Ophthalmology Self-medication Practices: A Questionnaire-based Study.

: The aim of the study was to identify patterns of self-medication practices in ophthalmology.: We conducted an electronic cross-sectional descriptive survey of the Riyadh regional population in Saudi Arabia.: The study included 1354 subjects; 662 were males (49%), and 692 were females (51%). The rate of self-medication with prescription drugs (topical antibiotics and steroid-containing eye drops) in our sample was 37.2%. The number of respondents who reported using eye drops, whether it was an over-the-counter drug or a prescription drug, was 733 (54.1%). The most frequently used ophthalmic medications after lubrication drops were steroid-containing eye drops (32.6%), followed by topical decongestants (11%) and antibiotics (4.6%). The majority of steroid users (86.6%) were not aware of any steroid-related ocular complications.: Our study showed a high rate of self-medication practices along with a low level of awareness of topical medication-related side effects. If left unaddressed, this combination may result in high rates of preventable and avoidable adverse events.
