Avoid when
You say "我对这个过敏" (wǒ duì zhège guòmǐn). It literally means "I towards this allergic" and is used when pointing at the specific item.
It is pronounced "wǒ duì zhège guòmǐn". Pay attention to the tones: wǒ (3rd tone), duì (4th tone), zhè (4th tone), ge (neutral), guò (4th tone), mǐn (3rd tone).
Use it in medical situations, like at a doctor or pharmacy, when you need to indicate that you are allergic to a specific item you are pointing at. It is direct and appropriate for such contexts.
