Prevention and Treatment
Therapy for asthma consists of medications designed to prevent an asthma attack as well as medications used to relieve symptoms once an attack has occurred. A person with asthma must be very careful to take the correct medication at the appropriate time and not mix them up -- for example, both prevention and relief medications for asthma may be supplied in inhalers. This is very important since some medications are useful only for attack prevention and do not work once an attack has occurred.
