What if I use inhalers, nebulizers, or oral asthma medications?
| Some medications can interfere with the breathing tests. If possible, do not take these medications before your medical testing, as described below. However, if you need to use your medication, please do so and still have the medical testing. If you have any questions, please contact your healthcare provider. You may also contact the NIOSH physician at 1-800-232-2114.
