The present invention relates to a syringe for delivering only a single dose of a medicament at each actuation of the syringe. The device of the invention comprises a cylinder adapted to contain the medicament and having a piston journalled in the bore of the cylinder for axial movement in the bore towards an outlet provided with a needle or adapted to receive a needle in mounting engagement therewith, the piston being adapted to be moved axially within the bore of the cylinder by means of a plunger member, which plunger member carries one or more drive teeth adapted to engage with teeth carried by an axially movable drive member adapted to be acted upon by the user, characterised in that: a) the axial spacing between axially adjacent teeth on one of the plunger member or the drive member corresponds to the forward axial movement of the plunger member required to discharge a single dose of medicament; and b) means are provided for retracting the drive member axially a predetermined distance corresponding to one said tooth spacing with respect to the plunger whereby forward axial movement of the drive member with the teeth of the drive and plunger members engaged is adapted to administer said single dosage of the medicament.
