Severe episodes, however, may go on for days or even weeks. Mild attacks can resolve spontaneously or may require medication. More severe attacks can also be treated with medications but may require hospitalization. Always follow the instructions of your allergist. In general, it is important to stay calm and take your prescribed medications.
Bronchodilators are the most commonly prescribed drugs to treat asthma.
They relax the muscles surrounding the airways, resulting in dilation of the bronchial tubes. Bronchodilators may be inhaled, taken orally or injected. During exercise, rapid breathing occurs through the mouth. As a result, the air which reaches the bronchial tubes has not been warmed and humidified by passing through the nose. This cold, dry air can trigger asthma.
