A fluid dispensing device for dispensing a fluid form medicament formulation having a viscosity of from 10 to 2000 mPa·s. is disclosed and comprises a housing and a fluid discharge device. The fluid discharge device is arranged to be actuated by one or more levers so as to apply a force to the fluid discharge device which is used to move a container forming part of the fluid discharge device along a longitudinal axis of the fluid discharge device to cause actuation of a pump forming part of the fluid discharge device. A pre-load means is used to prevent actuation of the pump until a pre-determined force is applied to each lever of sufficient magnitude to guarantee the production of a well developed efficient spray from the fluid dispensing device.
