Dosage and administration DOSAGE AND ADMINISTRATION Standard tests for verification of adrenal responsiveness to corticotropin may utilize as much as 80 units as a single injection or one or more injections of a lesser dosage. Verification tests should be performed prior to treatment with corticotropins. The test should utilize the route(s) of administration proposed for treatment. Following verification dosage should be individualized according to the disease under treatment and the general medical condition of each patient. Frequency and dose of the drug should be determined by considering severity of the disease, plasma and urine corticosteroid levels and the initial response of the patient. Only gradual change in dosage schedules should be attempted, after full drug effects have become apparent. This product may be administered subcutaneously or intramuscularly with the vial and subcutaneously with the prefilled syringe. In the treatment of acute exacerbations of multiple sclerosis daily subcutaneous or intramuscular doses of 80-120 units for 2-3 weeks. The chronic administration of more than 40 units daily may be associated with uncontrollable adverse effects. When reduction in dosage is indicated this should be accomplished gradually by either reducing the amount of each injection, or administering injections at longer intervals, or by a combination of both of the above. During reduction of dosage, careful consideration should be given to the disease being treated, the general medical condition of the patient and the duration over which corticotropin was administered. Important Administration Instructions • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Purified Cortrophin Gel is a clear, light amber liquid gel at room temperature. Do not use if the solution is discolored or cloudy or the solution contains particulate matter. • Purified Cortrophin Gel will be a solid gel when refrigerated and needs to be warmed to a liquid gel before administration. o For Purified Cortrophin Gel vials warm by rolling between your hands for a few minutes. o For Purified Cortrophin Gel prefilled syringes remove the carton from the refrigerator and leave at room temperature for 45 minutes. • The recommended injection sites include abdomen, upper thigh, or upper arm. Do not inject within 2 inches of navel. Information for Patients Advise patients and/or caregivers to read the FDA-approved patient information (Instructions for Use). Warnings and cautions WARNINGS Chronic administration of corticotropin may lead to adverse effects which are not reversible. This product should not be administered for treatment until adrenal responsiveness has been verified with the route of administration which will be utilized during treatment, intramuscularly or subcutaneously. A rise in urinary and plasma corticosteroid values provides direct evidence of a stimulatory effect. Although the action of corticotropin is similar to that of exogenous adrenocortical steroids the quantity of adrenocorticoid may be variable. In patients who receive prolonged corticotropin therapy the additional use of rapidly acting corticosteroids before, during and after an unusual stressful situation is indicated. Masking Symptoms of Other Diseases Corticotropin may only suppress symptoms and signs of chronic disease without altering the natural course of the disease. Immunogenicity Potential Purified Cortrophin Gel is immunogenic. Limited available data suggest that a patient may develop antibodies to Purified Cortrophin Gel after chronic a
