Medscape Reference is the most authoritative and accessible point-of-care medical reference for physicians and health care professionals. All content is available free of charge, both online and via mobile devices.

Medscape Reference articles represent the expertise and practical knowledge of top physicians and pharmacists from leading academic medical centers in the US and worldwide. In addition, our rigorous literature survey process allows us to rapidly integrate new practice-changing information into the relevant topics by systematically reviewing the major medical and pharmacy journals, news announcements, and important practice guidelines.

Medscape Reference provides comprehensive coverage across more than 30 medical specialties and is composed of the following areas:

More than 6,300 evidence-based and physician-reviewed disease and condition articles are organized to rapidly and comprehensively answer clinical questions, as well as to provide in-depth information in support of diagnosis, treatment, and other clinical decision-making. Topics are richly illustrated with more than 30,000 clinical photos and radiographic images.

More than 650 clinical procedure articles provide clear, step-by-step instructions, and include instructional videos and images to allow clinicians to master the newest techniques or to improve their skills in procedures they have previously performed.

More than 2,100 monographs, including prescription and over-the-counter drugs, plus over 5,000 corresponding brand-name drugs, herbals, and supplements, are provided. Drug images and pricing are also included. In addition, a Drug Interaction Checker provides rapid access to tens of thousands of interactions between brand and generic drugs, over-the-counter drugs, and herbals and supplements.

More than 70 anatomy articles feature clinical images and diagrams of the major human body systems and organs. The articles assist with the understanding of the anatomy involved in treating specific conditions and performing procedures. They can also facilitate physician-patient discussions.

This email newsletter features current and clinically relevant journal citations that are selected via our rigorous literature survey review process. These same citations are incorporated into the relevant Medscape Reference articles. This newsletter serves as a quick and easily accessible way to stay up to date with clinically relevant journal articles that impact clinical practice.

These challenging and classic case presentations provide a quick way for practicing physicians to sharpen their diagnostic and patient-management skills. Each case starts with how the patient presented in the clinic and then using a question and answer format, progresses through diagnosis and on to treatment and includes follow up information about outcome for the patient.

Image collections are a visually-engaging presentation of both common and uncommon diseases, case presentations, and current controversies in medicine. They are presented in an image rich, slideshow format and are designed to challenge and expand physicians' knowledge of clinically important topics.
