The New Spiriva Test: Spiriva inhibits wheezing while the test is used to provoke it so, yes,the test will be affected.At that point maybe call it a "Spiriva Test" in that,if it resists the effects of the methacholine, then it would probably work for you! But,of course,that's not how the test is done.They'd want you off that med for a day or two before doing the test-and any other respiratory meds you take, if possible
