These highlights do not include all the information needed to use Aridol safely and effectively. See full prescribing information for Aridol.
Warning: Risk Of Severe Bronchospasm
See full prescribing information for complete boxed warning.
Mannitol, the active ingredient in Aridol, acts as a bronchoconstrictor and may cause severe bronchospasm. Bronchial challenge testing with Aridol is for diagnostic purposes only. Only trained professionals under the supervision of a physician who are familiar with the management of acute bronchospasm should perform bronchial challenge testing with Aridol. Medications (such as short acting inhaled beta-agonist) and equipment to treat severe bronchospasm must be present in the testing area. Because of the potential for severe bronchoconstriction, bronchial challenge testing with Aridol should not be performed in any patient with clinically apparent asthma or very low baseline pulmonary function tests (e.g., FEV1<1-1.5 liters or <70% of the predicted values)
Aridol Indications and Usage
Mannitol, the active ingredient in Aridol, is a sugar alcohol indicated for the assessment of bronchial hyperresponsiveness in patients 6 years of age or older who do not have clinically apparent asthma.
Limitations of Use: Aridol is not a stand alone test or a screening test for asthma. Bronchial challenge testing with Aridol should be used only as part of a physician's overall assessment of asthma.
