Summary
Rivastigmine increases gastric acid secretion, and salicylates can irritate the gastric lining and affect platelet function, so combining them may raise the risk of GI ulceration and bleeding. The risk is smaller with non-acetylated salicylates than with aspirin.
What this interaction means in plain words
Rivastigmine 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
Additive gastrointestinal risk from cholinergic acid stimulation and salicylate mucosal irritation.
What to do
Watch for dyspepsia, melena and anemia. Consider gastroprotection in patients with prior ulcer disease or advanced age.
