Introduction The benefits of antibiotics are under threat by self-medication, which culminated in economic burdening of developing countries, treatment failures, the emergence of antibiotic-resistant strains of bacteria and an increased probability of exposure and infection of the general population by antibiotic-resistant bacterial strains. Objectives This study aimed to evaluate the knowledge and attitude of medical students in Sudan towards the use of antibiotics, the prevalence of self-medication with antibiotics among medical students in Sudan and to identify risk factors which promote self-medication with antibiotics. Materials and methods This was a cross-sectional, descriptive and institution-based study, between November 2020 and May 2021. 1,110 medical students were selected by multistage cluster sampling. Logistic regression was used to identify risk factors of self-medication with antibiotics among the study participants. Results The median knowledge score was 7 out of a maximum of 10 (IQR: 5–8). A moderately positive attitude was observed among the participants (Median: 7/10; IQR: 6–8). Knowledge and attitude scores were significantly associated with academic year and monthly allowance (p < 0.05). 675 (60.8%) self-medicated with antibiotics within the previous 12 months, mostly from community pharmacies (321/675; 47.5%). Antibiotics were most commonly used to treat respiratory tract infections (38.1%) and cough (30.4%). Chi-square analysis demonstrated that self-medication with antibiotics was significantly associated with gender, year of study and monthly income. Conclusions Undergraduate medical students had moderate knowledge and attitude towards antibiotic use and antibiotic resistance, and an alarmingly high prevalence of self-medication with antibiotics. This highlights the urgent need for tighter legislation regarding the sales of antibiotics in community pharmacies by the state and federal health ministries.
