Methylprednisolone may be administered by IM or IV or by IV infusion. To administer by IM or IV injection, prepare solution as direction for reconstitution. The desired dose may be administered intravenously over a period of several minutes. When high dose therapy is desired, the recommended dose of Methylprednisolone Sodium Succinate for Injection, USP is 30 mg/kg administered intravenously over at least 30 minutes. This dose may be repeated every 4 to 6 hours for 48 hours. 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.

In other indications, the initial dosage will vary from 10 to 40 mg of Methylprednisolone depending on the clinical problem being treated. The larger doses may be required for short-term management of severe, acute conditions. The initial dose usually should be given intravenously over a period of several minutes. Subsequent doses may be given intravenously or intramuscularly at intervals dictated by the patient’s response and clinical condition. Corticoid therapy is an adjunct to, and not a replacement for conventional therapy.

Dosage must be decreased or discontinued gradually when the drug has been administered for more than a few days. If a period of spontaneous remission occurs in a chronic condition, treatment should be discontinued. Routine laboratory studies, such as urinalysis, two-hour postprandial blood sugar, determination of blood pressure and body weight, and a chest X-ray should be made at regular intervals during prolonged therapy. Upper GI X-rays are desirable in patients with an ulcer history or significant dyspepsia.

In pediatric patients, the initial dose of Methylprednisolone may vary depending on the specific disease being treated. The initial dose is 0.11-1.6 mg/day in three or four divided doses. Dosage may be reduced for infants and children but should be governed more by the severity of the condition and response of the patient than by age or size but it should not be less than 0.5 mg per kg every 24 hours.

In the treatment of acute exacerbations of multiple sclerosis daily doses is 160 mg daily for 3 days. Methylprednisolone powder for injection/infusion should be given as an intravenous infusion over at least 30 minutes.

Methylprednisolone Sterile Powder is contraindicated:

• In systemic fungal infections and patients with known hypersensitivity to the product and its constituents.
• For intrathecal administration. Reports of severe medical events have been associated with this route of administration.
• Intramuscular corticosteroid preparations are contraindicated for idiopathic thrombocytopenic purpura.

Fluid and Electrolyte Disturbances: Sodium retention, fluid retention, congestive heart failure in susceptible patients, potassium loss, hypokalemic alkalosis, hypertension.

Musculoskeletal: Muscle weakness, steroid myopathy, loss of muscle mass, severe arthralgia, vertebral compression fractures, aseptic necrosis of femoral and humeral heads, pathologic fracture of long bones, osteoporosis.

Gastrointestinal: Peptic ulcer with possible perforation and hemorrhage, pancreatitis, abdominal distention, and ulcerative esophagitis.

Dermatologic: Impaired wound healing, thin fragile skin, petechiae and ecchymoses, facial erythema, increased sweating, may suppress reactions to skin tests.

Neurological: Increased intracranial pressure with papilledema (pseudo-tumor cerebri) usually after treatment, convulsions, vertigo, headache.

Endocrine: Development of Cushingoid state, suppression of growth in children, secondary adrenocortical and pituitary unresponsiveness, particularly in times of stress, as in trauma, surgery or illness, menstrual irregularities, decreased carbohydrate tolerance, manifestations of latent diabetes mellitus, increased requirements for insulin or oral hypoglycemic agents in diabetics.

Ophthalmic: Posterior subcapsular cataracts, increased intraocular pressure, glaucoma, exophthalmos.

Others: Negative nitrogen balance due to protein catabolism.

The following additional adverse reactions are related to parenteral corticosteroid therapy: hyperpigmentation or hypopigmentation, subcutaneous and cutaneous atrophy, sterile abscess, anaphylactic reaction with or without circulatory collapse, cardiac arrest, bronchospasm, urticaria, nausea and vomiting, cardiac arrhythmias; hypotension or hypertension.

Overdose Effects

Treatment of acute over dosage is by supportive and symptomatic therapy. For chronic over dosage in the face of severe disease requiring continuous steroid therapy, the dosage of the corticosteroid may be reduced only temporarily or alternate day treatment may be introduced.

Methylprednisolone, like many other steroid formulations, is sensitive to heat. Therefore, it should not be autoclaved when it is desirable to sterilize the exterior of the vial. The lowest possible dose of corticosteroid should be used to control the condition under treatment. When reduction in dosage is possible, the reduction should be gradual. Since complications of treatment with glucocorticoids are dependent on the size of the dose and the duration of treatment a risk/benefit decision must be made in each individual case as to dose and duration of treatment and as to whether daily or intermittent therapy should be used. For chronic conditions, discontinuation of corticosteroids may result in clinical improvement.

Use in Special Populations

Pediatric Use: The adverse effects of corticosteroids in pediatric patients are similar to those in adults. Like adults, pediatric patients should be carefully observed with frequent measurements of blood pressure, weight, height, intraocular pressure and clinical evaluation for the presence of infection, psychosocial disturbances, thromboembolism, peptic ulcers, cataracts and osteoporosis. Pediatric patients who are treated with corticosteroids by any route, including systemically administered corticosteroids, may experience a decrease in their growth velocity. In order to minimize the potential growth effects of corticosteroids, pediatric patients should be titrated to the lowest effective dose.

Geriatric Use: Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, refecting the greater frequency of decreased hepatic, renal or cardiac function and of concomitant disease or other drug therapy.

Pregnancy & Lactation

Pregnancy: Corticosteroids have been shown to be teratogenic in many species when given in doses equivalent to the human dose. There are no adequate and well-controlled studies in pregnant women. Corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Infants born to mothers who have received corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism.

Lactation: Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from corticosteroids, a decision should be made whether to continue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
