What are leukotriene modifiers for the treatment of nasal allergies?

Donna Hill Howes, RN
Family Practitioner

Leukotriene modifiers block chemicals that cause inflammation and constriction of the airways. They can be used alone or in combination with other allergy medications. The leukotriene modifiers available in the US are montelukast (Singulair) and zafirlukast (Accolate). Only montelukast is FDA-approved for treating nasal allergies.
