There are 2 RX meds for EPI- Zenpep and Creon. Creon is cheaper but still expensive. There’s also an OTC enzyme on Amazon (Vital pancreatic enzyme) that has almost the same amount of lipase for digestion of fats, the most important ingredient. I started out using the rxs but have been able to transition to the Vital, one cap with each meal. A low fat diet helps a lot.
I think the recommended dosage for the Rxs is higher than needed for most people.
