A medication inhaler includes an elongated hollow body for improved misting of the medication. A sonic signalling device is provided which is exposed to the inside of the inhaler and to outside air. The sonic signalling device comprises an integrally molded plastic body and vibratory reed. If a person inhales too rapidly, the reed will be set in vibration by reduced pressure inside the inhaler, whereby to generate a pleasant musical tone to alert the user that he is inhaling too rapidly. |
