4. Common Causes of Severe Allergic Reactions

Anaphylaxis can be triggered by many different factors, including:

• Foods (peanuts, shellfish, milk, eggs)
• Medications (antibiotics, pain relievers)
• Insect stings (bees, wasps)
• Latex or environmental allergens

Sometimes people are aware of their allergies. In other cases, this may be the first time symptoms appear.

5. Why Immediate Action Matters

One of the biggest dangers is waiting too long.

Many people assume:

“It’s just a rash”
“It will go away on its own”

But once breathing is affected, the condition can worsen rapidly. Severe reactions can lead to airway blockage, shock, or even loss of consciousness if not treated quickly.

6. What To Do Right Away

If someone has hives and difficulty breathing:

• Call emergency services immediately
• Use an epinephrine auto-injector (EpiPen) if available
• Keep the person lying down (unless breathing worsens)
• Monitor closely until help arrives

Do not delay treatment.

7. Could It Be Something Else?

Not all skin rashes are dangerous. Conditions like:

• Mild allergic reactions
• Skin irritation
• Infections
• Chronic hives can also cause red patches.
