Singulair vs. Symbicort

Are Singulair and Symbicort the Same Thing?

Singulair (montelukast) and Symbicort (budesonide and formoterol fumarate dihydrate) are used to treat asthma.

Singulair is also used to treat allergic rhinitis and for prevention of exercise-induced narrowing of the airways.

Symbicort is also used to prevent bronchospasm in people with chronic obstructive pulmonary disease (COPD).

Singulair and Symbicort belong to different drug classes. Singulair is a leukotriene receptor antagonist and Symbicort is a combination of a steroid and a long-acting bronchodilator.

Side effects of Singulair and Symbicort that are similar include headache, stomach pain or upset, nausea, diarrhea, stuffy nose, and sore throat.

What Is Singulair?

Singulair (montelukast) is a leukotriene receptor antagonist drug used in the treatment of asthma and allergic rhinitis. Singulair is also indicated for prevention of exercise-induced narrowing of the airways.

What Is Symbicort?

Symbicort (budesonide and formoterol fumarate dihydrate) is a combination of a steroid and a long-acting bronchodilator used to prevent bronchospasm in people with asthma or chronic obstructive pulmonary disease (COPD).

Symbicort combines an inhaled corticosteroid medicine, budesonide and a LABA medicine, formoterol.

  • Inhaled corticosteroids help to decrease inflammation in the lungs. Inflammation in the lungs can lead to breathing problems.
  • LABA medicines are used in people with chronic obstructive pulmonary disease (COPD) and asthma. LABA medicines help the muscles around the airways in your lungs stay relaxed to prevent symptoms such as wheezing, cough, chest tightness, and shortness of breath. These symptoms can happen when the muscles around the airways tighten. This makes it hard to breathe. In severe cases, wheezing can stop your breathing and may lead to death if not treated right away.
