I am allergic to penicillin.
pe-ni-chil-LI-na — five syllables, stress on fourth. 'Penicillina' — the 'c' before 'i' is soft.
Always state this before any antibiotic prescription. Carry a card or note in Italian if you have this allergy.
'Sono allergico/a alla penicillina' uses 'essere' + 'allergico' (feminine: allergica). 'Alla' = to the (preposition di + article la contracted). Penicillin allergy affects about 10% of the population but true allergy is rarer — Italian allergologists can test with 'test di provocazione' (drug provocation test) to confirm.
Ho una grave allergia alla penicillina. Ho avuto anafilassi.
I have a severe penicillin allergy. I had anaphylaxis.
State severity — anaphylaxis history changes prescribing choices completely
Penso di essere allergico alle cefalosporine.
I think I am allergic to cephalosporins.
Cross-reactivity between penicillin and cephalosporins — about 1-2% true cross-allergenicity
Ho un'allergia documentata all'amoxicillina.
I have a documented allergy to amoxicillin.
'Documentata' = documented — mention if you have allergy test results
In Italy, drug allergy ('allergia ai farmaci') is documented in the patient's 'fascicolo sanitario elettronico' (electronic health record) and on the medical record. Italian allergologists ('allergologi') at 'centri di allergia' perform skin tests and provocation tests to identify true drug allergies. Penicillin 'allergy' is frequently over-reported — up to 90% of labelled penicillin-allergic patients can safely receive penicillin after proper testing.
