Recent studies estimated that between 30 to 50% of the population does not adhere to the prescribed therapies, and one of the reasons is pharmacophobia. Pharmacophobia is a fear of medication and a negative attitude towards drugs in general. The aim of this study was to determine predictors of fear of taking medication, in other words pharmacophobia. 700 participants participated in the study participated, of which 80.9 % was female. The age of the participants ranged from 19 to 62 years (M = 26.5, SD = 7.41). The instrument consisted of several questionnaires that have been evaluating: history of health problems, frequency of medication usage, attitude towards drug, beliefs about medicine, emotional disgust, tendency to alternative medical habits and the likelihood of believing the conspiracy theories. Also, the demographic data was collected. The research was conducted through an online Google Forms survey which was set up on social networks and sent to student mailing groups. Likewise, the survey was also sent directly to potential participants. The results showed that out of the total number of participants, 20.3% estimated that they were pharmacophobic, and the other 79.7% of participants estimated themselves as pharmacophilies. Given to the goal of the study, obtained results suggest that one of the predictors of pharmacophobia is tendency of believing in conspiracy theories, where the higher inclination to believe in conspiracy theories is leading to greater pharmacophobia. Furthermore, the preference of solid drug forms and drugs that are intended for the usage through the body cavity, also contribute to the explanation of pharmacophobia in a way that pharmacophobic persons do not have preference toward said medication forms. The predictor who contributes the most in the explanation of pharmacophobia is a negative belief in drugs, suggesting that a person with expressed negative attitude to medication will probably not even adhere to the prescribed therapies by the doctors.
