Pancreatic enzyme replacement
Pancreatin (e.g. Creon) — Replaces digestive enzymes so food can be absorbed in pancreatic insufficiency.

Quick answer
What is Pancreatic enzyme replacement?
Pancreatic enzyme replacement supplies the enzymes that digest fat, protein and starch in people whose pancreas cannot make enough. It allows food to be absorbed and prevents malnutrition.
- How it works: The capsules contain coated digestive enzymes that survive the stomach and release in the small intestine, where they mix with food and break it down so it can be absorbed — doing the job the pancreas can no longer do.
- In practice: In practice pancreatic enzyme replacement is essential in conditions where the pancreas cannot supply enough digestive enzymes — chronic pancreatitis, cystic fibrosis, after pancreatic surgery and in pancreatic cancer — preventing the weight loss, fatty diarrhoea (steatorrhoea) and malnutrition of undigested food.

Pancreatic enzyme replacement supplies the enzymes that digest fat, protein and starch in people whose pancreas cannot make enough. It allows food to be absorbed and prevents malnutrition.
How it works
The capsules contain coated digestive enzymes that survive the stomach and release in the small intestine, where they mix with food and break it down so it can be absorbed — doing the job the pancreas can no longer do.
In practice
In practice pancreatic enzyme replacement is essential in conditions where the pancreas cannot supply enough digestive enzymes — chronic pancreatitis, cystic fibrosis, after pancreatic surgery and in pancreatic cancer — preventing the weight loss, fatty diarrhoea (steatorrhoea) and malnutrition of undigested food. The single most important practical point is timing: the capsules must be taken with every meal and snack (and usually split around larger meals), because the enzymes only work mixed with food — taken apart from food they do nothing. Capsules can be swallowed whole or opened onto soft, non-alkaline food and not crushed or chewed (which would destroy the protective coating), and they are washed down without holding them in the mouth. The dose is matched to symptoms and meal size, and fat-soluble vitamins are often needed alongside.
Examples
Practical use
How to take it & use it well
- Take pancreatin (such as Creon) with every meal and snack, as it only works when mixed with the food you eat.
- Swallow the capsules whole, or open them and sprinkle the contents onto soft, non-alkaline food such as a small amount of apple puree, then swallow without chewing.
- Do not crush or chew the granules, as this stops them working and can irritate the mouth.
- Take them during or just before eating rather than long before or after, and spread them across the meal if it is large or long.
- Drink enough fluids, store as directed, and take any fat-soluble vitamins your clinician recommends, as deficiency is common in these conditions.
Common uses
- Chronic pancreatitis
- Cystic fibrosis
- After pancreatic surgery or in pancreatic cancer
Monitoring
- Weight, symptoms (fatty stools, bloating) and nutritional status
- Fat-soluble vitamin levels where relevant
- Dose adjusted to meals and response
Weighing it up
Advantages & disadvantages
Advantages
- It replaces missing digestive enzymes, helping the body absorb fat and nutrients in conditions like chronic pancreatitis, cystic fibrosis and after pancreatic surgery.
- It can reduce symptoms such as bulky, greasy, hard-to-flush stools, bloating and weight loss.
- Better nutrient absorption supports weight, energy and overall nutrition.
- The capsule contents can be sprinkled onto soft food for those who struggle to swallow capsules whole.
Disadvantages
- It must be taken with every meal and snack, which means dosing many times a day.
- It only works when mixed with food, so timing matters and missed doses with meals reduce its benefit.
- It does not treat the underlying condition and is needed long-term.
- People often still need fat-soluble vitamin supplements because absorption remains imperfect.
Key safety principles
What to watch for
- Take with every meal and snack — the enzymes only work mixed with food.
- Swallow capsules whole, or open onto soft non-alkaline food; do not crush or chew (it destroys the coating).
- Match the amount to meal size and symptoms; fat-soluble vitamins are often needed alongside.
Key interactions
What to avoid or check alongside
- Alkaline foods and crushing or chewing the granules break down the protective coating and stop the enzymes working.
- It has few direct medicine interactions, but very high doses have been linked to bowel problems in some conditions, so stick to advised amounts.
- Taking it without food means it does little, as it needs to mix with a meal to act.
- Tell your clinician about all your treatments so your dose can be matched to your meals and condition.
Patient & carer advice
- Take them with everything you eat — meals and snacks
- Swallow whole or sprinkle onto soft food; do not chew them
- If fatty diarrhoea or weight loss continues, tell us — the amount may need adjusting

Answers
Pancreatic enzyme replacement: frequently asked questions
When should I take my pancreatic enzymes?
Take them with every meal and snack, because they only work when mixed with food. Spread the dose through larger meals as advised.
Can I crush or chew the capsules?
No. Crushing or chewing destroys the special coating and stops the enzymes working, and can irritate your mouth. Swallow capsules whole or sprinkle the contents onto soft, non-alkaline food and swallow without chewing.
What happens if I forget to take them with a meal?
Without enzymes, that meal may not be digested well, which can cause greasy stools, bloating or discomfort. Try to keep them to hand so you remember with each meal and snack.
Why do I need extra vitamins?
These conditions can stop the body absorbing fat-soluble vitamins properly, even with enzyme replacement. Your clinician may recommend supplements to prevent deficiency.
Will the enzymes cure my condition?
No, they replace the enzymes your pancreas no longer makes enough of, but do not treat the underlying problem. They are usually needed long-term.
