Prednisone
A widely used corticosteroid that reduces inflammation and calms overactive immune responses, prescribed for conditions ranging from asthma and allergic reactions to arthritis, certain cancers, and autoimmune diseases. Long-term use requires careful monitoring as it can affect bone density, blood sugar, and immune function.

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 may increase salicylate clearance, reducing aspirin's anti-inflammatory efficacy, and combined GI toxicity is substantially increased.
Prednisone causes dose-dependent hyperglycaemia that can overcome metformin's glucose-lowering capacity, resulting in poorly controlled blood glucose, particularly postprandially.
Prednisone at immunosuppressive doses may blunt pembrolizumab's anti-tumour efficacy by dampening the T-cell responses required for checkpoint inhibitor activity.
