Methylprednisolone is a synthetic glucocorticoid that binds to specific intracellular glucocorticoid receptors. This complex then translocates to the nucleus, where it modulates gene expression, leading to the synthesis of anti-inflammatory proteins (e.g., lipocortin) and inhibition of pro-inflammatory mediators (e.g., prostaglandins, leukotrienes, cytokines like IL-1, IL-6, TNF-alpha). It also suppresses immune responses by inhibiting leukocyte migration, reducing capillary permeability, and stabilizing lysosomal membranes.

• Live or live-attenuated vaccines (in patients receiving immunosuppressive doses of corticosteroids)

• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin, diltiazem): May significantly increase methylprednisolone levels and adverse effects.
• CYP3A4 inducers (e.g., rifampin, phenytoin, phenobarbital, carbamazepine): May decrease methylprednisolone levels and efficacy.
• NSAIDs (e.g., ibuprofen, naproxen): Increased risk of gastrointestinal ulceration and bleeding.
• Anticoagulants (e.g., warfarin): Effects on anticoagulation can be variable (increased or decreased); monitor INR closely.
• Antidiabetic agents (e.g., insulin, oral hypoglycemics): May increase blood glucose levels, requiring dose adjustment of antidiabetics.
• Diuretics (thiazide, loop): Increased risk of hypokalemia.
• Cardiac glycosides (e.g., digoxin): Increased risk of digitalis toxicity due to hypokalemia.

• Cholestyramine: May decrease absorption of oral corticosteroids (less relevant for IV).
• Cyclosporine: Mutual inhibition of metabolism, leading to increased levels of both drugs and increased risk of seizures.
• Neuromuscular blocking agents (e.g., pancuronium, vecuronium): Prolonged neuromuscular blockade, especially with high-dose corticosteroids.
• Aminoglutethimide: May decrease corticosteroid-induced adrenal suppression.
• Oral contraceptives/Estrogens: May increase corticosteroid levels.

• Antacids: May decrease absorption of oral corticosteroids (less relevant for IV).

• Signs of infection (fever, chills, sore throat, cough, unusual pain)
• Hyperglycemia (increased thirst, urination, fatigue)
• Fluid retention (swelling in ankles/feet, weight gain)
• Gastrointestinal upset (stomach pain, heartburn, black/tarry stools)

• Adrenal insufficiency symptoms upon withdrawal (fatigue, weakness, nausea, vomiting, dizziness)

Methylprednisolone is Pregnancy Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Corticosteroids have been shown to be teratogenic in animals. Human data are limited but suggest no consistent pattern of adverse effects, though some studies suggest an increased risk of oral clefts.

Methylprednisolone is excreted into breast milk in small amounts. It is generally considered compatible with breastfeeding, especially with short-term or low-dose use. For high-dose or prolonged therapy, monitor the infant for adverse effects such as growth suppression or signs of adrenal suppression.

Corticosteroids can cause growth retardation in children. Growth and development should be carefully monitored. Children are also more susceptible to adrenal suppression and increased intracranial pressure. Lowest effective dose for the shortest duration should be used.

Elderly patients may be at increased risk for common corticosteroid adverse effects, including osteoporosis, hypertension, diabetes, fluid retention, and psychiatric disturbances. Close monitoring is recommended.

• High-dose methylprednisolone (pulse therapy) is used for severe, acute inflammatory or autoimmune conditions where rapid immunosuppression is needed.
• Adrenal suppression is a significant risk with prolonged corticosteroid use. Abrupt discontinuation can lead to adrenal crisis. Always taper the dose gradually.
• Patients on corticosteroids are at increased risk of infection, including opportunistic infections. Masking of infection symptoms can occur.
• Monitor for hyperglycemia, especially in diabetic patients or those with risk factors for diabetes.
• Long-term use can lead to osteoporosis, cataracts, glaucoma, and Cushingoid features.
• Administer IV methylprednisolone slowly (over at least 30 minutes for 1gm doses) to avoid adverse effects like bradycardia or arrhythmias.

• Other systemic corticosteroids (e.g., Dexamethasone, Prednisone, Hydrocortisone)
• Immunosuppressants (e.g., Cyclosporine, Azathioprine, Mycophenolate mofetil - depending on indication)
• Biologic agents (e.g., TNF-alpha inhibitors, IL-6 inhibitors - depending on indication)
• Non-steroidal anti-inflammatory drugs (NSAIDs) for less severe inflammatory conditions

If your symptoms or health problems persist or worsen, it is essential to contact your doctor promptly. To ensure safe use, never share your medication with others, and do not take medication prescribed for someone else. Store all medications in a secure location, out of reach of children and pets, to prevent accidental ingestion. Dispose of unused or expired medications properly. Unless instructed to do so by a healthcare professional, do not flush medications down the toilet or pour them down the drain. If you are unsure about the proper disposal method, consult your pharmacist, as they can provide guidance on disposal procedures and potential drug take-back programs in your area. Some medications may come with an additional patient information leaflet, so it is a good idea to check with your pharmacist. If you have any questions or concerns about your medication, discuss them with your doctor, nurse, pharmacist, or other healthcare provider. In the event of a suspected overdose, immediately call your local poison control center or seek emergency medical attention. Be prepared to provide information about the medication taken, the amount, and the time it was taken, as this will aid in receiving appropriate care.
