Inhaled corticosteroids (ICS)

Anti-inflammatory drugs used for long-term control of asthma. They reduce swelling and tightening in your airways, and reduce the risk of having severe attacks or dying of asthma. For the best outcomes, ICS-containing controller treatment should start as soon as possible after the diagnosis of asthma. These medications start working quickly but you may need to use them for several months before you get their maximum benefit. Regular use of ICS helps keep asthma attacks and other problems linked to poorly controlled asthma in check. Inhaled corticosteroids act directly in the airways, and they have fewer side effects than oral corticosteroids.
