ICS vs ICS/LABA: QVar is an inhaled cortisone (ICS)which helps to reduce airway inflammation. It is supposed to have a smaller particle size to reach the more distant airways in the lung. Dulera (formoterol and mometasone) is another ICS but combined with a long acting bronchodilator (LABA)- the latter has a black box warning about risk for asthma deaths. However the ICS/LABA more effective and the black box warning mostly disproved.
