This preparation may be administered by intravenous injection, by intravenous infusion, or by intramuscular injection, the preferred method for initial emergency use being intravenous injection. Following the initial emergency period, consideration should be given to employing a longer acting injectable preparation or an oral preparation.

Therapy is initiated by administering A-Hydrocort sterile powder intravenously over a period of 30 seconds (eg, 100 mg) to 10 minutes (eg, 500 mg or more). In general, high-dose corticosteroid therapy should be continued only until the patient’s condition has stabilized − usually not beyond 48 to 72 hours. Although adverse effects associated with high-dose, short-term corticoid therapy are uncommon, peptic ulceration may occur. Prophylactic antacid therapy may be indicated.

When high-dose hydrocortisone therapy must be continued beyond 48-72 hours, hypernatremia may occur. Under such circumstances it may be desirable to replace hydrocortisone sodium succinate with a corticoid such as methylprednisolone sodium succinate which causes little or no sodium retention.

The initial dose of A-Hydrocort sterile powder is 100 mg to 500 mg, depending on the severity of the condition. This dose may be repeated at intervals of 2, 4 or 6 hours as indicated by the patient’s response and clinical condition. While the dose may be reduced for infants and children, it is governed more by the severity of the condition and response of the patient than by age or body weight but should not be less than 25 mg daily.

Patients subjected to severe stress following corticosteroid therapy should be observed closely for signs and symptoms of adrenocortical insufficiency.

Corticoid therapy is an adjunct to, and not a replacement for, conventional therapy.

Preparation of Solutions

100 mg − For intravenous or intramuscular injection, prepare solution by aseptically adding not more than 2 mL of Bacteriostatic Water for Injection or Bacteriostatic Sodium Chloride Injection to the contents of one vial. Further dilution is not necessary for intravenous or intramuscular injection. For intravenous infusion, first prepare solution by adding not more than 2 mL of Bacteriostatic Water for Injection to the vial; this solution may then be added to 100 to 1000 mL of the following: 5% dextrose in water (or isotonic saline solution or 5% dextrose in isotonic saline solution if patient is not on sodium restriction). In cases where administration of a small volume of fluid is desirable, 100 mg of hydrocortisone sodium succinate may be added to 50 mL of the above diluents. The resulting solutions are stable for at least 4 hours and may be administered either directly or by IV piggyback.

When reconstituted as directed, pH’s of the solutions range from 7 to 8 and the tonicities are: 100 mg vial, .36 osmolar. (Isotonic saline = .28 osmolar.)
