A nebulizer includes a nebulizer body having an air channel section, medication reservoir and nebulizer outlet. An air line has an inlet at one end and extends through the air channel section and has a venturi nozzle oriented horizontally when in use and an outlet and configured to form a low pressure mixing chamber. The air line provides a pulsed flow of gas between the inlet and outlet end. The venturi nozzle and medication reservoir are received within an oral cavity of a patient when in use. A primary suction line extends from the medication reservoir to the low pressure mixing chamber through which medication is drawn upward and mixed with gas passing through the venturi nozzle and nebulized for pulsed discharge through the nebulizer outlet during nebulization.
