Remove Allergy Event

Last updated: 1 Sep 2026

Introduction #

The RemoveAllergyEvent model represents a record of an allergy being removed from a patient’s allergy list — the anchor for the Remove Allergy command.

Basic usage #

To get a remove allergy event by identifier, use the get method on the RemoveAllergyEvent model manager:

from canvas_sdk.v1.data import RemoveAllergyEvent

removal = RemoveAllergyEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")

If you have a patient object, the remove allergy events for a patient can be accessed with the removed_allergies attribute on a Patient object:

from canvas_sdk.v1.data.patient import Patient

patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
removals = patient.removed_allergies.all()

The same records are reachable from the note they were recorded on, with the removed_allergies attribute on a Note object:

from canvas_sdk.v1.data.note import Note

note = Note.objects.get(id="89992c23-c298-4118-864a-26cb3e1ae822")
removals = note.removed_allergies.all()

You can also access the removed allergy with the allergy attribute:

from canvas_sdk.v1.data import RemoveAllergyEvent

removal = RemoveAllergyEvent.objects.get(id="61a1853f-168f-4ed3-80d2-44e5d144bcf3")
allergy = removal.allergy

Or for a given allergy, you can access all of its removal events with the remove_allergy_events attribute:

from canvas_sdk.v1.data import AllergyIntolerance

allergy = AllergyIntolerance.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
removals = allergy.remove_allergy_events.all()

Committed records #

The committed method returns remove allergy events that have been committed and not entered in error:

from canvas_sdk.v1.data import RemoveAllergyEvent

committed_removals = RemoveAllergyEvent.objects.committed()
