Hi and welcome to Healthcaremagic. I understand your concerns and I will try to help you as much as I can. There is no scientific data to support this thesis that Naprosyn is causing pancreatitis. If there are no usual risk factors such as alcohol or biliary stones then some less common may be considered such as hypercaciemia, hyperlipidemia, metabolic imbalance, smoking or infection. Sometimes even genetic factors may play role in its development. In most cases, chronic form can be regulated by medications which include insuline supplements and enzymes for digestion Also alcohol is forbidden in these cases and you should eat less fatty food, less sugar and more vegetables and boiled food. Also, avoid citotoxic medications such as azatioprin or steroids. If there is no improvement then surgical therapy may be considered and include drainage procedures or pancreas resection. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
