A dry powder inhaler for delivering medicament from at least one medicament carrier having a plurality of spaced-apart medicament doses, the dry powder inhaler comprising: a housing having regions for accommodating unused and used portions (13a, 13b) of the medicament carrier; a mouthpiece component joined to the housing and through which a user is able to inhale, the mouthpiece component including surfaces for contacting the user's lips; a dispensing mechanism arranged in the housing for moving a next medicament dose of the medicament carrier to a dispensing position; and a mouthpiece cover rotatably connected to the housing for sequential movement about a rotation axis from a first position in which the mouthpiece component is completely covered to a second position, and from the second position to a third position in which the mouthpiece component is completely uncovered, the second position being between the first and third positions, wherein the mouthpiece cover is coupled to the dispensing mechanism such that movement of the mouthpiece cover drives the dispensing mechanism, characterised in that the coupling is arranged such that movement of the mouthpiece cover from the first position to the second position does not cause the next medicament dose of the medicament carrier to move, and movement of the mouthpiece cover from the second position to the third position does cause the next medicament dose of the medicament carrier to be moved to the dispensing position, with the next medicament dose starting to move to the dispensing position when the mouthpiece cover moves through the second position, wherein movement from the first position to the second position encloses an angle about the rotation axis of at least 5 degrees, and the mouthpiece component is completely covered when the mouthpiece cover is in the second position. a housing having regions for accommodating unused and used portions (13a, 13b) of the medicament carrier; a mouthpiece component joined to the housing and through which a user is able to inhale, the mouthpiece component including surfaces for contacting the user's lips; a dispensing mechanism arranged in the housing for moving a next medicament dose of the medicament carrier to a dispensing position; and a mouthpiece cover rotatably connected to the housing for sequential movement about a rotation axis from a first position in which the mouthpiece component is completely covered to a second position, and from the second position to a third position in which the mouthpiece component is completely uncovered, the second position being between the first and third positions, wherein the mouthpiece cover is coupled to the dispensing mechanism such that movement of the mouthpiece cover drives the dispensing mechanism, characterised in that the coupling is arranged such that movement of the mouthpiece cover from the first position to the second position does not cause the next medicament dose of the medicament carrier to move, and movement of the mouthpiece cover from the second position to the third position does cause the next medicament dose of the medicament carrier to be moved to the dispensing position, with the next medicament dose starting to move to the dispensing position when the mouthpiece cover moves through the second position, wherein movement from the first position to the second position encloses an angle about the rotation axis of at least 5 degrees, and the mouthpiece component is completely covered when the mouthpiece cover is in the second position.
