First Aid FAQ's

How long does anaphylaxis last if treated?

With a rapid response, anaphylaxis can often improve within a few hours with no long-lasting consequence. Severe cases may take several days to resolve, particularly if the person has a pre-existing condition like COPD, chronic kidney disease, or heart failure.

In cases like these, anaphylaxis can cause irreversible organ damage if not treated quickly and appropriately.
