Tightness in the chest and difficulty in breathing. Hoarse voice or swelling of the tongue. Dizziness or a sharp drop in blood pressure. Unconsciousness or cardiac arrest. This type of reaction can occur within minutes after the sting and may be life-threatening.
Avoidance is the key.
The first rule when a bee approaches is to stay still. It will not sting unless frightened or antagonized. Remain calm and gently brush it away. Caution children about not throwing stones or sticks at insect nests. Highly allergic patients should obtain a prescription for self-administered Epinephrine.
