Treating asthma in children under 5

Quick-relief rescue medicines

These medicines can relieve asthma symptoms right away, and the effects last 4 to 6 hours. Quick-relief medicines for asthma include albuterol (ProAir HFA, Ventolin HFA, others) and levalbuterol (Xopenex HFA).

For children with mild, occasional asthma symptoms, this type of medicine may be the only treatment that is needed.

For young children who have ongoing asthma and use long-term control medicines, quick-relief medicine is used to treat asthma attacks. It also may be used to prevent asthma symptoms triggered by exercise.

Overuse of quick-relief medicines usually means that a healthcare professional needs to change the long-term control treatment plan.
