A user activated iontophoretic device of the present invention includes an electrode assembly, an electrode reservoir and at least one drug reservoir. The device is divided or otherwise separated into at least two portions, with one portion containing the electrode reservoir and the other containing the drug reservoir, which may include a medication in a dry form. The electrode reservoir and the drug reservoir are sealingly separated by a barrier, which can be removed to bring the reservoirs into fluid conducting contact with one another. A method of activating the device includes causing the two portions to come into fluid conducting contact with one another to at least partially hydrate one of the reservoirs. This can be accomplished by removing the barrier dividing the two portions. In this way, the device is suitable for use to deliver a drug which has limited stability in an aqueous solution.

[ What is claimed is:] [1.] A user activated iontophoretic device for use in delivering at least one medication through an applied area of a patient, such as the skin, mucus membrane and the like, comprising:a first portion and a second portion, said first portion including an electrode assembly and a electrode reservoir and said second portion including a drug reservoir;said electrode assembly including electrode means for driving a medication into the patient to be absorbed by the body of the patient; andsaid drug reservoir containing an active compound to be delivered to the applied area of the patient, with the active compound being maintained in a dry state prior to activation of the device;barrier means for sealingly maintaining said first portion and said second portion separate from one another, with the electrode assembly maintained in electrically communicating relation with the electrode reservoir, and with the active compound contained by the drug reservoir maintained separate in relation to the first portion prior to activation so that upon removal of said barrier means, the electrode reservoir and the drug reservoir are brought into fluid conducting contact with one another so that said drug is dissolved in an aqueous solution contained in said electrode reservoir.
