What is Epocrates?
Epocrates is a mobile drug reference app for clinicians, launched in 1998 and now owned by athenahealth. Its free app covers drug monographs and dosing, a multi-drug interaction checker, pill identification and formulary information, and it lists 600+ medical calculators (vendor figure). Epocrates and athenahealth report more than 1 million healthcare professional users.
Epocrates is built for quick checks on a phone at the point of care. The desktop web version is secondary to the iOS and Android apps, and Epocrates Plus adds disease content, diagnostic tools and lab references for clinicians who want more than drug information.
Is Epocrates free?
Epocrates has a free basic app that needs only registration and covers drug monographs, interaction checks and pill identification. Epocrates Plus, also written Epocrates+, costs $179.99 a year according to Epocrates’ pricing page, checked October 26, 2026, and adds disease content, diagnostic tools and lab references. No resident discount is listed.
Plus costs less than the main paid references: one US UpToDate subscription is $579 a year and DynaMed starts at $399 (October 2026). Those go deeper on disease management, and many clinicians already get UpToDate or DynaMed through an employer, so check before paying for Plus for disease content.
What does Epocrates Plus include?
Epocrates Plus includes everything in the free app and adds disease and diagnostic content, lab reference guides and, as of October 2026, an AI Assist beta. It costs $179.99 a year. The disease content works for quick reminders but is shallower than UpToDate or DynaMed, so it does not replace a full clinical reference.

Does Epocrates have AI?
Epocrates’ free app has no natural-language search, AI clinical reasoning or evidence synthesis: you look up drugs and run checks yourself. Epocrates Plus lists an AI Assist beta on its product page, checked October 26, 2026. Epocrates has no ambient scribe or differential diagnosis generator, so clinicians who want cited AI answers pair it with a dedicated AI tool.
Because AI Assist is labeled a beta, check what it covers and which sources it cites before relying on it.
OpenEvidence gives cited answers but has no drug dosing tools, so the two work well together. Vera Health combines cited answers with its own drug database, interaction checks and 900+ calculators (vendor figure), and is free for licensed clinicians and trainees.
Does Epocrates have a drug interaction checker?
Epocrates includes a free multi-drug interaction checker: you add drugs to a list and it flags conflicts by severity. It sits beside drug monographs, dosing and a camera-based pill identifier in the free app, built for quick checks on a phone. Interaction results still need clinical judgment, especially for complex regimens.
The checker suits ICU polypharmacy and multi-drug antimicrobial regimens. The free app has no natural-language search, so questions about why a combination matters belong in a reference or an AI answer tool.

How Epocrates compares
Epocrates is a drug reference rather than an AI answer tool, so it is usually weighed against tools that add cited answers or deeper disease content. Several of them include drug information too.

How Clinical AI Report rates Epocrates
63/100
#6 of 7 general clinical decision support tools
Epocrates earns a Fair rating for doing one thing well: fast, reliable drug reference at the point of care. The free tier is genuinely useful, and the mobile app is well-designed. But the absence of AI clinical reasoning, differential diagnosis, and evidence synthesis features limits its utility as a standalone decision support tool.

Epocrates FAQ
Does Epocrates integrate with an EHR?
