What the FDA labels say
From the Butalbital, aspirin, and caffeine label · effective 2026-05-11
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.
From the Methylprednisolone (Depo-Medrol) label · effective 2026-01-21
Hepatic Enzyme Inducers (e.g., barbiturates, phenytoin, carbamazepine, rifampin) : Drugs which induce cytochrome P450 3A4 enzyme activity may enhance the metabolism of corticosteroids and require that the dosage of the corticosteroid be increased.
Nonsteroidal anti-inflammatory drugs (NSAIDs) : Concomitant use of aspirin (or other nonsteroidal anti-inflammatory agents) and corticosteroids increases the risk of gastrointestinal side effects.
The clearance of salicylates may be increased with concurrent use of corticosteroids.
Aspirin should be used cautiously in conjunction with concurrent use of corticosteroids in hypoprothrombinemia.
