Anaphylaxis is a severe allergy that can affect as much as 15% of the population. If the victim is unconscious, follow the basic steps for 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
Call 911 immediately if you suspect anaphylaxis.
