My husband has had 2 severe cases of pancreas. He has also been prescribed creon and sadly it is very expensive. $480 for one month and $150 for 3 months with insurance after deductible has been made. I suggest checking Amazon pharmacy, goodrx, Mark Cubans pharmacy, and if it is still too expensive you can contact the manufacturer to see if you qualify for a reduced price. I was also going to try a Canadian pharmacy.
Best wishes for you.
