similar drugs: The active ingredient in pepto, bismuth subsalicylate, is chemically very similar to Aspirin (acetylsalicylic acid). Taking the two together could increase your risk for side effects like bleeding in your stomach. This is especially true if you have clotting problems like von willibrand factor deficiency.

? Risk for toxicity: Aspirin (acetylsalicylic acid) and pepto-bismol (bismuth subsalicylate) are both salicylates. Taking both may increase the risk for toxicity.
