Hypersensibilité aux médicaments.

Although true allergic drug hypersensitivies are rare, adverse reactions to drugs are common and affects the entire population, regardless of age. Often unexplored, it involves significant morbidity, which could be avoided by carrying out a pharmacovigilance investigation and an allergological work-up. Clinical symptoms of drug hypersensitivity depend on the time to the first symptoms after exposure to the drug and the different immune or pharmacological responses involved. The management of the reaction and the allergological assessment depends on these physiopathological mechanisms and the severity of the reaction. [ABSTRACT FROM AUTHOR]
