Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Montelukast (Singulair) and Symbicort (budesonide/formoterol) are both used to manage asthma, but they work in different ways and have distinct uses. Montelukast is a leukotriene receptor antagonist taken orally, which helps reduce inflammation and swelling by blocking leukotrienes. It's also used for treating year-round and seasonal allergies and preventing exercise-induced asthma. Symbicort, on the other hand, is an inhaler that combines a corticosteroid (budesonide) and a long-acting beta-agonist (formoterol) to reduce lung inflammation and relax airway muscles. Symbicort is used for both asthma and chronic obstructive pulmonary disease (COPD). Montelukast is typically taken once daily, while Symbicort is used twice daily. Montelukast is available in generic form and is suitable for children as young as 1 year old, whereas Symbicort is available in two strengths and is safe for children 6 years and older for asthma. Montelukast can cause serious mental health side effects, while Symbicort may lead to oral thrush and bone loss with long-term use.

Summary of Singulair vs. Symbicort
Summary for Leukotriene receptor antagonist
Prescription only
Montelukast (Singulair) is an oral medication used for allergies. It's also used for the long-term treatment of asthma and prevention of exercise-induced asthma. This medication can't be used for a sudden asthma attack, since it takes a longer time to work compared to some inhalers. It's usually an add-on treatment for asthma that might be hard to control.
