Which MDI inhaler does not require shaking before use?

  1. Alvesco

  2. QVAR RediHaler

  3. Ventolin

  4. Proventil

The correct answer is: QVAR RediHaler

The QVAR RediHaler does not require shaking before use because it is a breath-actuated inhaler, which means that the medication is released automatically when you inhale. This type of inhaler eliminates the need for shaking before use, as seen with conventional pressurized metered-dose inhalers to ensure proper mixing of the medication before administration. In contrast, the other options (Alvesco, Ventolin, and Proventil) are traditional MDI inhalers that require shaking before use to ensure the proper distribution of the medication within the device.
