What should be done if an inhaler has not been used in 3 days?

When an inhaler has not been used in 3 days, it is important to prime it before use to ensure that the medication is delivered effectively. Priming involves releasing a few doses of the inhaler into the air to ensure that the medication flows properly. This process helps in clearing any potential blockages in the device and ensures that the patient receives the correct dose of medication upon their first use after a period of inactivity.

This is particularly crucial for metered-dose inhalers (MDIs) and some other types of inhalers, as they may require priming if they have not been in use for a certain period. The priming action helps to maintain the proper functioning of the inhaler, ensuring accurate dosing and effective treatment upon re-initiation of therapy.

Other options such as discarding the inhaler, cleaning it thoroughly, or storing it in the refrigerator are not appropriate actions for an inhaler that has simply been unused for a few days. Discarding it may lead to unnecessary waste of medication, while refrigeration is not recommended as it can affect the medication's stability and effectiveness. Cleaning the inhaler is important in general maintenance but is not necessarily indicated in this specific scenario of non-use for 3 days.
