Side effects of Pepto-Bismol

You’ve probably never heard of bismuth subsalicylate, but you have probably used it or bought it more than once in your life time.   This intimidating compound is what we know as the pink stuff, Pepto-Bismol.  Pepto-Bismol is very common over-the-counter medication, which comes in tablet or liquid form, used to cope with heartburn, nausea, indigestion and any other upset stomach problems. This medication is an antidiarrheal medication that decreases intestinal inflammation, fluid movement and electrolyte movement in the bowels and digestive system. It used to combat diarrhea, but the mechanism of how exactly it does do, is still a bit unclear.  It is thought that the chemical bismuth that is in Pepto-Bismol has a type of antibiotic affect, while the salicylate in the medication is thought to havean antacid effect.

Some ways to avoid the possible negative side effects of Pepto-Bismol:

Knowing what drugs interact with Pepto-Bismol can help you avoid the negative effects of the medication.  Obviously, if you are aware that you are allergic to the bismuth medication, it is wise to avoid it.  Similarly, if you start to develop any uncharacteristic symptoms or negative side effects of Pepto-Bismol, you should stop taking it. If you are allergic to salicylates, or any products related to Pepto-bismol, you shouldn’t take it either, as you are at a higher risk for negative reaction.  If you are on other medications and are unsure if it interacts with Pepto-Bismol, then go over this with your doctor or pharmacist to make sure it is safe to take them together.
