Test: Pulmonary Function and Methacholine Challenge Tests

Your doctor has requested that you have a breathing test. These tests are not painful and may take up to one hour. Some medications will interfere with the testing and should be withheld, if possible, prior to your test. However, if you do not think that you can go without, or you develop significant respiratory symptoms, then continue your usual routine and inform the therapist that you have taken your medications before starting your test.

IF POSSIBLE DO NOT TAKE:

Short-acting bronchodilators for at least 8 hours prior to the start of your test. These may include but are not limited to: Airomir, Atrovent, Bricanyl and Ventolin (Salbutamol).

Long-acting bronchodilators for at least 18 hours prior to the start of your test. These may include but are not limited to: Advair, Oxeze, Serevent, Symbicort and Zenhale.

Long acting anticholinergics such as Spiriva should be withheld for 24 hours.

CONTINUE TO TAKE:

All anti-inflammatory (steroid containing) medications. These may include but are not limited to: Alvesco, Flovent, Pulmicort, Prednisone and Qvar.

After the test you may restart all your medications in the usual manner. If you have any concerns regarding your medications or the test, please contact your doctor.
