I've had a roux-en-y gastric bypass and i've been told to avoid ibuprofen products can i take naprosyn (naproxen) ?

That's an Ibuprofen-: like compound, known as NSAIDS (nonsteroidal anti-inflammatory drug). It's also known as Aleve (naproxen) too OTC. This class produces gastritis or stomach lining irritation and worse without food. So this is why when you are getting gastric bypass surgery, and have little space hold food in, the NSAIDS can wreak havoc on your stomach's lining and cause you pain and distress.

No: Naprosyn is in the same class of medicines as ibuprofen, called NSAIDS. You should avoid other over the counter(OTC)products which are also of the same class: Aleve, (naproxen) Advil, Motrin. You should also avoid Aspirin, and many OTC products that contain Aspirin: Ecotrin, Excedrin. Check labels. You can use Tylenol(acetaminophen) When in doubt check with your physician.
