Prednisone 20 Mg Explained: Medical Indications, Dosages, and Real Side Effects
Short courses of prednisone 20 mg produce manageable, predictable shifts in daily physiology. Patients frequently report increased appetite, elevated energy levels, mild fluid retention, gastrointestinal irritation, and difficulty sleeping. Mood alterations, ranging from mild euphoria to unprovoked irritability or anxiety, occur in roughly 15% to 28% of patients receiving systemic doses at or above 20 mg.
When systemic steroid therapy extends into months, adverse side effects shift toward structural metabolic changes. Prednisone increases hepatic gluconeogenesis and induces peripheral insulin resistance, driving fasting blood glucose up and triggering steroid-induced diabetes in vulnerable individuals. It promotes mineralocorticoid-driven sodium reabsorption, worsening pre-existing hypertension.
Long-term regimens also interfere with osteoblast activity while accelerating bone reabsorption, elevating the risk of osteopenia and osteoporosis. Patients may develop cushingoid fat redistribution, showing up as rounded facial puffiness (moon face), fat accumulation between the shoulders (buffalo hump), and central abdominal weight gain paired with fragile skin and easy bruising.
