The MSD Manual Consumer app, developed by Merck Sharp Dohme LLC, is a user-friendly medical information platform designed for patients, caregivers, and families. This educational tool offers clear, practical explanations for a wide range of medical disorders, symptoms, diagnoses, and treatments. With content written and updated by over 350 medical experts, users can easily search for topics by symptom, diagnosis, or treatment in everyday language. The app includes thousands of photos, illustrations, and animations to visually demonstrate diseases and treatments, along with interactive quizzes, medical news, editorials, and self-assessments.

The app aims to provide accessible and accurate health information globally, without the need for registration, subscription, or encountering ads. However, internet access is required for some features like quizzes and news updates. The app is intended for use outside the United States, its territories, Puerto Rico, and Canada, and does not collect personal information.
