When should I call 911 about hives?

ANSWER

1. You start to get burning or itchy welts in your throat.

2. You get hives and a dry throat, cough, cold sweats, nausea, dizziness, trouble breathing, or a sharp drop in blood pressure after a bee sting or insect bite or a new medication. This may be anaphylaxis. Give yourself an epinephrine shot. You still need medical attention after the shot.

3. Your lips, tongue, or throat are swollen. You need immediate medical attention so that the swelling doesn’t block the air passage to the lungs.
