Zenpep
Zenpep (pancrelipase) is a prescription medication used for children and adults with exocrine pancreatic insufficiency (EPI), a condition where the pancreas doesn’t make enough enzymes to digest food. It contains pancreatic enzymes that help break down fats, carbohydrates, and proteins so your body can absorb nutrients. You take the capsule by mouth with every meal and snack, and your dose is based on your weight, age, and diet. Common side effects include cough, headache, and feeling full quickly. Right now, there isn’t a generic version of Zenpep (pancrelipase) available.

How Zenpep (pancrelipase) works
Zenpep (pancrelipase) is an enzyme replacement therapy. It works by giving your body the digestive enzymes that it can't make enough of on its own. Specifically, it replaces three pancreatic enzymes (lipase, amylase, and protease), which help you break down fats, proteins, and carbohydrates in your food. By improving digestion, Zenpep (pancrelipase) helps your body absorb nutrients better and can reduce stomach problems like bloating and fatty stools.

What are the risks and warnings for Zenpep (pancrelipase)?
Zenpep (pancrelipase) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Scarring in the colon (fibrosing colonopathy)
Risk factors: High dose of Zenpep (pancrelipase) | Long-term use of Zenpep (pancrelipase) | Children with cystic fibrosis
Though rare, Zenpep (pancrelipase) can sometimes cause serious scarring in the colon, called fibrosing colonopathy, especially if you take high doses or use it for a long time. This problem has been reported most often in children with cystic fibrosis.
To lower your risk, take Zenpep (pancrelipase)] only as directed by your prescriber and never more than recommended. Watch for symptoms like stomach pain, bloating, constipation, diarrhea, nausea, or vomiting, and let your prescriber know right away if they happen.
Mouth irritation
Risk factors: Crushing or chewing Zenpep (pancrelipase) capsules | Mixing Zenpep (pancrelipase) capsule contents in non-acidic foods
It's important that you swallow Zenpep (pancrelipase) capsules whole. Crushing or chewing the capsules, or mixing them with non-acidic foods, can break down their protective coating. This can cause the enzymes to release too early, which can irritate your mouth and make the medication work less well.
If you have trouble swallowing Zenpep (pancrelipase) capsules, you can open them and sprinkle the contents onto a small amount of acidic soft food, like applesauce, bananas, or pears.
After taking Zenpep (pancrelipase), drink plenty of liquid such as juice or water to make sure no medication stays in your mouth. Babies should drink breast milk or formula after taking it. For babies under 12 months or anyone unable to swallow whole capsules, check the mouth to make sure no medication is left behind and that there’s no irritation.
High uric acid levels
Risk factors: Gout | Kidney problems | High uric acid levels | High dose of Zenpep (pancrelipase)
Zenpep (pancrelipase) can raise the uric acid levels in your blood, which can increase your risk for gout. If you already have gout, kidney problems, or high uric acid levels, your prescriber might check your blood during treatment to keep you safe. Watch for symptoms such as sudden joint pain, swelling, redness, warmth, or stiffness, especially in the big toe, ankle, or knee, and let your prescriber know if they occur.
Possible risk of infection
Though very rare, Zenpep (pancrelipase) might carry a small risk of viral infection because it’s made from pig pancreas tissue. The chance of this happening is extremely low since the medication goes through strict manufacturing processes to remove or kill viruses. No cases of infection from Zenpep (pancrelipase)] have ever been reported. If you’re concerned about this risk, talk with your care team.
Severe allergic reaction
Risk factors: Allergy to pork products
Severe allergic reactions have been reported with Zenpep (pancrelipase), including anaphylaxis, asthma, hives, and itching. Because this medication is made from pig pancreas tissue, let your prescriber know if you have an allergy to pork products. Your care team will then decide if the benefits of taking Zenpep (pancrelipase)] outweigh the risks for your health.
