Objective: Children with food allergy need special care. Therefore, parents of food allergic children usually seek information on theinternet to improve their knowledge. However, the quality and accuracy of internet-based information may vary and misdirect parentsin their daily practices.Materials and Methods: We aimed to investigate the habits of internet usage in the families reporting cow’s milk protein allergy ormultiple food allergy in their children. This study was conducted by using a web-based questionnaire that can be completed on theInternet in Facebook groups of families who stated that their children had diagnosis of food allergy.Results: A total of 458 (96% female) individuals with a mean age of 32.03 ± 4.49 years participated in our survey. Three hundred fortythree (74.9%) participants reported that they have preferred the internet to get information associated with the complaints of theirchildren before seeing a physician. Two hundred ninty five (64.4%) participants reported that the information obtained on the internetand the information provided by the physicians were sometimes contradictory. As regards the contradicting information, 147 (49.8%)participants reported that they relied on the information provided by the physicians, whereas, 43 (14.9%) reported that they relied onthe information on the internet. In addition, 44.3% stated that they always or most of the time gave advice to other patients and theirfamilies on the internet.Conclusion: Considering that social media use is an unpreventable habit, online sources should include correct information forinformation-seeking parents and should possibly be supervised or be certified by health institutions and organizations.
