What treatment is preferred for patients experiencing asthma symptoms less than 3-5 days a week?

The preferred treatment for patients experiencing asthma symptoms less than 3-5 days a week is, indeed, the use of a rescue inhaler containing a low-dose inhaled corticosteroid (ICS) combined with formoterol, like Symbicort. This approach is rooted in the understanding that such infrequent symptoms suggest a lower severity of asthma, allowing for effective control without the need for daily medications.

Using a PRN (as needed) low-dose ICS-formoterol allows patients to manage their symptoms effectively while also addressing underlying inflammation with the inhaled corticosteroid component. This method has been shown to provide both rescue and preventative benefits by allowing users to gain rapid relief from acute symptoms while reducing the frequency of exacerbations over time.

This treatment strategy is particularly beneficial as it minimizes the risk of overtreatment and unnecessary side effects that can come from daily high-dose inhaled corticosteroids, regular use of oral steroids, or frequent nebulizer treatments. Each of those alternatives may be appropriate for more severe manifestations of asthma but is not suitable for patients with infrequent symptoms. Rather, the PRN option encourages patient autonomy and a better quality of life while maintaining adequate asthma control.
