What are Singulair® Tablets?

Singulair® Tablets is a prescription medication used for the long-term control and prevention of asthma symptoms. It contains montelukast, which belongs to a class of medicines called leukotriene receptor antagonists (LTRAs). It may also be used for certain allergy symptoms, but for asthma, it is taken regularly to help reduce ongoing airway inflammation—not for sudden breathing problems.

  • Belongs to a class called leukotriene receptor antagonists (LTRAs)
  • Taken as an oral tablet (commonly 5 mg or 10 mg strengths)
  • Not a rescue medication for asthma attacks

  • Do not use extra doses for sudden symptoms


Always follow your provider’s instructions and keep a rescue inhaler available if one has been prescribed.
