The auto-injector comprises a housing (20) arranged for receipt of a syringe containing a liquid drug formulation,- an actuating mechanism for actuating said syringe (10) to deliver said liquid formulation to a patient; and a visual indicator comprising a colour change material (62) that defines a first colour state below a transition temperature and a second colour state above said transition temperature. The visual indicator is arranged to allow the user to differentiate between a 'too cold to use' state (i.e. below the transition temperature) and a 'sufficiently warm to use' state.</p> |
