Hannah is a 4 year old girl who attends with her father for a review. She is currently using an inhaled corticosteroid (ICS) and Montelukast for the last 3 months for suspected Asthma. She is experiencing cough and wheeze symptoms again and she is using her Salbutamol inhaler at least three times a week. She is not currently suffering from an exacerbation but has had 2 in the last 3 months.
