Why is there a boxed warning on Dulera?

There is a boxed warning on the asthma drug Dulera (mometasone and formoterol) because one of the ingredients in it, formoterol, belongs to a class of drugs called long-acting beta-agonists, or LABAs. Research has shown that people with asthma who take LABA medications have an increased risk of death from asthma. In addition, children and teens who take LABA drugs have an increased risk of being hospitalized for asthma problems.

If your symptoms do not improve or if they worsen within one to two weeks of taking Dulera, call your doctor. If you experience a sudden worsening of your symptoms that isn't relieved by using a rescue inhaler, call 911.
