A synthetic corticosteroid, prednisone acts on the glucocorticoid receptor to suppress inflammation and dampen overactive immune responses. It is prescribed across a broad range of conditions, from asthma and allergic reactions to arthritis, autoimmune diseases, and certain cancers. Structurally it is a pregnane derivative with the molecular formula C21H26O5, marketed under names including Deltasone, Rayos, and Sterapred. Prolonged use affects bone density, blood glucose, and immune function, so extended courses are accompanied by monitoring. Its potency and versatility have made it one of the most widely used systemic steroids in clinical medicine.

Corticosteroids have a complex and variable interaction with warfarin; high doses may increase bleeding risk via GI mucosal effects while also affecting clotting factor synthesis.

Supraphysiologic doses of corticosteroids such as prednisone can suppress TSH secretion and reduce T4-to-T3 conversion, complicating thyroid function interpretation during steroid courses.

Combining ibuprofen with corticosteroids dramatically increases the risk of GI ulcers and hemorrhage beyond the risk of either agent alone.

                                Prednisone + Aspirin
                            
                        

                        
                        
Prednisone may increase salicylate clearance, reducing aspirin's anti-inflammatory efficacy, and combined GI toxicity is substantially increased.

                                Prednisone + Metformin
                            
                        

                        
                        
Prednisone causes dose-dependent hyperglycaemia that can overcome metformin's glucose-lowering capacity, resulting in poorly controlled blood glucose, particularly postprandially.

                                Prednisone + Pembrolizumab
                            
                        

                        
                        
Prednisone at immunosuppressive doses may blunt pembrolizumab's anti-tumour efficacy by dampening the T-cell responses required for checkpoint inhibitor activity.
