What is a methacholine challenge?
This is a breathing test done to help your doctor see if you may have asthma. You
will be asked to breathe in a mist that contains methacholine. This mist may have
no effect on your breathing. You may cough or stay the same. You will be asked
to breathe increasing doses, with breathing tests done between each dose. The test
will take 30 to 90 minutes.






How do I prepare for this test?
ξ Do not exercise or eat a heavy meal for at least four hours before the test.
ξ Try to not have any caffeine, coffee, tea, cola drinks or chocolate.
ξ If you have or have had a recent cold, flu or other illness this test will need
to be scheduled two weeks following the end of your illness.

How will I feel after the test?
You should feel fine after your test. If you do have any shortness of breath or
