Cytoprotective agent
Used to reduce the incidence and severity of cardiomyopathy associated with doxorubicin administration in women with metastatic breast cancer who have received a cumulative doxorubicin dose of 300 mg/m2 and for the treatment of extravasation resulting from IV anthracycline chemotherapy
May increase the myelosuppressive effects of chemotherapy

Indicated for anthracycline-induced cardiomyopathy prophylaxis.

For control of severe or incapacitating allergic conditions intractable to adequate trials of conventional treatment in asthma, atopic dermatitis, contact dermatitis, drug hypersensitivity reactions, perennial or seasonal allergic rhinitis, and serum sickness

For the treatment of extravasation resulting from IV anthracycline chemotherapy.

Systemic fungal infection

Documented hypersensitivity

Cerebral malaria

Administration of live or live, attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids

Allergic reactions: Anaphylactoid reaction, anaphylaxis, angioedema

Cardiovascular: Bradycardia, cardiac arrest, cardiac arrhythmias, cardiac enlargement, circulatory collapse, congestive heart failure, fat embolism, hypertension, hypertrophic cardiomyopathy in premature infants, myocardial rupture following recent myocardial infarction, edema, pulmonary edema, syncope, tachycardia, thromboembolism, thrombophlebitis, vasculitis

Dermatologic: Acne, allergic dermatitis, dry scaly skin, ecchymoses and petechiae, erythema, impaired wound healing, increased sweating, rash, striae, suppression of reactions to skin tests, thin fragile skin, thinning scalp hair, urticaria

Endocrine: Decreased carbohydrate and glucose tolerance, development of cushingoid state, hyperglycemia, glycosuria, hirsutism, hypertrichosis, increased requirements for insulin or oral hypoglycemic agents in diabetes, manifestations of latent diabetes mellitus, menstrual irregularities, secondary adrenocortical and pituitary unresponsiveness (particularly in times of stress, as in trauma, surgery, or illness), suppression of growth in pediatric patients

Fluid and electrolyte disturbances: Congestive heart failure in susceptible patients, fluid retention, hypokalemic alkalosis, potassium loss, sodium retention, tumor lysis syndrome

Gastrointestinal: Abdominal distention, elevation in serum liver enzyme levels (usually reversible upon discontinuation), hepatomegaly, increased appetite, nausea, pancreatitis, peptic ulcer with possible perforation and hemorrhage, perforation of the small and large intestine (particularly in patients with inflammatory bowel disease), ulcerative esophagitis

Metabolic: Negative nitrogen balance due to protein catabolism Musculoskeletal: Aseptic necrosis of femoral and humeral heads, loss of muscle mass, muscle weakness, osteoporosis, pathologic fracture of long bones, steroid myopathy, tendon rupture, vertebral compression fractures

Neurological/Psychiatric: Convulsions, depression, emotional instability, euphoria, headache, increased intracranial pressure with papilledema (pseudotumor cerebri) usually following discontinuation of treatment, insomnia, mood swings, neuritis, neuropathy, paresthesia, personality changes, psychic disorders, vertigo

Ophthalmic: Exophthalmos, glaucoma, increased intraocular pressure, posterior subcapsular cataracts, vision blurred

Other: Abnormal fat deposits, decreased resistance to infection, hiccups, increased or decreased motility and number of spermatozoa, malaise, moon face, weight gain

Use with caution in cirrhosis, diverticulitis, myasthenia gravis, peptic ulcer disease, ulcerative colitis, renal insufficiency, pregnancy

Average and large doses of corticosteroids can cause elevation of blood pressure, sodium and water retention, and increased excretion of potassium; these effects are less likely to occur with synthetic derivatives except when used in large doses; dietary salt restriction and potassium supplementation may be necessary; all corticosteroids increase calcium excretion

Literature reports suggest apparent association between use of corticosteroids and left ventricular free wall rupture after recent myocardial infarction; therapy with corticosteroids should be used with great caution in these patients

Corticosteroids can produce reversible hypothalamic-pituitary adrenal (HPA) axis suppression with potential for glucocorticosteroid insufficiency after withdrawal of treatment; adrenocortical insufficiency may result from too rapid withdrawal; may be minimized by gradual reduction of dosage; relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, reinstitute hormone therapy; if patient is receiving steroids already, may increase dosage

Corticosteroids readily cross the placenta

Adverse developmental outcomes including orofacial clefts (cleft lip with or without cleft palate), intrauterine growth restriction, and decreased birth weight have been reported with maternal use of corticosteroids during pregnancy

Pregnancy testing is recommended for females of reproductive potential before initiating treatment

Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects

Advise women not to breastfeed during treatment and for 2 weeks after the last dose

Adults

Maximum dose as a cytoprotective agent is dependent on the doxorubicin dose; Maximum dose as extravasation treatment is 1,000 mg/m2 (up to 2,000 mg).

Geriatric

Maximum dose as a cytoprotective agent is dependent on the doxorubicin dose; Maximum dose as extravasation treatment is 1,000 mg/m2 (up to 2,000 mg).
