A drug the patient is allergic to
A patient is recorded with a Penicillin allergy. The doctor types "Amoxicillin 500mg" in the prescription. The medicine name input turns rose, an inline chip says "Patient is allergic to Penicillin · severe", and a banner at the top of the tab lists every conflict. The match is class-aware — typing "augmentin" or "ampicillin" triggers the same warning.
