About Evidence Health
A medicine information site that only says what official sources say, and shows you where each statement came from. It is built for patients and carers who want to understand their medicines before talking to a doctor or pharmacist.
Why it exists
People now ask AI about their medicines every day, and a general chatbot answers just as confidently when it is wrong.
For a dose, a warning or a reason not to take something, a fluent wrong answer is worse than no answer. Chatbots can also invent studies and citations that look real.
Evidence Health turns this around. The evidence comes first: official labels and records, stored with their versions and dates. The AI only explains what that evidence says, and every point links back to its source.
How it differs from a general chatbot
The same question, two very different ways of answering it.

What works now, and what’s next
We mark the difference instead of implying everything is ready.
Where the data comes from
Everything in the library comes from U.S. government sources that are free to use: the FDA (labels, recalls, product listings and side-effect reports), and the National Library of Medicine (RxNorm medicine names, MedlinePlus condition guides and PubMed study records).
Condition explanations are courtesy of MedlinePlus. From PubMed we store only a study’s title, journal and date, and link to the original.
Your information
You can use the whole site without an account. If you create one to save your medicines, that list is private to you and is never used to train AI models.
Questions you ask are sent, with the matching label passages, to an AI provider to write the answer. Don’t include your name or other personal details in a question.
Honest limits
This is an information tool, not a medical device and not a substitute for care. It covers a starter set of common medicines and U.S. sources only. Reported side effects are signals from spontaneous reports, not how often something happens. Confirm anything important with your doctor or pharmacist. See how it works →
