It has an ihaled corticosteroird (ICS) and a long acting beta2 agonist (LABA - long acting broncho dilater).
It is not recommended that you stop taking the ICS all at once.
It is a steroid, although it doesn't have the same side effects of oral steroids. The ICS is really the primary treatment for asthma.
After you are feeling better, you can discus trying an ICS only medication like Asmanex or Alvesco with your doctor.
