Inhaled corticosteroids are the most effective medications for asthma.
They help decrease the frequency of asthma attacks and lower the dosage of other medications needed to relieve symptoms. The risk is greater with higher doses and longer use. The key is to use the lowest possible effective dose of corticosteroids. If you use inhaled corticosteroids, use a spacer and gargle with water after use to rinse your mouth out. It's important to then spit out this water.
