Primary prevention
Prevention of drug-induced skin lesions is by avoiding the drug. Taking a history of drug allergy is important before any prescribing.
Secondary prevention
All adverse drug reactions need to be meticulously recorded and the patient fully informed.[60] Patients who have had an acute severe anaphylactic reaction should be given an adrenaline (epinephrine) pen for emergency use and taught how to use it properly. Ensure that information about drug allergy status (e.g., date of reaction, drug name [chemical and generic], route of administration, time interval between first dose and event, reaction type, and nature and severity of symptoms) is updated and included in hospital discharge letters and medical records. Links to photographs, results of any testing already performed, and management recommendations (e.g., safe alternatives or consideration for desensitisation) should also be included in health records where possible.[60] Patients should also be advised to wear a medical bracelet. Mobile apps are also available to help patients keep track of their allergies, which may help facilitate future communication with healthcare professionals.[60]
