INDICATIONS AND USAGE By intravenous or intramuscular injection when oral therapy is not feasible: 1. Endocrine Disorders Primary or secondary adrenocortical insufficiency (hydrocortisone or cortisone is the drug of choice; synthetic analogs may be used in conjunction with mineralocorticoids where applicable; in infancy, mineralocorticoid supplementation is of particular importance). Acute adrenocortical insufficiency (hydrocortisone or cortisone is the drug of choice; mineralocorticoid supplementation may be necessary, particularly when synthetic analogs are used).

Preoperatively, and in the event of serious trauma or illness, in patients with known adrenal insufficiency or when adrenocortical reserve is doubtful. Shock unresponsive to conventional therapy if adrenocortical insufficiency exists or is suspected. Congenital adrenal hyperplasia Nonsuppurative thyroiditis Hypercalcemia associated with cancer 2.

Respiratory Diseases Symptomatic sarcoidosis Berylliosis Fulminating or disseminated pulmonary tuberculosis when used concurrently with appropriate antituberculous chemotherapy. Loeffler’s syndrome not manageable by other means. Aspiration pneumonitis 9.

Hematologic Disorders Acquired (autoimmune) hemolytic anemia. Idiopathic thrombocytopenic purpura in adults (IV only; IM administration is contraindicated). Secondary thrombocytopenia in adults Erythroblastopenia (RBC anemia) Congenital (erythroid) hypoplastic anemia 10.

Neoplastic Diseases For palliative management of: Leukemias and lymphomas in adults Acute leukemia of childhood 11. Edematous States To induce diuresis or remission of proteinuria in the nephrotic syndrome, without uremia, of the idiopathic type or that due to lupus erythematosus. 12.

Miscellaneous Tuberculous meningitis with subarachnoid block or impending block when used concurrently with appropriate antituberculous chemotherapy. Trichinosis with neurologic or myocardial involvement. 13.

Diagnostic testing of adrenocortical hyperfunction. 14. Cerebral Edema associated with primary or metastatic brain tumor, craniotomy, or head injury.

Use in cerebral edema is not a substitute for careful neurosurgical evaluation and definitive management such as neurosurgery or other specific therapy.

DOSAGE AND ADMINISTRATION Dexamethasone sodium phosphate injection, 10 mg/mL– For intravenous and intramuscular injection only. Dexamethasone sodium phosphate injection can be given directly from the vial, or it can be added to Sodium Chloride Injection or Dextrose Injection and administered by intravenous drip. Solutions used for intravenous administration or further dilution of this product should be preservative free when used in the neonate, especially the premature infant.

When it is mixed with an infusion solution, sterile precautions should be observed. Since infusion solutions generally do not contain preservatives, mixtures should be used within 24 hours. DOSAGE REQUIREMENTS ARE VARIABLE AND MUST BE INDIVIDUALIZED ON THE BASIS OF THE DISEASE AND THE RESPONSE OF THE PATIENT.

Intravenous and Intramuscular Injection The initial dosage of dexamethasone sodium phosphate injection varies from 0.5 to 9 mg a day depending on the disease being treated. In less severe diseases doses lower than 0.5 mg may suffice, while in severe diseases doses higher than 9 mg may be required. The initial dosage should be maintained or adjusted until the patient’s response is satisfactory.

If a satisfactory clinical response does not occur after a reasonable period of time, discontinue dexamethasone sodium phosphate injection and transfer the patient to other therapy. After a favorable initial response, the proper maintenance dosage should be determined by decreasing the initial dosage in small amounts to the lowest dosage that maintains an adequate clinical response. Patients should be observed closely for signs that might require dosage adjustment, including changes in clinical status resulting from remissions or exacerbations of the disease, individual drug responsiveness, and the effect of stress (e.g., surgery, infection, trauma).

During stress it may be necessary to increase dosage temporarily. If the drug is to be stopped after more than a few days of treatment, it usually should be withdrawn gradually. When the intravenous route of administration is used, dosage usually should be the same as the oral dosage.

In certain overwhelming, acute, life-threatening situations, however, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages. The slower rate of absorption by intramuscular administration should be recognized. Shock There is a tendency in current medical practice to use high (pharmacologic) doses of corticosteroids for the treatment of unresponsive shock.

The following dosages of dexamethasone sodium phosphate injection have been suggested by various authors: Author Dosage Cavanagh 1 3 mg/kg of body weight per 24 hours by constant intravenous infusion after an initial intravenous injection of 20 mg Dietzman 2 2 to 6 mg/kg of body weight as a single intravenous injection Frank 3 40 mg initially followed by repeat intravenous injection every 4 to 6 hours while shock persists Oaks 4 40 mg initially followed by repeat intravenous injection every 2 to 6 hours while shock persists Schumer 5 1 mg/kg of body weight as a single intravenous injection Administration of high dose corticosteroid therapy should be continued only until the patient’s condition has stabilized and usually not longer than 48 to 72 hours.

Although adverse reactions associated with high dose, short-term corticosteroid therapy are uncommon, peptic ulceration may occur. Cerebral Edema Dexamethasone sodium phosphate injection is generally administered initially in a dosage of 10 mg intravenously followed by four 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 2 mg two or three times a day may be effective. Acute Allergi…
