What action should a patient take after using a dry powder inhaler?

After using a dry powder inhaler, it's important for the patient to swish and spit out the medication. This action helps to clear any residual medication from the mouth and throat, reducing the likelihood of systemic absorption and potential side effects. Additionally, swishing and spitting may help prevent oral thrush, a fungal infection that can occur if medications are left in the oral cavity, especially with steroid-based inhalers.

While rinsing and swallowing the medication could theoretically allow for additional medication absorption, it's not advised for dry powder inhalers, as these medications are typically designed for localized action in the lungs. Drinking water immediately or waiting before eating are not specifically recommended actions directly related to the use of a dry powder inhaler, making swishing and spitting the most appropriate response to manage the medication effectively after use.
