Asthma experts define well-controlled asthma by the following criteria:
• Your asthma symptoms require a rescue inhaler (quick-reliever medication like albuterol) no more than 2 days/week
• Your asthma doesn't wake you up more than 2 nights/month
• Your lung function (as measured by peak expiratory flow or spirometry) is normal or within 20% of your best PEF or FEV1)
• In the past 12 months, you haven't had more than one asthma exacerbation where you needed oral glucocorticoids and/or urgent medical care
• You're able to do all your normal activities
If you don't meet these criteria or you've needed to take oral steroids or receive urgent medical care for your asthma within the past 4 weeks, you'll need to see a primary care provider for an in-person evaluation. You may need a new medication or a different dose of medication to control your asthma symptoms.
