[Oral antibiotic request without prescription in community pharmacies. Description of pharmacists' intervention]

Objectives: To quantify the proportion of oral antibiotics requests without prescription in Community Pharmacy (CP) and to analyse it causes.

Method: Cross-sectional multicentre study carried out in Spanish community pharmacies during 4 weeks, one in each season of the year. Oral J01 antibiotics (Anatomical Therapeutic Chemical classification, ATC) requested for self-medication were analysed.

Results: 247 pharmacies and 365 pharmacists participated in the study, 1172 antibiotic requests were recorded. More frequent requests for antibiotic self-medication were: previous treatment for the same symptoms (63.1%), insufficient time for a general practitioner (GP) consultation (12.1%) and patient belief that GP is going to prescribe the antibiotic (4.9%). Higher number of generic medication were requested compared to brand medication (41.1 versus 34.9%). Active ingredients commonly requested were amoxicillin (28.2%), amoxicillin-clavulanic (14.9%) and phosphomycin (21.8%) to treat upper respiratory related infections (35.1%), urinary infections (28.1%) and teeth infections (20.2%). 2406 pharmacists' interventions were carried out: referring to the GP (40.8%), information for correct use of medication (31.3%), non-pharmacological treatment (15.7%), and recommendation of a different medication (6.9%) or a different product (5.3%).

Conclusions: Nowadays higher number of active ingredients than brands are requested when selecting a treatment for an infection, mainly β-lactams and macrolides. Majority of self-medication tried to treat upper respiratory infections, urinary and teeth infections. Most frequent pharmacists' intervention was referring to the GP to obtain a correct diagnosis and treatment.
