In general, doctors start with a high level of therapy following an asthma attack and then decrease treatment to the lowest possible level that still prevents asthma attacks and allows your child to have a normal life. Every child needs to follow a customized asthma management plan to control asthma symptoms. The severity of a child's asthma can both worsen and improve over time, so the type (category) of your child's asthma can change, which means different treatment can be required over time. Treatment should be reviewed every one to six months, and the choices for long- and short-term therapy are based on how severe the asthma is.
