An indicating device for indicating the number of dosages of medicament dispensed from a container includes a housing, a single indicator member nested the housing, an actuator and a drive mechanism. The drive mechanism is periodically engageable with the single indicator member. The drive mechanism is operable to advance the single indicator member an incremental amount when the drive mechanism is engaged with the single indicator member. The single indicator member remains stationary and is free of engagement from the drive mechanism for at least some reciprocal movements of the actuator. A dispensing device and a dispensing system are also provided.
