Patients should not be challenged if they have chronic medical the event of anaphylaxis/treatment of anaphylaxis. Examples of such conditions include unstable angina pectoris, cardiac disease or dysrhythmias, severe chronic lung disease.\n* Pregnancy should be ruled out by testing or based on history (e.g, before menarche) as appropriate\n* Use of oral corticosteroids. Inhaled and topical steroids or anti-inflammatory medications, such as calcineurin inhibitors or leukotriene antagonists and b-agonists, used at the lowest doses possible and on an established schedule by using fixed doses of medication to maintain a low and stable baseline of atopic disease.
