What this interaction means in plain words

Alteplase and Salicylates can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Why it happens

Salicylates may weakly inhibit platelet function and injure the GI mucosa, adding to fibrinolysis-related bleeding.

What to do
