How it works

Dulera (Mometasone / Formoterol) is a combination asthma medicine. Mometasone (a corticosteroid) lowers lung inflammation and works to control your asthma and prevent asthma attacks. Formoterol (a long-acting bronchodilator) relaxes muscles in your lungs to open airways and prevent wheezing and shortness of breath.
