An improved nebulizer places a venturi in close proximity to or inside a patient's oral cavity. One or more medicine feed lines feeds the medicine to a location proximate to a venturi. One or more air curtain conduits may be positioned near the medicine feed line and the venturi and is fed by a source of air pressure to create a curtain of fluid flow to surround at least in part the flow path of the nebulized medication. This minimizes the amount of medication lost to the oral cavity and to the trachea and permits more medication to reach a patient's lungs. Medication contained in a patients exhalant can be filtered in an exhale conduit to prevent loss to the environment and can be recaptured for reuse.
