Drug Allergy
Key Points
Key Points
- Significant new information and recommendations update the 2010 drug allergy practice parameter.
- There is an overall de-emphasis on the use of skin testing as compared with drug challenge.
- More emphasis is placed on risk stratification based on reaction phenotype.
- When clinical probability of drug allergy is low, 1- or 2-step drug challenges are the preferred evaluation.
- For patients with reported penicillin allergy, proactive efforts should be made to delabel and also avoid unnecessary avoidance of non-cross reactive antibiotics.
- Consideration of phenotypes for adverse reactions to various non-antibiotic drugs (NSAIDs, biologics) should be used to guide evaluation and management.
