Apparatus, having an outlet port insertable within a user's mouth, has housed therein an automatically actuated commercially available and replaceable inhaler for discharging a medicated vapor through the outlet port into the user's mouth upon inhalation. A pivotable spring loaded plate within the apparatus bears upon the inhaler to actuate the inhaler upon operation of a trigger mechanism. The trigger mechanism includes a valve operable in response to a slight vacuum developed within the apparatus upon inhalation by a user. Operation of the valve anularly displaces a sear to release a cam associated with a pivot mechanism of the spring loaded plate. The released cam permits rotation of the spring loaded plate to effect discharge from the inhaler into the user's mouth. A manually operated rocker arm recocks the spring loaded plate and rotates the cam into engagement with the sear to retain the spring loaded plate in the cocked state.
