Asthma is a variable disease. This means your symptoms can vary over time. Things like respiratory infections, allergies, pollution, or stress can make your asthma temporarily worse at certain times of the year. While these fluctuations are to be expected, you can take control of your symptoms by having a good asthma action plan.

Except in the mildest cases of asthma, reliever medications on their own will not control your asthma over time, so if you've been prescribed a controller medication, don't skip using it. Use all your medications as prescribed. Don't stop using your asthma medications without consulting with your doctor.

The plan will give you the knowledge you need to keep your asthma under control and take action if your symptoms get worse. This way, you'll be better able to handle the variable symptoms of this condition.
