An asthma action plan is a personalised, written document that explains how to manage your asthma day to day and what to do if your symptoms get worse. It is created together with your doctor or asthma nurse and acts as a set of instructions tailored specifically to your triggers and medications. This guide explains the importance of having a plan, how to use it, and how it can significantly reduce your risk of a serious asthma attack. You will learn about the different sections of the plan and how it helps you communicate your needs to others in an emergency.

What is the purpose of an asthma action plan?
An asthma action plan is a practical tool that helps you stay in control of your breathing by providing clear, step by step instructions. It is usually a single page divided into three main zones: green for when you are well, amber for when symptoms start to appear, and red for when you are having an asthma attack. By following the specific medicine doses and advice in each zone, you can respond quickly to changes in your health.
Research indicates that people who use a written action plan are significantly less likely to be admitted to the hospital for their asthma. This is because the plan removes the guesswork during a stressful situation, allowing you or a carer to take the right action at the right time. According to the latest UK clinical standards, a personalised plan is one of the most effective ways to reduce the risk of a life-threatening event.
- Clinical context: A plan is not a static document; it should be reviewed at least once a year or whenever your medication changes.
- Safety note: Your plan should always include the name and dose of your preventer inhaler and your reliever inhaler.
Do I need an asthma action plan?
Yes, every adult and child diagnosed with asthma should have a written action plan. It is a core part of the standard of care provided by the NHS. Even if your asthma is mild or you have not had an attack in a long time, having a plan is essential because asthma symptoms can flare up unexpectedly due to illness, weather changes, or new triggers.
A plan is particularly vital for children, as it can be shared with schools and nurseries to ensure staff know exactly how to help during a flare up. For adults, sharing the plan with family or colleagues can provide peace of mind and ensure that those around you are equipped to assist you if you become too breathless to speak.
- Key benefits:
- Recognition: Helps you spot early warning signs before they become serious.
- Consistency: Ensures you are taking the correct dose of medicine as prescribed.
- Emergency Preparedness: Provides a clear guide for others to follow if you need help.
How to use the green, amber, and red zones
The green zone is your ‘business as usual’ section. It describes what your breathing is like when your asthma is well controlled and lists the daily medications you must take to keep it that way. This usually includes your preventer inhaler, which builds up protection in your lungs over time.
The amber zone is for when your symptoms start to increase. You might notice you are coughing more at night, feeling wheezy, or needing your reliever inhaler more than three times a week. Your plan will tell you exactly how much extra medicine to take and when to contact your GP or asthma nurse for a review.
The red zone is the emergency section. This part of the plan is used when you are having a severe asthma attack. It provides clear instructions on how many puffs of your reliever inhaler to take and at what point you must call 999. It serves as a vital lifesaver by providing a clear protocol when you may be feeling panicked or struggling to breathe.
Triggers and personalised instructions
A high-quality asthma action plan will also list your specific triggers. These are the things that make your asthma worse, such as pollen, pet dander, cigarette smoke, or cold air. By documenting these, the plan helps you and your medical team identify patterns in your symptoms and adjust your environment or medication accordingly.
Personalised instructions may also include peak flow readings. A peak flow meter measures how fast you can blow air out of your lungs. Your plan will list your ‘best’ peak flow and tell you what to do if your readings drop to a certain percentage of that best score. This objective measurement can be a more reliable way to monitor your lung health than just how you feel.
Differentiating between a plan and a prescription
It is important to understand that an asthma action plan is not the same as a prescription. While a prescription tells the pharmacist which medicines to give you, the action plan tells you how to use those medicines in different scenarios. Think of the prescription as the ‘tools’ and the action plan as the ‘manual’ for using them.
| Feature | Prescription | Asthma Action Plan |
| Purpose | To obtain medication | To manage symptoms day to day |
| Content | Drug names and quantities | Step by step health instructions |
| Usage | Used at the pharmacy | Used at home, work, or school |
| Updates | When medicine runs out | At least once a year in a review |
Conclusion
An asthma action plan is an essential document for anyone living with asthma in the UK. It provides a clear, personalised roadmap for staying well, managing worsening symptoms, and responding to emergencies. By using the green, amber, and red zones, you can take proactive steps to protect your lung health and reduce the risk of hospitalisation. If you do not have a plan, speak to your GP or asthma nurse at your next review to create one together.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Where can I get an asthma action plan?
You can download a template from UK respiratory charities or ask your GP or asthma nurse to provide one during your next appointment.
Does a child need a different plan?
Yes, there are specific paediatric asthma action plans designed for children that include information for teachers and school staff.
How often should I update my plan?
You should update your plan at least once a year during your annual asthma review or whenever your doctor changes your medication.
Should I keep my plan on my phone?
It is a great idea to take a photo of your plan or keep a digital copy on your phone so you always have it with you but keep a physical copy at home too.
What if my triggers change?
If you discover new triggers, you should discuss these with your medical professional so they can be added to your amber zone instructions.
Do I still need a plan if I only have ‘mild’ asthma?
Yes, because even mild asthma can flare up into a serious attack, and having a plan ensures you know exactly what to do if that happens.
Can a school refuse to follow the plan?
In the UK, schools have a duty of care to support pupils with medical conditions, and following an asthma action plan is a standard part of that support.
