Abstract

The present invention relates to a dose counter. Particularly, but not exclusively, the invention relates to a dose counter for use with a Metered Dose Inhaler (MDI). The dose counter comprises a rotary counting element (26) and an actuator (2). The actuator (2) is movable relative to the rotary counting element (26) and comprises a shaped part (17) which can move into and out of engagement with a complementary feature (33) of the rotary counting element (26) when the actuator (2) moves between first and second positions. When the shaped part (17) of the actuator (2) is engaged with the complementary feature (33) of the rotary counter element (26), rotation of the rotary counter element (26) is resisted.
