Corticosteroids are anti-inflammatory drugs that work over an extended period of time to lessen inflammation in the lungs. These medications are available in a variety of forms.Most can be taken through metered-dose inhalers, dry powder inhalers, or nebulizers, which deliver the medication in a very fine mist. Corticosteroids can also be prescribed in the more traditional pill or syrup form. Oxygen therapy is often used to supplement medication and involves supplying fresh oxygen directly to the patient. This therapy may be prescribed if appropriate levels of oxygen are not reaching the blood. Supplemental oxygen can help patients sleep better, complete daily activities with less difficulty, and even prolong their lives!
