One of the most effective medications for controlling asthma is inhaled corticosteroids, which are anti-inflammatory medications. Taken early and as directed, these well-tolerated and safe medications can improve asthma control and normalize lung function. Immunotherapy or allergy shots should be considered if asthma is triggered by exposure to unavoidable allergens, or if symptoms occur three days a week and more than two nights a month.

The shots are especially helpful when symptoms occur year-round or are not easily controlled with medication. Allergists are the medical specialists with the most expertise in treating asthma. An allergist can find the source of your suffering and stop it.
