In general, pancreatic enzymes are well tolerated at recommended therapeutic doses. Gastrointestinal symptoms appear to be the primary, and most common adverse effect.[Ref]
Fibrosing colonopathy should be suspected in patients who present with obstruction, bloody diarrhea, chylous ascites, or a combination of abdominal pain with chronic diarrhea, inadequate weight gain, or both. Patients with fibrosing colonopathy should have their enzyme dosage reduced to the recommended range of 500 to 2500 units/kg per meal. Surgical intervention is often needed in patients who cannot maintain their nutritional status.[Ref]
Gastrointestinal side effects have included cramping, nausea, abnormal feces, flatulence, abdominal pain, upper abdominal pain, and diarrhea, particularly with high doses. Fibrosing colonopathy has been reported. Animal studies suggest that the fibrosing colonopathy seen in some patients receiving high doses of pancreatic enzymes may be due to a plasticizer (methacrylic acid copolymer) found in some of the enteric coatings. Postmarketing reports have included abdominal distention, abdominal pain, diarrhea, flatulence, constipation, nausea, fibrosing colonopathy, and distal intestinal obstruction syndrome (DIOS).[Ref]
Metabolic side effects reported with high doses of pancreatic enzymes have included hyperuricosuria and hyperuricemia. It appears that both the enzyme product and some undefined aspect of the disease may lead to increased uric acid levels. Postmarketing reports of inadequate control of diabetes mellitus have been reported.[Ref]
Krasinger and colleagues suggest that it may be reasonable to add allopurinol to the pancreatic enzyme treatment regimen in CF patients that have a urine pH of less than 6 and also excrete large amounts of uric acid. The addition of allopurinol may help to protect the renal tubules from long-term damage due to uric acid crystallization.[Ref]
Hypersensitivity side effects have included reversible bronchial asthma and nasal rhinitis due to exposure to pancreatic enzyme powder. Postmarketing severe allergic reactions including anaphylaxis, asthma, hives and pruritus have been reported.[Ref]
Nervous system side effects have included several case reports of elevation in intracranial pressure (leading to a bulging cranial fontanelle) in cystic fibrosis children receiving pancreatic enzymes. The adverse effect has been self-limiting without interruption of cystic fibrosis therapy in most cases.[Ref]
Postmarketing side effects include pruritus, urticaria and rash
Postmarketing side effects include recurrence of pre-existing carcinoma.
