A nebulizer device for use in administering liquid medication and fluids to the nasal passages utilizing the venturi and siphon effects to produce a mist in two air streams from one external air source. The nebulizer device comprises two major sections, a cap section and a reservoir section, with the cap section having an integrally molded pair of siphon tubes which fit over opposing pairs of air tubes attached to the reservoir section. Pressurized air introduced into the reservoir section travels through the air tubes and exits small diameter orifices which are position relative to similar small diameter orifices of the siphon tubes. This interface creates a venturi effect whereby liquid medication is siphoned from the bottom of the reservoir section, through the space provided between the inside diameter of the siphon tubes and the outside diameter of the air tubes, and exits as mist or liquid droplets through the small orifices of the siphon tubes. These two mist streams are directed to the two nostrils of the patient, while a nose shield attached to the cap section keeps the liquid medication out of the patient's eyes.
