Various embodiments of a breath-activated nebulizer with fluidic control and related methods of using such a nebulizer are disclosed. The nebulizer (10) may include a body (20) comprising a reservoir (22) for holding medication (30), a nozzle (74) for emitting a jet of pressurized gas, and a fluid conduit (26) in communication with the reservoir for delivery of the medication proximate the jet to produce an aerosol of medication. The nebulizer may also include a nebulizer outlet (29) in communication with an interior of the body for delivery of the aerosol to a patient, a control conduit (77) in fluid communication with the fluid conduit for delivery of a control gas to the fluid conduit to prevent the delivery of the medication proximate the jet, and a fluidic amplifier (54) configured to control the delivery of the control gas to the control conduit.
