ObjectiveThis study evaluates the self-practices with conventional and herbal drug use among ear, nose, and throat outpatients.MethodsA cross-sectional survey-based study was carried out among all ear, nose, and throat outpatients on their first visit to the otorhinolaryngology department at a tertiary care hospital. The survey comprised a total of 14 questions with 4 different sections, including demographic characteristics, self-medication of conventional medicines, herbal medication usage, and perception regarding herbal medicines.ResultsOverall, 255 questionnaires were distributed among patients, of which 183 completed the questionnaire (response rate=71.7%). Respondents reported self-medication (44.8%) with conventional drugs before visiting a hospital. The most commonly used medicine was analgesics (31.7%) and antibiotics (21.9%). Nearly half of the patients (49.2%) used at least one herbal drug. The most commonly used herbal medications were Tilia cordata (78.8%), Zingiber officinale (62.2%), and Camellia sinensis (45.5%). According to the International Union for Conservation of Nature Red List, most of the medicinal herbs were considered as data deficient/least concern. About 36.6% of the participants perceived that herbal drugs are effective for ear, nose, and throat problems. Moreover, 22.9% of the patients did not know about herbal-drug interaction with other medications.ConclusionsThis study observed a considerable prevalence of self-based practices with conventional and herbal medications. Strict national regulations on conventional and herbal medication access and long-term actions should be implemented to discourage inappropriate drug use.
