Before Pulmonary Function tests, how long should I be off Symbicort?

I went through pulmonary testing before lung surgery, I also use Symbicort however I wasn’t told to stop it before testing, maybe it just depends on the doctor who decides. How long do you have to stop before the tests?

@ckoehring Please ask your doctor or their staff. If this is a first or baseline test, they may want you to stop. My PFT's now are to track my progress or regression - I take it with all pulmonary and heart meds at full dosage.

I have it on Friday. So will definitely take it tonight. I didn't take it this morning, and I can feel the difference already with more wheezing and coughing.
Will check with doc. in am. Thanks!

No problem, it’s always better to check with the doctor to be safe, I hope you feel better soon, 🙂

This has been one of my biggest confusions over the course of the past years lung issues. My former Dr never mentioned stopping before PFTs (but he is my former Dr for several reasons). When I went to Mayo Clinic their instructions were no Symbicort 24 hours before the test. When I checked in with my new pulmonary team the nurse checked with the respiratory therapist who said no need to stop anything. When I pressed her to ask my Dr, the Dr responded that she wanted me to hold off for 12 hours unless I really needed it. So my recommendation is to ask your Dr and then ask why they would recommend that so you know in case you switch drs and they read your test without knowing if the inhaler was a factor.
