A counter for a handheld device for dispensing a pharmaceutical substance, has a housing, at least one counter wheel which has readable characters, and a drive part which is designed to rotate the counter wheel, the counter wheel being rotatably attached to a mounting part. The mounting part of the counter is designed independently of the housing, and the drive part is directly attached to the mounting part. The counter can have at least one counter wheel which has readable characters and a drive part which is designed to rotate the counter wheel. The counter wheel has readable characters and is designed in a cylindrical manner and with a central axis, and has a drive part which is designed to rotate the counter wheel, the counter wheel being provided with an engagement toothing via which the drive part acts on the counter wheel so as to rotate same, the drive part having a rotational axis.

This invention generally relates to counters and in particular to counters for use with dispensers and to dispensers comprising said counters. More particularly the present invention relates to counters for use with metered-dose dispensers, such as metered-dose inhalers (MDIs). In particular, the present invention provides a counter comprising: a first ring member having a first indicia and being rotatable in increments about an axis, the first indicia indicating a count; a limiting member comprising a limiting mechanism, wherein the limiting mechanism comprises an engaging portion arranged to act radially with respect to the first ring member to contact the first ring member to limit free rotation of the first ring member relative to the limiting member about the axis.
