WELL-CONTROLLED ASTHMA MEANS YOUR SYMPTOMS ARE
LESS FREQUENT, YOU CAN DO ALL YOUR USUAL ACTIVITIES AND THE RISK OF FUTURE FLARE-UPS IS LOW1,2

Asthma control is the extent to which the features of asthma have been reduced or removed by treatment. It is based on:2,3

Symptom control

How often you experience symptoms, wake up at night and struggle to do usual activities

Risk of future adverse
outcomes

Asthma flare-ups (in particular), decline in how well your lungs work and side effects from treatment

Your asthma is well controlled when you experience very few symptoms throughout the day and night, can do all your usual activities and the risk of future flare-ups is low.1,2
