What causes sudden episodes of swelling in the throat despite taking an antihistamine?
Patient: Since last fall, certain things trigger my throat to swell. No runny nose, itchy eyes, hives, difficulty breathing though. Car exhaust, garages, musty leaves or crawl spaces, cleaning agents, bleach, fabric softener, perfumes, sometimes a dog that has a skin treatment. Doctor recommended an antihistamine. I took one, one day last week, then a few hours later went to an enclosed swimming pool. Within 5-10 minutes, my throat swelled and my throat was covered in little white bumps. Doctor is on vacation. We talked about an allergist. I was checking out allergic reactions on this site and nothing seemed to fit my symptoms. Doctor: Hello,You might be having hypersensitivity. You need to get complete blood count done to see if there is eosinophilia in blood. In people with allergy generally there will be eosinophilia. In that case, you need to take a course of Benocide Forte or Hetrazan tablet 3 times a day for 2 weeks. This will bring down allergic reactions. Kindly discuss this with your doctor. Till then just avoid whatever things that is causing you allergy.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Sanjay Kini
