What is Zyflo CR?
Generic Name: zileuton
Zileuton is a leukotriene (loo-koe-TRY-een) inhibitor. Leukotrienes are chemicals your body
releases when you breathe in an allergen (such as pollen). These chemicals cause swelling in your lungs
and tightening of the muscles around your airways, which can result in asthma symptoms.
Zileuton is used to prevent asthma attacks in adults and children as young as 12 years old.
Zileuton may also be used for other purposes not listed in this medication guide.
