What is the main action to take after using a dry powder inhaler (DPI)?

Rinsing the mouth after using a dry powder inhaler (DPI) is important, particularly if the medication contains corticosteroids. The main reason for this action is to help reduce the risk of oral thrush, a fungal infection that can occur in the mouth and throat due to the deposition of medication. Rinsing can also minimize other potential side effects, such as hoarseness or irritation in the throat.

When using a DPI, it's crucial to ensure that the medication is properly inhaled to achieve the desired effect, and rinsing afterward is a beneficial practice for maintaining oral health and preventing complications. This action supports an effective asthma management plan and emphasizes the importance of understanding medication use in context.

While keeping the inhaler vertical, not exhaling, and using a spacer are considerations for different types of inhalers or in specific contexts, they do not address the immediate health concern after using a DPI, which centers around reducing medication-related side effects in the mouth.
