[Asthma exacerbations in adults: Preventing and treat].

Exacerbations of asthma are still responsible for 900 deaths per year in France, most of which are considered preventable. They have a major impact on the quality of life of patients and are responsible for a large part of the socio-economic cost of asthma in France. Exacerbations of asthma can be partly prevented by inhaled corticosteroid treatment as controller therapy, at a dose adapted to the level of control of symptoms and the management of aggravating factors. Every patient should benefit from a written action plan that allows them to start oral corticosteroid therapy as soon as possible during an exacerbation. The treatment combines short-acting bronchodilators with systemic corticosteroids. Systemic antibiotic therapy has no place in the treatment of exacerbations. The patient must be seen early in the course of an exacerbation of asthma to review all of his follow-up.
