Objective: The aim of this study was to evaluate health-related tweets on Twitter for validity (evidence based) and to create awareness in the community regarding the importance of evidence-based health-related tweets. Methods: All tweets containing health-related information in the Arabic language posted April 1-5, 2015, were mined from Twitter. The tweets were classified based on popularity, activity, interaction, and frequency to obtain 25 Twitter accounts (8 physician accounts, 10 nonofficial health institute accounts, 4 dietitian accounts, and 3 government institute accounts) and 625 tweets. These tweets were evaluated by 3 American Board--certified medical consultants and a score was generated (true/false) and interobserver agreement was calculated. Results: A total of 625 health-related Arabic-language tweets were identified from 8 physician accounts, 10 nonofficial health institute accounts, 4 dietician accounts, and 3 government institute accounts. The reviewers labeled 320 (51.2{\%}) tweets as false and 305 (48.8{\%}) tweets as true. Comparative analysis of tweets by account type showed 60 of 75 (80{\%}) tweets by government institutes, 124 of 201 (61.7{\%}) tweets by physicians, and 42 of 101 (41.6{\%}) tweets by dieticians were true. The interobserver agreement was moderate (range 0.78-0.22). More than half of the health-related tweets (169/248, 68.1{\%}) from nonofficial health institutes and dietician accounts (59/101, 58.4{\%}) were false. Tweets by the physicians were more likely to be rated ``true'' compared to other groups (P<.001). Conclusions: Approximately half of the medical tweets from professional accounts on Twitter were found to be false based on expert review. Furthermore, most of the evidence-based health-related tweets are posted by government institutes and physicians.
