Purpose of study Cystic fibrosis (CF) is a complex genetic disease with high mortality, of which 85% is a result of lung disease characterized by serious endobronchial infections. Recent findings Antibiotic therapy is one of the main treatments of CF, both during acute exacerbations and as chronic maintenance medications, contributing to a prolonged survival. Since neonatal CF screening programs have been implemented universally and the longevity of patients with CF steadily increases, antibiotic hypersensitivity reactions (HSRs) are becoming more important. HSR to antibiotics in CF has been reported since the 1980s andwas estimatedtooccuruptothree timesmorefrequently inthese patients, probably owing to high rates of antibiotic exposure and boosting stimuli such as infections and inflammation. However, recent studies including large groups of CF patients with a suspicion of antibiotic allergy have used diagnostic algorithms including skin tests and drug provocation tests and showed that true incidence was much lower. The mechanism of the reactions and the clinical presentations are not different in CF than in the general population. Both the immediate and nonimmediate type HSRs are seen, and among the latter, drug fever and drug-induced hemolytic anemia are distinctive presentations. Beta-lactam (BL) agents are the most common cause, with higher rates for
