NSAIDs including aspirin and salicylates: Increased risk of gastrointestinal side effects.

CYP 3A4 Inducers (e.g., Barbiturates, Phenytoin, Carbamazepine, and Rifampin) Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance the metabolism of corticosteroids and require that the dosage of the corticosteroid be increased.

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) Including Aspirin and Salicylates Concomitant use of aspirin or other nonsteroidal anti-inflammatory drugs and corticosteroids increases the risk of gastrointestinal side effects.

The clearance of salicylates may be increased with concurrent use of corticosteroids; this could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when corticosteroid is withdrawn.

Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia.

In patients receiving concomitant corticosteroids and chronic use of aspirin, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
