Caydra

Clinical AI for medication lists

Please remember: you are the clinician. Caydra helps expedite the review — it does not make the decision. Not a diagnosis. Not a prescription. Not a free-form chat. You enter the list.

A second check you can run yourself.

Many hospital systems already flag interactions inside the patient chart — Caydra is the standalone second check beside that: licensed clinicians enter the list, see colors and source notes when available, and keep their own judgment, with no hospital IT ticket. Clinician beta opened August 25, 2026 for the United States and Canada.

Three choices when a patient is on more than one medicine. Assistive only. It does not diagnose, treat, or prescribe. Not for patients.

U.S. emergency visits each year from adverse drug events (ADEs)

Almost 500,000

of those visits lead to hospitalization

Caydra does not claim to reduce these national figures. CDC defines an ADE as harm from a medicine (allergic reaction, side effect, overmedication, or medication error). Caydra assists licensed clinicians. It does not replace your judgment.

Critical Major Moderate Low Unknown

Caydra’s drug name list is built from RxNorm (U.S. National Library of Medicine): 14,000+ U.S. medication names clinicians can search. Source: NIH RxNorm. This describes our name list, not a claim that every drug pair has been scored. Methods and citations: Sources.

Built for the desk, not the install project

Independent and small-clinic clinicians in the United States and Canada can request the beta this month. Minutes, not months. You choose the list. You see why a color was assigned.

FDA label information on the same screen

Add a medication, then click its name. Caydra opens the FDA label: what it is used for, the dosage, warnings, and side effects, when that label is on file. If no label is on file, Caydra says so. That is not a finding that it is safe. The interaction colors stay separate. The clinician decides.

Colors so you can compare, not drown

Red is not mixed with mild noise. Gray means not in our evidence set yet - missing is not “safe.” If a color looks wrong, tell us. We review feedback and update when we can.

Please remember: You are the clinician. Caydra helps expedite your review — it does not make the decision. Do not rely on it alone. It does not diagnose, treat, or prescribe. Assistive software for licensed clinicians — not for patient self-treatment. Soft note: built as clinical support to assist your judgment; not offered as an FDA-cleared device that diagnoses or decides in your place. Caydra LLC is not your treating clinician.
