• Because of possible physical incompatibilities, methylprednisolone acetate injectable suspension should not be diluted or mixed with other solutions
• The initial dosage of parenterally administered methylprednisolone acetate injectable suspension will vary from 4 mg to 120 mg, depending on the specific disease entity being treated
• However, in certain overwhelming, acute, life-threatening situations, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages
• It Should Be Emphasized that Dosage Requirements Are Variable and Must Be Individualized on the Basis of the Disease Under Treatment and the Response of the Patient
• After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small decrements at appropriate time intervals until the lowest dosage which will maintain an adequate clinical response is reached
• Situations which may make dosage adjustments necessary are changes in clinical status secondary to remissions or exacerbations in the disease process, the patient’s individual drug responsiveness, and the effect of patient exposure to stressful situations not directly related to the disease entity under treatment
• In this latter situation, it may be necessary to increase the dosage of the corticosteroid for a period of time consistent with the patient’s condition
• If after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually rather than abruptly

Aminoglutethimide: Aminoglutethimide may lead to a loss of corticosteroid-induced adrenal suppression. Amphotericin B injection and potassium-depleting agents: When corticosteroids are administered concomitantly with potassium depleting agents (e.g., amphotericin B, diuretics), patients should be observed closely for development of hypokalemia. There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure. Antibiotics: Macrolide antibiotics have been reported to cause a significant decrease in corticosteroid clearance (see PRECAUTIONS : Drug Interactions , Hepatic Enzyme Inhibitors ). …

Pregnancy: Teratogenic Effects Corticosteroids have been shown to be teratogenic in many species when given in doses equivalent to the human dose. Animal studies in which corticosteroids have been given to pregnant mice, rats, and rabbits have yielded an increased incidence of cleft palate in the offspring. There are no adequate and well-controlled studies in pregnant women. …

Treatment of acute overdosage is by supportive and symptomatic therapy. For chronic overdosage 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.
