What the FDA labels say about taking them together
Aspirin/dipyridamole and salicylic acid
Aspirin/dipyridamole's FDA label of January 5, 2026 names salicylic acid in its drug interactions section; the salicylic acid label PlainMeds reads does not name aspirin/dipyridamole. The aspirin/dipyridamole label: “Anticonvulsants Salicylic acid can displace protein-bound phenytoin and valproic acid, leading to a decrease in the total concentration of phenytoin and an increase in serum valproic acid levels.”
