Upshutter-
Naprosyn and Mobic are both non steroidal anti-inflammatory drugs. Of all the possible side effects they can have, gastrointestinal side effects (pain, gas, diarrhea, nausea, heartburn, etc) are frequent and definitely the most common for both. Looking at the data from their clinical trials, it's hard to discern (unless they are compared to each other in the same trial) which one is more likely to cause diarrhea, but obviously the Mobic isn't agreeing with you.
Am wondering if a slight reduction in dosage will help your bowels and still give you pain relief. Definitely talk to your doctor if it continues.

Hey Zuzu8, thanks for the reply. I'm going to see if it persists....hopefully it doesn't. I REALLY REALLY hope it doesn't. Thanks for the reply, I'm glad someone out there knows what I'm talking about. At first when I had Naprosyn, everyone knew what I was talking about. I guess that one is really popular. After I said Mobic, it seemed like no one had a clue. My doc told me it's like the, "Fancier stuff"....is that true or is it just because it's a lil more expensive?? Anywho, thanks, take care! :wave:
