Self-medication in ophthalmology: A questionnaire-based study in an argentinean population

摘要

Purpose: The aim of this study was to identify practices of self-medication in the treatment of ocular conditions and to identify a profile of patients who self-medicate. Methods: We conducted a cross-sectional descriptive survey of patients, over the age of 17 years seen in our ophthalmology practice in Cordoba, Argentina. Self-medication was defined as the use of ophthalmic medicines which had not been prescribed by a health care specialist in the previous year. Results: The sample included 379 subjects, 162 males (43%) and 217 females (57%); mean age 46.8 years. Prior to looking for medical attention in our institution, 97 patients (25.6%) reported self-medicating. The most frequently employed products included non-steroidal anti-inflammatory drops in combination with a vasoconstrictive agent (32%) followed by a combination of antibiotics and steroids (9%), however, 14% of patients did not remember the name or type of medication applied. A total of 31% of patients used drugs recommended by a pharmacist; 25% used drugs of their own choosing and 24% followed suggestions from a friend or family member. Only 12% of patients knew the drug's components and only 3% were aware of any possible side effects. There was no difference in behavior patterns related to educational level or age, however, there was a significant difference related to gender, with males misusing ophthalmic drops more frequently than women (P = 0.004). Conclusions: Patients commonly attempt to treat conditions that require ophthalmologic care by self-medicating with over-the-counter eye drops. Educational efforts to inform patients of the consequences of self-medication are necessary.
