Asthma: when to call your doctor

Watch out for these warning signs that may mean you’re losing control of your asthma:

  • Your reliever doesn’t open up your tight chest within a few minutes.
  • You use reliever medication more than twice a week (unless it’s for exercise).
  • You’re using more puffs of your reliever than usual.
  • You’re more breathless than usual.
  • You’re waking up at night as a result of asthma symptoms (this is an important feature of worsening asthma).
  • You experience a tight chest some mornings.
  • You’re coughing persistently and/or you notice a change in the colour of the mucus.
  • Your peak-flow readings show a downward trend (i.e. they worsen over a couple of days).

Talk to your doctor as soon as possible if you experience any of the above. Call emergency services immediately if you're having an asthma attack.

If your asthma remains poorly controlled despite intensive treatment and correct usage, your doctor should refer you to a specialist physician or pulmonologist.
