过敏反应就诊

OK, I need you to stay calm. Are you having any trouble breathing? Any tightness in your throat or chest?

I'm going to give you an antihistamine — Benadryl — right away. That should help with the swelling and itching. Have you ever had a shellfish allergy before?

It's possible — some people react to specific types of shellfish. I'm also going to prescribe an EpiPen for you to carry. If you ever feel your throat closing or have trouble breathing after eating, use it immediately and call 911. This is important.

Yes, we can do a skin prick test. We'll apply small amounts of common allergens to your forearm and see which ones cause a reaction. It takes about 30 minutes for the full test. You'll need to stop taking antihistamines at least 3 days before the test.

Yes, let's do it now. I'll test for the most common ones — tree pollen, grass pollen, ragweed, dust mites, mold, pet dander, and several food allergens. You'll feel small scratches, like a mosquito bite.

Depending on the results, I can recommend daily antihistamines, nasal corticosteroid sprays, or for long-term relief, immunotherapy — which is allergy shots or sublingual tablets that gradually reduce your sensitivity over time.

Absolutely — let's practice right now with a trainer pen. Here's the thing: it's designed to be simple. Step one: pull off the blue safety cap — 'blue to the sky.' Step two: press the orange tip firmly against your outer thigh — 'orange to the thigh.' You can inject through clothing, no need to roll up your pants. Hold it for 10 seconds. Step three: call 911 immediately after. Even if you feel better, the reaction can come back. That's called a biphasic reaction.

Yes, check the window on the pen — there's an expiration date printed there. If the liquid looks clear, it's still good. If it's cloudy or brownish, don't use it — get a replacement right away. Typically they last about 12 to 18 months. Set a reminder on your phone so you don't forget to refill the prescription before it expires.

Great idea. I'll refer you to an allergist — Dr. Patel in our network. She can do a skin prick test and a blood panel called a specific IgE test. The skin prick test covers about 40 common allergens — foods, pollens, pet dander, dust mites. Results in about 20 minutes. The blood test is more comprehensive and can test for over a hundred allergens. Between the two, we'll get a very clear picture of your triggers.

Absolutely — I strongly recommend it, especially since you're traveling abroad. If you ever have a severe reaction and can't speak, the bracelet tells paramedics exactly what you're allergic to. You can get ones that say 'Severe Shellfish Allergy — EpiPen Carrier' with your emergency contact. You can order them online — MedicAlert and Road ID are popular brands. Some are quite stylish now — they look like regular jewelry. I'll also give you a written allergy action plan card to keep in your wallet. It lists your allergens, medications, and emergency steps in both English and Chinese.
