An accessory (50,80) adapted to be used with a breath actuated inhaler (10), the breath actuated inhaler (10) comprising an air inlet (19), an outlet (20) for delivering medicament and a trigger mechanism (30) for triggering the delivery of a dose of the medicament in response to a flow (40) between the air inlet (19) and the outlet (20), wherein the accessory comprises: a pressure assist unit (52, 54) for application to the air inlet, comprising an assist chamber (52) for holding a volume of air and a mechanical release system (54, 70) for expelling air from the assist chamber to the air inlet, at a rate sufficient to trigger the trigger mechanism. Hence, it has an assist chamber for holding a volume of air and a mechanical release system for expelling air from the assist chamber to the air inlet, at a rate sufficient to trigger a dose trigger mechanism of the breath actuated inhaler. In this way, a user may use a breath actuated inhaler even if they do not have the ability to generate an inhalation suitable for activating the inhaler.
