If for some reason you cannot be present for testing, please notify us 24 hours ahead. Methacholine has a very short shelf life and has to be discarded if not used. It is prepared on the testing day by our staff. If you do not cancel and miss your test, you may be billed for the cost of the medication.
If you have an asthma reaction from the methacholine, we will reverse this with asthma medication. The discomfort from the asthma attack will only be for a brief time.
