An indicating device includes an indicator housing member having a first circumferential wall defining an interior surface and a substantially circumferential cavity having a longitudinal axis. An engagement member is formed on the interior surface and a viewing window is formed through the first wall. An indicator member has a second circumferential wall with an exterior surface having dosage indicia and a bottom rim. The indicator member is rotatably mounted within the indicator housing member about the longitudinal axis and interiorly of the substantially circumferential cavity with at least a portion of the dosage indicia being progressively visible through the viewing window as the indicator member is rotated about the longitudinal axis relative to the indicator housing. The bottom rim of the indicator member is supported by the engagement member. One of the indicator member or indicator housing has a plurality of indentations, while the other of the indicator member or indicator housing has at least one indexing member, with the indexing member being selectively engaged with at least one of the plurality of indentations.
