.06-0.25; p = < 0.001; AOR: 0.06, 95% CI: 0.03-0.16; p = < 0.001).
Conclusion:
These findings highlight the imperative of enforcing existing laws and implementing rigorous rules, alongside pharmacy-centered antimicrobial stewardship programs that focus on accurate dispensing practices to mitigate antimicrobial resistance.

This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
