An inhaler includes a first body member and a second body member fit closely together to form an inhaler body, and an outlet. The first body member has a medicament chamber containing a unit dose of powdered medicament. A seal such as a foil strip seals the medicament chamber and extends outwardly of the inhaler body. In use, one end of the seal can be grasped by a user and withdrawn, fully or partially, from the inhaler body, to release the powdered medicament from the medicament chamber. The second body member includes a medicament collection well in which the medicament is collected upon its release from the medicament chamber. The medicament collection well forms part of an airway connecting into the outlet. In use, air can be drawn by inhalation at the outlet to entrain the powder medicament in the collection well for inhalation by a user.
