Asthma exacerbation treatment: what to expect

A reliever inhaler is commonly used first, following the personal asthma action plan. More severe episodes may require oxygen, repeated inhaled medicine, corticosteroids, monitoring, or hospital care. The exact approach depends on breathing effort, response to medicine, and oxygen levels.

During an exacerbation, muscles around the airways tighten while the airway lining becomes swollen and may produce more mucus. Asthma commonly presents with wheezing, cough, chest tightness, or shortness of breath; symptoms can build gradually or worsen abruptly.

Triggers may include a respiratory infection, smoke, dust, allergens, exercise, weather changes, or missed controller medicine. Identifying the likely trigger helps with prevention, but urgent treatment should not wait while you search for a cause.

Sit upright, stay as calm as possible, move away from smoke or another obvious trigger, and use your prescribed reliever exactly as directed in your action plan. A spacer can improve delivery when it has been prescribed with a metered-dose inhaler.

If symptoms do not settle as your plan says they should, obtain urgent medical assessment. After recovery, arrange a review of inhaler technique, controller treatment, triggers, and the action plan; needing repeated reliever doses can signal poor control.

Call emergency services now if breathing is very difficult, speech is limited to a few words, the lips or face look blue or grey, there is marked drowsiness or confusion, the chest seems unusually quiet, or the prescribed reliever is not helping. Do not drive yourself when severely breathless.

Seek prompt same-day care for steadily worsening wheeze, nighttime waking, reduced ability to do usual activities, or relief that wears off sooner than expected.

Ask which medicine is the reliever, how to use any spacer, when oral corticosteroids are appropriate, and what change should trigger urgent care. Request a written action plan that clearly separates everyday treatment from flare-up instructions.
