I am sorry that your question was unanswered for long.
It seems that you are offline, so I am writing you the answer. You may ask follow up questions, once you are online.
There is a small chance of the side effects / adverse effects you have mentioned. The chance is 3-5%. But there is no way to assess the risk in an individual, before starting the medication, unfortunately. Thus initial monitoring for about two weeks would be required, once you start Creon. If you tolerate it for this duration, chance of adverse effects after that duration in quite negligible.
Just a word about the various investigations done for the chronic pancreatitis or pancreatic insufficiency (I am sure your gastroenterologist must have got them done):
1) serum trypsin
2) serum calcium and triglyceride levels.
3) genetic mutations in cationic trypsinogen and CFTR.
4) serum amylase and lipase levels.
5) Assays of fecal chymotrypsin and human pancreatic elastase 1.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
