A nebulizer comprising a nebulizing chamber with a vibrating mesh grid having a plurality of precision openings and said chamber with a liquid pharmaceutical product in a cartridge contacting the mesh grid for producing particle sizes of two (2) to four (4) microns; and an entrainment port for drawing air into the nebulizing chamber and through the grid. A control circuit, a source of electrical energy in said circuit such as two 1.5 volt lithium titanate batteries connected to said grid for producing vibration. A switch to turn said grid off and on and means for providing a first measured time period of four seconds for taking a first breath of air through the entrainment port and grid and through the thousands of passageways into the lungs and bloodstream of an individual. A second time period during which no vibration occurs. The grid is also self-cleaning as described.
