1. An inhaler for metered dose inhalation, the inhaler comprising:
a main body having a canister housing,
a medicament canister, which is moveable relative to the canister housing and retained in a central outlet port of the canister housing arranged to mate with a canister fire stem of the medicament canister, and
a dose counter having an actuation member having at least a portion thereof located in the canister housing for operation by movement of the medicament canister,
wherein the canister housing has an inner wall, and a first inner wall canister support formation extending inwardly from a main surface of the inner wall,
wherein the canister housing has a longitudinal axis X which passes through the center of the central outlet port, and
wherein the first inner wall canister support formation, the actuation member, and the central outlet port lie in a common plane coincident with the longitudinal axis X such that the first inner wall canister support formation protects against unwanted actuation of the dose counter by reducing rocking of the medicament canister relative to the main body of the inhaler.
