Pharmaceutical Intervention aims to optimize and rationalize the use, effectiveness, and safety of dispensed medications resolving drug-related problems (DRPs) and negative medicine outcomes (NMOs). To evaluate Pharmaceutical Interventions in Benzodiazepines users during the COVID-19 pandemic from a Community Pharmacy. Prospective observational, descriptive, and cross-sectional study (AEMPS code: DAA-CLO-2020-01) of Pharmaceutical Interventions offered by the community pharmacy between August 2020 and February 2021. A total of 306 Pharmaceutical Interventions were conducted involving 127 patients. Health education and personalized medication information were the most common Pharmaceutical Interventions after detecting a high level of unfamiliarity with the Benzodiazepines among patients. Pharmaceutical Interventions leading to medical referrals accounted for 37.8% of the total, triggered by the detection of DRPs and/or NMOs or after identifying the patient as candidate for deprescription. These referrals included patients with a very high level of depression according to the Euroqol 5D-3L test. Pharmaceutical Interventions resulting in Medication Review with Follow-up Service were performed in 3.1% of patients. The patient acceptance rate of Pharmaceutical Interventions reached 98.4%. The high acceptance rate of Pharmaceutical Interventions reinforces the value of Community Pharmacy in optimizing and rationalizing Benzodiazepines usage, while strengthening the pharmacist-patient relationship. The COVID-19 pandemic posed challenges to pharmacist-physician collaboration despite of the availability of telecommunication protocols among healthcare professionals.
