A six-day steroid burst, such as a prednisone or methylprednisolone dose pack, commonly brings insomnia, increased appetite, mood swings or irritability, facial flushing, stomach upset, higher blood sugar, and mild fluid retention, with effects usually strongest during the first high-dose days and fading as the taper winds down. How intensely you feel them depends on several factors, including your dose, the time of day you take it, pre-existing conditions like diabetes or hypertension, and other medications, while warning signs such as severe mood changes, chest pain, vision changes, or new fever deserve prompt medical attention. See the complete answer below for a day-by-day breakdown and important details on what is expected versus what is concerning.

Take a free, instant, online symptom check to put your symptoms in context and get clear guidance on your next steps.
