Drug Interactions
Prednisone has wide-ranging effects on metabolism and immune function, leading to many clinically relevant drug interactions.
- NSAIDs (e.g., ibuprofen, naproxen, aspirin): Substantially increase the risk of gastric ulcers and GI bleeding. Avoid combination when possible; consider a PPI for gastroprotection if both are needed.
- Anticoagulants (warfarin, DOACs): Variable effects on INR and additive bleeding risk through GI mucosal injury. Monitor INR more frequently after starting or stopping prednisone.
- CYP3A4 inducers (rifampin, phenytoin, carbamazepine, phenobarbital): Accelerate prednisone metabolism, reducing effectiveness. Higher prednisone doses may be needed.
- CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin): Increase prednisone exposure and risk of corticosteroid side effects. Monitor for excess effect.
- Antidiabetic agents (insulin, metformin, sulfonylureas): Prednisone causes insulin resistance and hyperglycemia. Diabetic patients usually need increased antidiabetic doses during steroid therapy and reductions during the taper.
- Live vaccines (MMR, varicella, zoster live, intranasal influenza, yellow fever): Generally contraindicated when prednisone exceeds 20 mg/day for 2 weeks or longer because of suppressed vaccine response and infection risk. Inactivated vaccines remain appropriate.
- Loop and thiazide diuretics: Additive potassium loss; monitor serum potassium during prolonged combined use.
