What action should a client take after using inhaled medication?

After using inhaled medication, the client should cough and spit up any residues as this action helps clear the airways of any remaining medication that may not have been fully inhaled or that can contribute to irritation. This is particularly important for inhalers that deliver corticosteroids, as residues left in the mouth or throat can lead to side effects, such as oral thrush or hoarseness.

Coughing can help dislodge any medication that may have stayed in the throat rather than entering the lungs, ensuring that the intended therapeutic effect is maximized while minimizing potential side effects. It is also a good practice to maintain oral hygiene after inhaler use, as some medications can cause irritation or an increased risk of infection.

Drinking water immediately can be helpful in preventing dry mouth but does not directly relate to the efficacy of the medication. Waiting for further instructions isn't necessary, as clients typically have a clear understanding of the steps to take after using their inhalers. Taking additional puffs without proper guidance can lead to overmedication or increased side effects.
