BACKGROUND: Primary dysmenorrhoea is one of the most common menstrual problems and has a large impact on social activities and academic performance of affected women. In spite of that, it still isn’t usual to talk about menstrual pain openly and to seek professional help in terms of pain management. ----- OBJECTIVE: To determine the prevalence, impact on quality of life and treatment of primary dysmenorrhoea among female students at the University of Zagreb. ----- PATIENTS AND METHODS: A web‐based questionnaire with questions regarding menstrual cycle and associated symptoms was distributed to university students. The group who claimed to be affected by primary dysmenorrhoea also completed questions comprising pain severity, its impact on everyday life and methods of pain reduction. ----- RESULTS: A total of 1118 female students was included in the survey. The mean SD age of the students was 21,79 ± 2,05 years. The prevalence of primary dysmenorrhoea was 91,4%. Menstrual pain was mild in 8,2% of cases, moderate in 30,7% and severe in 61,1%. Even 97,3% of the students with dysmenorrhoea reported that it limited their daily activities, but only 38,8% consulted a physician while most of them practiced selfmedication. The most common medication used was ibuprofen followed by paracetamol and ketoprofen. Alternative methods of relieving pain were used by 76,5% of the participants and the most common were use of locat heat and antalgic position. ----- CONCLUSION: Primary dysmenorrhoea has a high prevalence among female students at the University of Zagreb and it often causes decreased ability to take part in daily activities. Students usually do not seek help from health professionals. Instead of that they use self-medication. It is necessary to create a safe environment open for help in terms of dysmenorrhoea and minimize the impact of menstrual pain on social and academic activities.
