Background and aim. Adverse drug reactions (ADRs) are common events in medical practice, representing a matter of concern for both outpatient and in hospital care. Understanding and management of ADRs depend on their mechanism and clinical picture, which are complex and highly heterogeneous. Drug hypersensitivity reactions (DHRs) are immunologically-mediated ADRs, which are considered allergies after demonstrating evidence of either drug-specific antibodies or T-cells. The correct diagnosis of a drug allergy in hospital setting is essential for the outcome of treated disease and for the patient future in terms of therapeutic needs. Patients may be labeled as being drug allergic, based on their history and vague symptoms that do not correspond to a true allergic reaction. The aim of our study was to evaluate consequences of drug allergy labelling of female patients hospitalized in the department of obstetrics and gynecology from a university hospital during one year, in terms of medical attitude and therapeutic approach. Method and Results. We found that 159 out of 2395 patients hospitalized in the obstetrics-gynecology department declared a history of drug allergy on admission, but only 3 patients had medical documents and adequate recommendations from the allergist. Hospital medical attitude was significantly influenced in all declared allergic patients, mainly in terms of antimicrobial and anti-inflammatory therapy. Conclusion. We concluded that overestimation of drug allergies in hospital care has important consequences in terms of current and future recommended therapy that should be based on standardized allergist evaluation. Keywords: drug allergies, hospital setting, patient’s history, therapeutic errors.
