Pertzye (lipase, protease and amylase) is a combination of enzymes indicated for the treatment of exocrine pancreatic insufficiency due to cystic fibrosis or other conditions. Common side effects of Pertzye include:

  • irritation of the inside of the mouth
  • increased uric acid levels in the blood
  • diarrhea
  • indigestion
  • upset stomach
  • abdominal pain
  • gas
  • cough, and
  • allergic reactions (trouble breathing, skin rash, itching, or swollen lips)

Pertzye is available in 8,000 and 16,000 lipase units (USP). In children older than 12 months and younger than 4 years and weighing 8 kg or greater, enzyme dosing should begin with 1,000 lipase units/kg of body weight to a maximum of 2,500 lipase units/kg of body weight. In children older than 4 years and older and weighing 16 kg or greater and adults, enzyme dosing should begin with 500 lipase units/kg of body weight to a maximum of 2,500 lipase units/kg of body weight (or less than or equal to 10,000 lipase units/kg of body weight per day), or less than 4,000 lipase units/g fat ingested per day. Pertzye should be taken with a meal or a snack. Pertzye may interact with other drugs. Tell your doctor all medications and supplements you use. Tell your doctor all medications and supplements you use. Pertzye should be given to a pregnant woman only if clearly needed. The risk and benefit of pancrelipase should be considered in the context of the need to provide adequate nutritional support to a pregnant woman with exocrine pancreatic insufficiency. Adequate caloric intake during pregnancy is important for normal maternal weight gain and fetal growth. Reduced maternal weight gain and malnutrition can be associated with adverse pregnancy outcomes. Because many drugs are excreted in human milk, caution should be exercised when Pertzye is administered to a nursing mother.

Pertzye Professional Information


The most serious adverse reactions reported with different pancreatic enzyme products of the same active ingredient (pancrelipase) include fibrosing colonopathy, hyperuricemia and allergic reactions [see WARNINGS AND PRECAUTIONS].

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The short-term safety of PERTZYE was assessed in a randomized, double-blind, placebo-controlled, crossover study of 24 patients, ages 8 to 43 years, with exocrine pancreatic insufficiency due to cystic fibrosis. In this study, patients were randomized to receive PERTZYE at individually titrated doses (not to exceed 2,500 lipase units per kilogram per meal) or matching placebo for 6 to 8 days of treatment, followed by crossover to the alternate treatment for an additional 6 to 8 days. The length of exposure to PERTZYE during this study was 20-28 days, including the treatment period of 6 to 8 days, and the open label titration and transition periods of 7 to 10 days.

The most common adverse reactions ( ≥ 10%) were diarrhea, dyspepsia, and cough. Table 1 enumerates adverse reactions that occurred in at least 2 patients (greater than or equal to 10%) treated with PERTZYE at a higher rate than with placebo.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of PERTZYE. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

This formulation of PERTZYE has been marketed since 2004 under the trademark PANCRECARB®. Two product complaints relating to an adverse drug reaction were reported. A mild allergic reaction (itching and red, blotchy rash on face) was reported by a patient with a known history of allergy to another pancrelipase product, and a dull headache was reported by another patient taking concomitant ursodeoxycholic acid. Both events resolved without sequelae after discontinuation of treatment.

Delayed-and immediate-release pancreatic enzyme products with different formulations of the same active ingredient (pancrelipase) have been used for the treatment of patients with exocrine pancreatic insufficiency due to cystic fibrosis and other conditions, such as chronic pancreatitis. The long-term safety profile of these products has been described in the medical literature. The most serious adverse events include fibrosing colonopathy, distal intestinal obstruction syndrome (DIOS), recurrence of pre-existing carcinoma, and severe allergic reactions including anaphylaxis, asthma, hives, and pruritus. The most commonly reported adverse events were gastrointestinal disorders, including abdominal pain, diarrhea, flatulence, constipation and nausea, and skin disorders, including pruritus, urticaria and rash.
