Hi Laura, Good question. Actually, "Bufferin" aspirin is aspirin with antacid already mixed in to help prevent stomach irritation. It is basically like taking an aspirin and a Tums tablet together.
However, 2 things:
1) Do not take ENTERIC coated aspirin with an antacid. The coating requires an acidic environment in order to remain stable until it passes through the stomach. Antacids will cause the coating to dissolve too soon.
2) Understand that the direct irritation of aspirin on the stomach is only a part of the problem. Aspirin works by reducing the production of prostaglandins, which help protect the stomach. Antacids wont prevent this.
If used for chronic pain, I recommend using Enteric coated aspirin without antacid.
Awesome! Just the answer I was looking for. Thanks, pharmacist! I don't take aspirin for chronic pain, but I will make sure to get Enteric coated aspirin in the future (not sure what I have now). Thanks again! Cheers!
