In which scenario are daily controller medications typically unnecessary?

Daily controller medications are typically unnecessary in cases of intermittent asthma. This condition is characterized by symptoms that occur less than twice a week and nighttime symptoms that happen less than twice a month. Since the frequency and severity of symptoms are minimal, individuals with intermittent asthma generally do not require ongoing control medications to manage their symptoms effectively. Instead, short-acting bronchodilators are often sufficient for relieving symptoms as they arise.

In contrast, mild persistent asthma, moderate persistent asthma, and severe persistent asthma involve more frequent symptoms and episodes, necessitating the use of daily controller medications to maintain asthma control and prevent exacerbations.
