A device for delivering a beneficial agent within a body cavity such as the ear canal. The device preferably includes a soft resilient casing that can be compressed to fit at least partially within the ear canal. Once inserted in the ear canal, the casing expands to form a seal between a boundary defining the ear canal and the device. The soft casing preferably encapsulates the beneficial agent within a reservoir formed inside the soft casing. As the device is squeezed, the beneficial agent is ejected through a release point. The device then maintains the beneficial agent within the ear canal until the beneficial agent has had time to take effect.
