Inhaled steroids are not the only steroids for asthma: Oral steroids, also called systemic corticosteroids, are often used when you develop an asthma exacerbation or attack. This form of steroids for asthma is different from inhaled steroids because it affects the whole body.
Corticosteroids reduce inflammation of the airways to help prevent asthma symptoms and attacks. Corticosteroids are often referred to with the abbreviated name of “steroids” and should not be confused with the drugs that are abused by some athletes, which are a different type of compound often involving the synthetic male hormones.
Anti-inflammatory asthma inhalers are often used as a first-line controller treatment for asthma. After introduction of inhaled steroids, the need for oral steroids such as prednisone may decrease.
