Abstract: A medicine dispensing pacifier has a centered nipple upon a guard and a reservoir communicating through the guard to the nipple. The reservoir, opposite the guard, has a cap, and upon removing it, a caregiver places medicine into the reservoir. Then the caregiver returns the cap to seal the reservoir. The infant then suckles the nipple, ingesting the medicine drawn from the reservoir. Alternately, the pacifier includes an air permeable membrane, a flexible cap, for dispensing medicine under pressure through a nipple into an infant that has difficulty taking medicine. The infant then suckles upon the nipple and the caregiver presses upon the cap raising the flow of medicine through the nipple into the mouth of the infant. The cap augments the natural suckling of the infant with pressure and without spilling medicine.
