藥物過敏與副作用英文：如何清楚告訴醫師和藥師

把「過敏」和「副作用」講混，是英語就醫時最容易出包的地方之一。Allergy 是免疫系統反應，可能很危險（疹子、腫脹、呼吸困難）；side effect 是藥物本身常見的反應（頭暈、想吐、口乾），通常停藥就好。醫師聽到「I'm allergic to X」會直接把那個藥從你終身選項中拿掉；聽到「It made me dizzy」則會考慮換劑量或換時間吃。把兩者分清楚，醫師才能做正確的決定。

本文僅教英文溝通，不提供醫療診斷或治療建議；如果懷疑過敏反應正在發生（呼吸困難、臉部腫脹、全身蕁麻疹、意識改變），請立即停藥並撥打當地急救電話。

Allergy vs side effect — 一句話分清楚

你的狀況 該怎麼講
吃 penicillin 會長蕁麻疹 I'm allergic to penicillin. I get hives.
吃 amoxicillin 第一天輕微頭暈 Amoxicillin made me a little dizzy on day one.
吃止痛藥之後嘴唇腫起來 I had a reaction to that pain reliever — my lips swelled up. I'm allergic to it.
吃感冒藥昏昏欲睡 The cold medicine made me drowsy.
吃抗生素拉肚子 The antibiotic gave me diarrhea. (side effect)
接種顯影劑後喘不過氣、起紅疹 I had a serious reaction to the contrast dye — I'm allergic.

錯誤說法 vs 自然說法

不太自然 自然好用 為什麼
I cannot eat penicillin. I'm allergic to penicillin. 「不能吃」太籠統，醫師需要知道是過敏。
I have side effect allergy. I had a reaction — I think it was an allergy, not a side effect. side effect 和 allergy 要分開講。
Medicine make my body itchy. The medication made me itchy all over. / I broke out in itching. 用 made me + 形容詞。
My face big after take. My face swelled up after I took it. swelled up 是固定搭配。
Stomach not good after eat medicine. It gave me an upset stomach. 用 gave me + 症狀。
I die almost. I had a severe reaction; I had to go to the ER. 不要用誇張詞，說明嚴重程度即可。
I no like this medicine feel. I didn't tolerate it well — it made me [side effect]. 用 didn't tolerate it well 比較準確。

情境對話：藥師發現過敏疑慮

Pharmacist: I see your prescription is for amoxicillin. Do you have any drug allergies? （藥師：你的處方是 amoxicillin，有藥物過敏嗎？）

You: Yes, I'm allergic to penicillin. Last time I took it I broke out in hives all over my arms and chest, and my lips swelled a little. （你：有，我對 penicillin 過敏。上次吃後手臂跟胸口長滿蕁麻疹，嘴唇也有點腫。）

Pharmacist: Amoxicillin is in the same family as penicillin, so it's not safe for you. Let me call the doctor and ask for an alternative. （藥師：amoxicillin 跟 penicillin 同類，所以不適合你。我打電話給醫師請他換一個。）

You: Thank you. Could you also note this in my file so it doesn't come up again? （你：謝謝。可以順便把它記在我檔案裡嗎？這樣以後就不會再開了。）

Pharmacist: Of course. By the way, the new prescription might cause some nausea — that's a side effect, not an allergy. Take it with food and it usually helps. （藥師：當然。順帶一提，新藥可能會有點噁心，那是副作用不是過敏，隨餐吃通常會緩解。）

You: Got it. If the nausea is really bad or if I get any rash, I'll call you right away. （你：好。如果噁心很嚴重，或是長疹子，我會馬上打給你。）
