Leukotriene (say "loo-koh-TRY-een") modifiers are drugs used for asthma and hay fever.
They treat asthma symptoms in adults. And in children, they improve how well the lungs work. They are not used to treat asthma attacks.
They also reduce symptoms of hay fever. These include sneezing and a runny or stuffy nose.
You may have other side effects or reactions. Check the information that comes with your medicine.
