578 AeroBid® (flunisolide) Effective asthma control BID For oral inhalation only CONTRAINDICATIONS AeroBid Inhaler is contraindicated in the primarytreatment of status asthmaticus or other acute episodes of asthma where intensive measures are required. Hypersensitivity to any ofthe ingredients of this preparation contraindicates its use. WARNINGS Particularcare is needed in patientswhoare transferred from systemicallyactivecorticosteroids to AeroBid Inhaler be- causedeaths duetoadrenal insufficiency have occurred in asthmatic patients duringand aftertransfer from systemic corticosteroidsto aerosol corticosteroids. Afterwithdrawal from systemic corticosteroids, a number of monthsare re- quiredfor recoveryof hypothalamic-pituitary-adrenal (HPA) function. During this period of HPAsuppression, patients mayexhibit signsand symptomsofadrenal insufficiencywhen exposed to trauma, surgery or infections, particularly gastroenteritis. Although AeroBid Inhalermayprovidecontrol ofasthmatic symptomsduring theseepisodes, it does NOTprovidethesystemic steroidthat isnecessary for coping with theseemergencies. During periods ofstress orasevereasthmaticattack, patientswwho have been withdrawn from systemiccorticosteroids should be instructed to resumesystemic steroids (in large doses) immediatelyand to contact their physician forfurther instruction. These patients shouldalso be instructed tocarryawarning card indicating that they may need supplemen- tarysystemic steroids during periods of stressorsevere asthma attack.Toassessthe risk ofadrenal insufficiency in emergencysituations, routine tests ofadrenal cortical function, including measurement ofearly morning resting cortisol levels, should beperformed periodically in all patients. An earlymorning resting cortisol level may beaccepted as nor- mal if itfallsatornearthenormal mean level. Localized infections with Candidaalbicans orAspergillus niger have occurred in the mouth and pharynxand occasionally in the larynx. Positive culturesfor oral Candida may be present in upto 34% of patients. Although thefrequency of clinically apparent infection isconsiderably lower, these infections may requiretreatment withappropriate antifungal therapy or dis- continuancewithAeroBid Inhaler. AeroBid Inhaler is not to be regarded as a bronchodilatorand is not indicated for rapid relief of bronchospasm. Patients should be instructed to contact their physician immediately when episodes of asthmathat are not responsive to bronchodilators occur duringthe course of treatment. During such episodes, patients may requiretherapy with systemic corticosteroids. There is no evidence that control of asthma can beachieved byadministration of thedrug in amounts greaterthan the recom- mended doses, which appear to bethe therapeutic equivalent of approximately 10 mg/day of oral prednisone. Theoretically, the use of inhaled corticosteroids with altemate day prednisone systemic treatment should beaccompanied by more HPA right oi TARGET suppression than a therapeutically equivalent regimen of eitheralone. Transfer of patients from systemic steroid therapyto AeroBid Inhaler may unmask allergic conditions previously suppressed by the systemic steroid therapy, e.g., rhinitis, conjunctivitis, and eczema.

The long-term effects of the drug in human subjects are still unknown. In particular, the local effects of the agent on develop- mental or immunologic processes in the mouth, pharynx, trachea, and lung are unknown.
