Zenpep (pancrelipase) is a type of pancreatic enzyme replacement therapy for people who cannot process food normally. It is manufactured by Nestlé HealthCare Nutrition, Inc. Zenpep was approved in 2009 by the U.S. Food and Drug Administration (FDA) to replace digestive enzymes in patients with conditions such as cystic fibrosis.
If your doctor has prescribed Zenpep to you, you may want to know more about what it is and how it works. Here we’ll explain what Zenpep is used for, how it works, its side effects, and more.
What is Zenpep used for?
Zenpep is a combination of porcine (pig) derived lipases, proteases, and amylases used to treat exocrine pancreatic insufficiency (EPI) due to conditions such as cystic fibrosis, chronic pancreatitis, pancreatic cancer, or gastrointestinal bypass.
How does Zenpep work?
Zenpep is typically used by people who have problems with digesting food because their pancreas doesn’t make enough digestive enzymes. Following activation in the small intestine, Zenpep releases high levels of lipase, amylase, and protease, which help your body break down and digest fats, carbohydrates, and proteins.
What are the most commonly prescribed doses of Zenpep?
- 3,000 USP units of lipase; 10,000 USP units of protease; 14,000 USP units of amylase in a delayed-release capsule
- 5,000 USP units of lipase; 17,000 USP units of protease; 24,000 USP units of amylase in a delayed-release capsule
- 10,000 USP units of lipase; 32,000 USP units of protease; 42,000 USP units of amylase in a delayed-release capsule
- 15,000 USP units of lipase; 47,000 USP units of protease; 63,000 USP units of amylase in a delayed-release capsule
- 20,000 USP units of lipase; 63,000 USP units of protease; 84,000 USP units of amylase in a delayed-release capsule
- 25,000 USP units of lipase; 79,000 USP units of protease; 105,000 USP units of amylase in a delayed-release capsule
- 40,000 USP units of lipase; 126,000 USP units of protease; 168,000 USP units of amylase in a delayed-release capsule
Before taking Zenpep
Before beginning Zenpep, tell your doctor about your medical conditions, including:
- Allergy to pork products

For infants (up to 12 months):
- Give Zenpep before each feeding with formula or breast milk. Open the Zenpep capsule and sprinkle it on some soft foods such as applesauce or pureed fruit. You should give them the mixture immediately and then give them enough liquid to ensure they completely swallowed it. Do not mix the contents of the capsule into their formula or breast milk. You can also sprinkle the contents directly into your infant’s mouth, followed by enough liquid to make sure they swallowed it. Check your infant’s mouth to make sure all of the contents of the capsule were swallowed.
Currently, there are no contraindications for this medication per the manufacturer.
- High doses of pancreatic enzymes can cause a rare bowel disorder called fibrosing colonopathy. You should use caution if your Zenpep dose is higher than 2,500 lipase units/kg of body weight per meal or if it is higher than 10,000 lipase units/kg of body weight per day.
- Do not chew or hold Zenpep capsules or their contents in your mouth as it can cause mouth irritation.
- You should use Zenpep with caution if you have an allergy to gout, kidney impairment or high levels of uric acid, or an allergy to pork products.

There is no drug-related risk of major birth defects, miscarriage, or other adverse effects of Zenpep on the mother or unborn baby. There are no formal studies on the use of Zenpep during lactation.

No, Zenpep does not cause weight gain. In fact, during clinical trials, 6% of patients taking Zenpep lost weight.
How long does it take Zenpep to work?
After taking Zenpep by mouth, it can take as little as 30 minutes for the enzymes to get delivered to the intestines and start digesting fats, carbs, and proteins.
How long can you take Zenpep?
Pancreatic enzyme replacement is typically a long-term therapy. It will depend on the condition causing your pancreas to not make enough digestive enzymes. People who have had their pancreas removed will have to take Zenpep for the rest of their lives.
How long does Zenpep stay in your system?
Zenpep is minimally absorbed into your bloodstream and works in your intestines to help break down your food. It only works for a short period of time so you must take a dose of Zenpep with every meal or snack.
