Action

Unclear. Reduces inflammation and prevents edema by stabilizing membranes and reducing permeability of leukocytic cells. Suppresses immune system by interfering with antigen-antibody interactions of macrophages and T cells.

Off-label uses

• Lupus nephritis

Pneumocystis jiroveci pneumonia in AIDS patients

Contraindications

• Hypersensitivity to drug or its component

• Systemic fungal infections

• Use in premature infants (with sodium succinate form, which contains benzyl alcohol)

Precautions

Use cautiously in:

• cardiovascular, hepatic, renal, or GI disease; active untreated infections; thromboembolitic tendency; idiopathic thrombocytopenic purpura; osteoporosis; myasthenia gravis; hypothyroidism; glaucoma; ocular herpes simplex; vaccinia or varicella; seizure disorders; metastatic cancer

• pregnant or breastfeeding patients

• children.

Administration

• As needed and prescribed, give prophylactic antacids to prevent peptic ulcers in patients receiving high doses.

• When methylprednisolone acetate is substituted for oral form, know that I.M. dosage should equal oral dosage and should be given once daily.

• Know that methylprednisolone acetate is not for I.V. use. It may be given I.M. or by intra-articular, intralesional, or soft-tissue injection.

• Be aware that methylprednisolone sodium succinate may be given I.M. or I.V. Reconstitute with bacteriostatic water for injection containing 0.9% benzyl alcohol, per manufacturer's instructions.

• In long-term methylprednisolone therapy, alternate-day therapy should be considered.

• For direct I.V. injection, inject each 500-mg dose over 2 to 3 minutes or more. For I.V. infusion, further dilute in compatible I.V. solution (such as 5% dextrose, 0.9% sodium chloride, or 5% dextrose in 0.9% sodium chloride injection) and give over 10 to 20 minutes.

• Maintain patient on lowest effective dosage, to minimize adverse effects.

Patient monitoring

• Monitor fluid and electrolyte balance, weight, and blood pressure.

• With long-term or high-dose use, assess for cushingoid effects, such as moon face, central obesity, acne, abdominal striae, hypertension, osteoporosis, myopathy, hyperglycemia, fluid and electrolyte imbalances, and increased susceptibility to infection.

Check for signs and symptoms of steroid-induced psychosis (delirium, euphoria, insomnia, mood swings, personality changes, and depression).

• Monitor growth and development in children on prolonged therapy.

• Know that therapy beyond 6 months increases risk of osteoporosis. Obtain baseline bone density mass, and provide teaching about lifestyle factors (such as weight-bearing exercise, proper diet, moderation of alcohol intake, and smoking cessation) and possible need for calcium, vitamin D, or bisphosphonate therapy.

• With long-term use, withdraw drug gradually.

After dosage reduction or drug withdrawal, monitor patient for signs and symptoms of adrenal insufficiency.

Patient teaching

• Tell patient to take with food to minimize GI upset.

• Advise patient on chronic therapy to have periodic eye exams and to carry medical identification that states he's taking drug.

• Inform patient that drug increases risk for infection. Urge him to avoid exposure to people with infections such as measles and chickenpox. Tell him to contact prescriber if exposure occurs.

• Advise patient to report unusual weight gain, swelling, muscle weakness, black tarry stools, vomiting of blood, menstrual irregularities, sore throat, fever, or infection.

Tell patient to immediately report signs or symptoms of adrenal insufficiency (including fatigue, appetite loss, nausea, vomiting, diarrhea, weight loss, weakness, and dizziness) after dosage reduction or drug withdrawal.

• Advise diabetic patient to monitor blood glucose level carefully.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, herbs, and behaviors mentioned above.
