Objectives: Today's general trend of growing consumption of herbal drugs and dietary supplements, as part of self-medication, has not bypassed even pregnant women. Although the prevailing opinion is that such preparations are safe and harmless, their improper use without professional supervision carries a certain risk for mother and child. Therefore, the aim of this research is to examine the attitudes of pregnant women in Croatia regarding the use of herbal drugs and dietary supplements and their experiences related to the use of such preparations during pregnancy. Respondents and Methods: In this work, a survey was conducted using an anonymous questionnaire on a sample of 110 adult pregnant women. At the beginning of the questionnaire, sociodemographic data on pregnant women were collected. Data were then collected on pregnancy, dietary and lifestyle habits during pregnancy, and chronic diseases and other health problems. The remaining questions examined the attitudes and experiences of pregnant women regarding the use of herbal drugs and dietary supplements during pregnancy. The research was conducted in public pharmacies in Croatia and one gynecological polyclinic in Zagreb in the period from September 2020. to February 2021. Results: Almost two-thirds of the respondents (73 %) used some herbal drug or dietary supplement during pregnancy, and their use increased compared to before pregnancy. Most pregnant women took vitamin-mineral preparations (89 %) and phytopreparations (56 %). Almost all pregnant women bought the used preparations in a pharmacy, but the fact that only half (53 %) received professional information related to their use is worrying. Every fourth pregnant woman uses herbal drugs and/or dietary supplements for some health problem, while 79 % of them use such preparations to strengthen their health. Pregnant women most often took these preparations as recommended by gynecologists (56 %) or pharmacists (40 %). More than 75 % of respondents believe that every pregnant woman should take folic acid, vitamins, minerals and omega 3 fatty acids independently of her diet. Regarding the effective and safe use of phytomedicines, as well as the quality of herbal drugs and dietary supplements, pregnant women showed some uncertainty. It is encouraging that 76 % of pregnant women believe that herbal medicines and nutritional supplements should be dispensed exclusively in pharmacies, but about 25 % believe that gynecologists and pharmacists do not have enough knowledge to provide quality advice on the use of such preparations during pregnancy. Two thirds of the respondents expressed the need for professional training for pregnant women in this area. Conclusion: A high rate of use of herbal drugs and dietary supplements during pregnancy was found. By using such preparations, pregnant women most often want to additionally enrich their usual diet and/or influence the improvement of symptoms of various health problems caused by changes during pregnancy. In order to ensure the effective use of herbal drugs and dietary supplements and to prevent possible unwanted consequences due to selfmedication, the involvement of educated health professionals, especially doctors and pharmacists, is necessary.
