An allergic reaction could quickly affect your ability to breathe, so call 911 or go to an emergency room immediately if you have hives accompanied by hoarseness or wheezing, swelling in your
tongue or face, tightness in your throat, fainting, or if you develop hives on your
tongue. You may need immediate medical attention if you experience cold sweats, nausea, dizziness, or trouble breathing after a bee sting, an insect bite, eating a meal, or taking medicine.
