Anaphylaxis is a severe allergy that can affect as much as 15% of the population. If the victim is unconscious, follow the basic steps of first aid. Look for several telltale signs that indicate an allergic reaction:
Itching
Redness
Hives (raised welts)
Scratchy throat
Dry mouth
Trouble breathing or wheezing
Dizziness
Weakness
It is not necessary to have all of the signs for it to be an allergy. If you suspect an allergic reaction and the victim has trouble breathing or dizziness, it is probably anaphylaxis.
Call 999 immediately if you suspect anaphylaxis.
