Alergias a medicamentos y efectos secundarios en inglés: cómo explicárselo claramente a médicos y farmacéuticos

Alergias a medicamentos y efectos secundarios en inglés: cómo explicárselo claramente a médicos y farmacéuticos

Confundir "allergy" y "side effect" es una de las maneras más fáciles de despistar a un clínico de habla inglesa. Una alergia es una reacción del sistema inmunitario y puede ser peligrosa — sarpullido, hinchazón, dificultad para respirar. Un efecto secundario es una reacción conocida a un fármaco (mareo, náuseas, sequedad de boca) que normalmente desaparece cuando dejas de tomarlo. Cuando un médico oye "I'm allergic to X", retira ese fármaco de tus opciones de por vida. Cuando oye "It made me dizzy", quizá solo ajuste la dosis o cambie cuándo lo tomas. Distinguirlos con claridad permite que el clínico tome la decisión correcta.

Este artículo enseña comunicación en inglés para situaciones de atención sanitaria. No es un diagnóstico ni un consejo de tratamiento médico. Si sospechas que está ocurriendo una reacción alérgica (dificultad para respirar, hinchazón facial, urticaria generalizada, alteración de la consciencia), detén el medicamento y llama de inmediato al número local de emergencias.

Diálogo situacional: un farmacéutico detecta un problema de alergia

Pharmacist: I see your prescription is for amoxicillin. Do you have any drug allergies?

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.

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.

You: Thank you. Could you also note this in my file so it doesn't come up again?

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.

You: Got it. If the nausea is really bad or if I get any rash, I'll call you right away.
