Objectives: The research aimed to examine the availability and quality of information on the use of medicines, nutritional supplements and cosmetic products by pregnant women. Material and methods: To obtain data on medicines, nutritional supplements and cosmetic products, research was performed on the websites Amazon.com (Amazon.com, Inc, 2021) and Online Pharmacy Coner. The searched products had to contain acetylsalicylic acid, passionflower or retinol. Results: The results of the research revealed that the term pregnancy was mentioned in one of the twenty medicines containing acetylsalicylic acid. A significant difference was obtained regarding the information on the use of passiflora by pregnant women, with information on the Coner website listed in 55 % of the products, while 20 % of the products contained such information on the Amazon website (p<0.001). Finally, for searched medicines, it was determined there is no information about its use depending on the trimester of pregnancy and contraindications in pregnancy, as well as possible interactions with other conditions and medicines. Conclusion: The conducted research indicates the low availability and quality of information about the use of medicines, nutritional supplements and cosmetic products by pregnant women. The highest level of information and advice for this special group of patients can be provided by a pharmacist in a pharmacy. The online way of shopping and researching medicines, nutritional supplements and cosmetic products should be carefully considered by pregnant women because the quality of information provided on online sites is still not at a level that can confirm the safe use of the product.
