Background: Self-medication is becoming a common type of self-care behavior among the population of many countries. Obtaining and consuming drugs without the advice of physician either for diagnosis, prescription or surveillance is called self-medication.

Analysis was done using SPSS and results were presented. Chi square and odds ratio (OR) was used as statistical tool.Results: Out of 200 students, 66.5% students were from 22-24 years of age group (mean age 20.2±1.4 years, p<0.05). Prevalence of self-medication was 93%, of which 53.8% were girls and 46.2% were boys (p>0.05). Majority of the students (95.2%) were self-medicating with allopathy drugs. 51.6% responded that they were getting quick relief with self-medication. 82% were aware about the possible adverse effects (OR 0.5, p>0.05). Self-medication was practiced by 78% students for upper respiratory tract infection, headache (70%), fever (67.7%) and gastrointestinal upset (36%). Majority (83%) students consumed paracetamol tablet for various health related reasons followed by cough syrups (55.3%), nonsteroidal anti-inflammatory drugs (54.3%), antibiotics (23.1%).Conclusions: Prevalence of self-medication was high in spite of awareness of possible adverse effects amongst students.
