• Difficulty breathing or wheezing
• Hives or itchy rash
• Nausea, vomiting, or diarrhea
• Dizziness or loss of consciousness
• Rapid heartbeat
• Drop in blood pressure

What to Do:

1. Administer Epinephrine: If you have a known allergy and carry an epinephrine auto-injector (EpiPen), use it immediately.
2. Call 911: Even after using epinephrine, it’s crucial to seek emergency medical attention. Anaphylaxis can be biphasic, meaning symptoms may return hours later.

1.2 Mild Allergic Reactions

Milder allergic reactions can also cause throat swelling, though the symptoms are typically less severe than in anaphylaxis.

Symptoms of Mild Allergic Reactions:

• Itching or tingling in the mouth
• Mild swelling of the lips, tongue, or throat
• Hives or rash
• Nasal congestion or runny nose
• Watery eyes

Management:

• Antihistamines: Over-the-counter antihistamines like diphenhydramine (Benadryl) or loratadine (Claritin) can help relieve mild allergic symptoms.
• Avoid the Allergen: Identify and avoid the substance causing the reaction.
• Monitor Symptoms: Watch for any signs of worsening and seek medical attention if necessary.

2. Infections Causing a Swollen Throat

Infections, particularly those affecting the throat and tonsils, are common causes of a swollen throat.
