    Corticosteroids, including EMFLAZA, readily cross the placenta. Adverse developmental outcomes, including orofacial clefts (cleft lip, with or without cleft palate ) and intrauterine growth restriction , and decreased birth weight, have been reported with maternal use of corticosteroids, including EMFLAZA, during pregnancy. Some epidemiologic studies report an increased risk of orofacial clefts from about 1 per 1000 infants to 3 to 5 per 1000 infants; however, a risk for orofacial clefts has not been observed in all studies. Intrauterine growth restriction and decreased birth weight appear to be dose-related; however, the underlying maternal condition may also contribute to these risks (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the . general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

    In cerebral edema , dexamethasone sodium phosphate injection is generally administered initially in a dosage of 10 mg intravenously followed by 4 mg every six hours intramuscularly until the symptoms of cerebral edema subside. Response is usually noted within 12 to 24 hours and dosage may be reduced after two to four days and gradually discontinued over a period of five to seven days. For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with either dexamethasone sodium phosphate injection or dexamethasone tablets in a dosage of 2 mg two or three times daily may be effective.

    There is concern that P-glycoprotein mediated efflux contributes to steroid resistance. Therefore, this study examined bidirectional corticosteroid transport and induction capabilities for P-glycoprotein (P-gp) to understand which of the systemic and inhaled corticosteroids interacted with P-gp to the greatest extent. Hydrocortisone, prednisolone, prednisone, methylprednisolone, and dexamethasone represented systemically active drugs, while fluticasone propionate, beclomethasone dipropionate, ciclesonide and budesonide represented inhaled corticosteroids. Aldosterone and fludrocortisone represented mineralocorticoids. All drugs were detected using individually optimised HPLC protocols. Transport studies were conducted through Caco-2 monolayers. Hydrocortisone and aldosterone had efflux ratios below , while prednisone showed a P-gp mediated efflux ratio of only compared to its active drug, prednisolone, with an efflux ratio of . Dexamethasone and beclomethasone had efflux ratios of and respectively, while this increased to for methylprednisolone. Fluticasone showed an efflux ratio of . Protein expression studies suggested that all of the inhaled corticosteroids were able to induce P-gp expression, from to 2 times control levels. Most of the systemic corticosteroids had higher passive permeability (>20×10(-6) cm/s) compared to the inhaled corticosteroids (>5×10(-6) cm/s), except for budesonide, with permeability similar to the systemic corticosteroids. Inhaled corticosteroids are not transported by P-gp to the same extent as systemic corticosteroids. However, they are able to induce P-gp production. Thus, inhaled corticosteroids may have greater interactions with other P-gp substrates, but P-gp itself is less likely to influence resistance to the drugs.

    • Prevent asthma symptoms from occurring
    • Can reduce and/or prevent:
      • Inflammation and scarring in the airways
      • Tightening of the muscle bands around the airways (bronchospasm)
    • Do not show immediate results, but work slowly over time
    • Should be taken daily, even when you are not having symptoms
    • Should NOT be used to relieve immediate asthma symptoms.

    Back to top A Note about Long-Term Controller Medicines in Children According to the National Asthma Education and Prevention Program at the National Institutes of Health, long-term controller medicines should be considered when infants or young children have had three or more episodes of wheezing in the previous 12 months and who are at an increased risk of developing asthma because of their own or their parents' history of allergic diseases.

    They also recommend long-term controller medicines for children who need short-acting bronchodilators (rescue medicines) more than twice a week or have had severe asthma symptoms less than six weeks apart. Without a controller medicine, the underlying inflammation will continue to cause more asthma symptoms.
