Prevention
By Mayo Clinic staffThe best way to avoid an asthma attack is to make sure your asthma is well controlled in the first place. This means following a written asthma plan to track symptoms and adjust your medication.
While you may not be able to eliminate your risk of an asthma attack, you're less likely to have one if your current treatment keeps your asthma under control. Take your inhaled medications as prescribed in your written asthma plan. These preventive medications treat the airway inflammation that causes asthma signs and symptoms. Taken on a daily basis, these medications can reduce or eliminate asthma flare-ups — and your need to use a quick-relief inhaler.
See your doctor if you're following your asthma action plan but you still have frequent or bothersome symptoms or low peak flow readings. This is a sign that your asthma isn't well controlled, and you need to work with your doctor to change your treatment.
If your asthma symptoms flare up when you have a cold or the flu, take steps to avoid an asthma attack by watching your lung function and symptoms and adjusting your treatment as needed. Be sure to reduce exposure to your allergic triggers.
When exercising in cold weather, wear a face mask.
