description: '**CHR:** Allergies and intolerances are recorded in the **Allergies** section of the patient chart, accessible from the patient summary or directly from the patient sidebar. Both drug and non-drug allergies can be entered.\n\n**MA:** Allergies and intolerances are managed via **Menu → Patients → select patient → Allergies → Add / select entry** (routes: `/DisplayCreateAllergy.do`, `/DisplayEditAllergy.do`). Drug allergies use the DIS drug catalog; non-drug allergies use free-text allergen entry. Confirmation status (Confirmed/Unconfirmed/Suspect/Refuted/Resolved/Erroneous) drives both FHIR clinicalStatus and verificationStatus.'
