A Note about Long-Term Controller Medicines in Children
According to the National Asthma Education and Prevention Program at the National Institutes of Health, long-term controller medicines should be considered when infants or young children have had three or more episodes of wheezing in the previous 12 months and who are at an increased risk of developing asthma because of their own or their parents' history of allergic diseases.
They also recommend long-term controller medicines for children who need short-acting bronchodilators (rescue medicines) more than twice a week or have had severe asthma symptoms less than six weeks apart. Without a controller medicine, the underlying inflammation will continue to cause more asthma symptoms.
