A member asked:
I just started using advair a week ago will this affect my methacholine test tomorrow? will this make false negatives?

Potentially: For a methacholine test to yield accurate results you should not take any medications that would mask the response. The most common reason for canceling this test is ablack of adequate patient preparation. Recommended periods for withholding medications are based on their duration of action. Call your testing center and address your concerns before going in. You may need to reschedule.
