Your asthma action plan

2) How to use your asthma action plan

Your nurse will talk through your asthma action plan with you when they write it out.

  • The plan will have 3 or 4 “zones” usually in the form of traffic lights -green, yellow/amber and red.
  • Each zone tells you what action to take if you have mild symptoms, worsening symptoms or an emergency.

Personalised asthma action plans have been shown to help people with asthma manage their asthma safely.

You must follow your action plan and take the action as advised.

The plan is designed to keep your asthma under control and make sure you are seen at an early stage by a doctor or nurse before things get too bad.


Don’t stay at home if your plan tells you to get a medical review.
