How to Say “I Am Allergic” in French

je suis allergique
To say "I am allergic" in French, use je suis allergique.
This phrase is a statement used to communicate that a person has a medical sensitivity to a specific substance.

Which one should you use?

While je suis allergique is the standard way to state an allergy, you can use Je réagis mal à to emphasize that you have adverse reactions to a particular allergen. For an informal way to say "I am allergic to that", you can use Je suis allergique à ça.

How does it change in a sentence?

The adjective allergique is invariable in gender, so it stays the same whether the speaker is male or female. When following je suis allergique with the substance you are allergic to, you must use the preposition à combined with the definite article: au, à la or aux.

What mistakes should you avoid?

Avoid using the preposition de when stating what you are allergic to. English speakers often mistakenly say "allergique de" instead of using à.

Did you know?

  • While allergique refers to medical sensitivities, the word allergie is sometimes used figuratively in French to describe a strong dislike or an instinctive aversion to a person or a situation.
  • The word suis in this phrase is a linguistic oddity. Its current form was heavily influenced by the Latin word for 'I was' rather than following the standard path for 'I am'.
  • When dining in France, speakers may use je ne supporte pas, meaning 'I cannot tolerate', to group medical allergies and digestive intolerances together.
