Recording no known drug allergies

If a patient does not have any allergies or intolerances to medications, you should record this information in the patient’s chart. This way, it's easy to see if you haven't asked the patient about their allergies yet (Allergies section is empty) vs. you've asked them but they do not have any allergies. Also, when creating a prescription or recording an injection, you can see that the patient does not have any drug allergies.

Steps

1. In the patient's chart, from the Quick Menu or the Start/Open menu, click Allergies.

2. Select the No known drug allergies checkbox at the top of the section.

📌 Note: If drug allergies have already been recorded for this patient, the option for No known drug allergies does not appear.

The name of the user who selected the checkbox and the date appear next to the checkbox. In the patient summary, the NKDA indicator and the recorded date are displayed in the header of the Allergies section. The recorded date also appears next to the No known drug allergies checkbox in the injection window and the prescription window.

In the Allergies section of the chart, the button to add a new drug allergy disappears but you can still add non-drug allergies. See Recording patient allergies for more information.

💡 Tip: To view updates to the patient's allergies, click Open activity log in the blue banner at the top of the section.
