Abstract

Objective: Our study aims to assess the frequency of self-medication in elderly people of Karachi, identify its reasons and
associated risk factors.
Study Design & Setting: This cross-sectional study was conducted in waiting areas of OPDs at Liaquat National hospital
and its outreach centers.
Methodology: Study duration was June-December, 2021. We approached all patients and aged 60 years and above. After
taking written informed consent, targeted population was interviewed to find out self-medication performed within last
three months and its reason and causes. Participants’ demographics, symptoms for which self-medication was performed,
different type of medications used, reasons of opting self-medication and different approaches for dose adjustment were
also investigated. Data was recorded by a pre-designed questionnaire. Data was analyzed using SPSS version 21.
Result: Out of 200 elderly included in the study, 87% of them reported self-medication in a 3-month recall period. Pain
(63.8%), fever (56.9%), headache (50%), cough, and cold (37.4%) were the most common symptoms. Pain killers (81.6%),
fever-reducing drugs (58%) and cough syrup (39.1%) were the top three medicines used for self-medication. One-fifth of
the respondents reported self-medication of antibiotics. Top three frequent reasons for self-medication were convenience

factors were found to be associated with self-medication practice.
Conclusion: Self-medication is a highly prevalent practice in elderly people of Karachi including non-prescribed usage
of antibiotics. Major reforms in primary health care are needed to address this growing problem
