It could: It could potentially cause a false negative methacholine test. Even asthma patients taking no medications for a while could potentially have a negative methacholine test for various reasons. That's why it is best to diagnose asthma based on symptoms and not a methacholine test.

Will a combination of Dulera (formoterol and mometasone) and Singulair produce a false negative result on a Methacholine challenge?

Yes: You will need to stop these medications prior to your testing. Usually dulera (formoterol and mometasone) needs to be discontinued about 2 weeks prior and singular 24 hours prior. Check with your doctor who ordered the test and ask when to stop these medications.

Will Dulera (formoterol and mometasone) significantly affect a methacholine challenge?

Yes: Should meds be stopped before a methacholine challenge? Yes. A methacholine challenge is used to diagnose asthma. Dulera (formoterol and mometasone) is a combination medication with a long-acting beta agonist and a steroid. Long-acting beta agonists should be stopped prior to testing for accurate results. Speak with your doctor to find out exactly how long you need to be off prior to testing (usually 2 days).
