Call emergency services immediately for trouble breathing, throat or tongue swelling, fainting, collapse, or other signs of anaphylaxis.
Use prescribed epinephrine without delay according to the person’s emergency plan.
And for anyone, someone who:
Seek urgent medical advice for rapidly increasing swelling, repeated vomiting after a likely allergen exposure, worsening wheezing, or symptoms that return after initial improvement.
Arrange routine follow-up after a suspected allergic reaction, even if symptoms have resolved.
The visit can clarify the likely trigger, determine whether testing is useful, and update the medical record.
After anaphylaxis, follow-up with a clinician or allergy specialist is particularly important.
The visit may include reviewing epinephrine technique, replacing used or expired devices, creating an action plan, and discussing ways to reduce future exposure.
Seek routine medical advice if reactions keep happening, the trigger is unclear, a rash persists, or allergy symptoms interfere with sleep, school, work, diet, or asthma control.
Medication allergies should be documented with the specific medicine, symptoms, timing, and date rather than simply listing “allergy” without details.
