5 min read

According to the National Institutes of Health, Pancreatic Enzyme Replacement Therapy (PERT) is a safe and effective treatment for exocrine pancreatic insufficiency, a condition where the pancreas doesn't produce enough digestive enzymes [4]. This raises the question for many patients and curious individuals: are pancreatic enzymes safe to take?

Quick Summary

Pancreatic enzyme replacement therapy (PERT) is generally considered safe and effective when used as prescribed. However, high doses or unregulated supplements can pose risks, including a rare bowel disorder called fibrosing colonopathy. Common side effects are typically mild, such as stomach pain and nausea, which can sometimes indicate improper dosing. Always consult a doctor for personalized guidance.

Key Points

Prescribed PERT is safe for medical conditions: When taken as directed under a doctor's supervision, FDA-approved pancreatic enzyme replacement therapy (PERT) is a safe and effective treatment for pancreatic insufficiency [1, 4].
OTC supplements are unregulated: Over-the-counter supplements lack FDA oversight, meaning their content and potency can vary, and their safety is not guaranteed [1, 2].
High doses carry risks: Taking excessively high doses, especially long-term, can increase the risk of a rare, serious bowel disorder called fibrosing colonopathy [4].
Side effects often relate to dosing: Common side effects like stomach pain, diarrhea, and nausea can be symptoms of either the underlying condition or an improper dose, and may require adjustment by a doctor [4].
Alcohol should be avoided: For those with pancreatitis or pancreatic insufficiency, abstaining from alcohol is crucial to prevent further damage and avoid severe pain [5].
Consult a professional: Always speak with a healthcare provider or dietitian before starting any pancreatic enzyme therapy to ensure proper dosage and administration [3].

What are pancreatic enzymes and why are they needed?

Pancreatic enzymes, including lipase, amylase, and protease, are essential for digesting fats, carbohydrates, and proteins [1]. The pancreas produces and secretes these enzymes into the small intestine to facilitate nutrient absorption [4]. For individuals with a condition known as exocrine pancreatic insufficiency (EPI), the pancreas fails to produce or secrete enough of these enzymes, leading to malabsorption of nutrients [4].

Common causes of EPI include chronic pancreatitis, cystic fibrosis, and pancreatic cancer [1]. Without adequate enzyme levels, affected individuals can experience symptoms such as weight loss, bloating, abdominal pain, and fatty stools [1]. Pancreatic enzyme replacement therapy (PERT) is the standard treatment to help these individuals digest food properly and absorb essential nutrients [4].

The Safety of Prescription vs. Supplemental Enzymes

When evaluating the question of whether pancreatic enzymes are safe to take, it's crucial to distinguish between FDA-approved prescription products and unregulated over-the-counter (OTC) supplements. Their safety profiles differ significantly.

Prescription Pancreatic Enzyme Products (PERT)

Regulation: These products, like Creon, Pancreaze, and Zenpep, are FDA-approved, meaning their manufacturing processes, dosage, and efficacy are standardized and closely monitored [2].
Safety Profile: When used under the guidance of a healthcare provider and at the correct dose, PERT is considered likely safe [1, 4]. The side effects are usually mild and may include gastrointestinal issues like stomach pain, nausea, and vomiting [1].
Long-Term Concerns: Long-term use of very high doses, particularly in individuals with cystic fibrosis, has been associated with a rare but serious bowel disorder called fibrosing colonopathy [4]. This risk is why exceeding the prescribed dosage is discouraged and why it is important to not exceed recommended lipase units per kilogram of body weight per day [4].

Over-the-Counter (OTC) Pancreatic Enzyme Supplements

Regulation: As dietary supplements, OTC products are not subject to the same strict FDA oversight as prescription medications [2]. This means there is no guarantee of manufacturing consistency or the accuracy of ingredients listed on the label [2].
Safety Profile: There is insufficient reliable information to confirm the safety or efficacy of these supplements [1, 2]. Because enzyme potency can vary widely between brands and even batches, it is impossible to know for certain what you are taking or if it will be effective [2]. For individuals with a diagnosed condition, relying on these unregulated products is not recommended [3].

Potential Side Effects and How to Manage Them

While PERT is generally well-tolerated, some individuals may experience side effects. It is important to know which symptoms are common and which may warrant medical attention.

Gastrointestinal Distress: Nausea, diarrhea, abdominal pain, and constipation are possible side effects [1]. However, these symptoms are also indicative of the underlying pancreatic insufficiency, and sometimes a low enzyme dose is the real issue [4]. Your doctor or dietitian can help you adjust the dosage to find the right balance.
Hyperuricemia: Increased blood uric acid levels can occur, potentially leading to gout-like symptoms such as joint pain [1]. Your doctor can monitor your uric acid levels if necessary.
Fibrosing Colonopathy: As mentioned, this is a rare but serious bowel disorder associated with very high doses, especially in children with cystic fibrosis [4]. Symptoms include severe abdominal pain, bloating, and vomiting [1]. Call your doctor immediately if you experience these symptoms [1].
Allergic Reactions: In rare cases, individuals may have an allergic reaction, as most enzymes are derived from pork [1]. Symptoms may include a rash, difficulty breathing, or swollen lips [1].

Taking Your Pancreatic Enzymes Correctly

To ensure both safety and effectiveness, proper administration is key. Always follow the instructions from your healthcare provider and the product label.

Best Practices for Taking Enzymes

Take with every meal and snack, including nutritional shakes [1].
Swallow capsules whole with a cool or room-temperature liquid. Do not crush or chew them, as this can deactivate the enzymes and cause mouth irritation [4, 1].
If unable to swallow capsules, open and sprinkle the contents onto a small amount of acidic food like applesauce. Swallow immediately without chewing [1].
Space out capsules throughout a meal, taking the first one with the first bite [1].
Never take enzymes on an empty stomach or with just a hot or plain liquid [1].
Stay hydrated, as recommended doses can be high [4].

Conclusion

For individuals with a diagnosed medical condition causing pancreatic insufficiency, prescribed pancreatic enzyme replacement therapy (PERT) is a safe and effective treatment when taken as directed by a healthcare professional [4]. The potential side effects are typically mild and manageable, and the more serious risks are associated with very high, unmonitored doses [1, 4]. In contrast, the safety and effectiveness of over-the-counter pancreatic enzyme supplements are not reliably established due to a lack of regulatory oversight [1, 2]. Always consult with a doctor or dietitian before starting any enzyme therapy, especially if you have a known pancreatic condition.

How Alcohol Affects Pancreatic Enzyme Therapy

Alcohol is a significant risk factor for pancreatitis, a major cause of pancreatic insufficiency [5]. Continued alcohol consumption can worsen the condition and increase the risk of painful flare-ups [5]. Individuals with chronic pancreatitis, regardless of the cause, are strongly advised to abstain from alcohol completely to prevent further irreversible damage to the pancreas [5]. Therefore, combining alcohol with pancreatic enzyme therapy is not recommended, as it can be counterproductive to the treatment's goals of improving pancreatic function and digestion [5].

Potential Complications of Pancreatic Insufficiency

Ignoring the need for pancreatic enzyme therapy can lead to more serious health problems down the road. These potential complications include progressive malnutrition, severe weight loss, and deficiencies in fat-soluble vitamins (A, D, E, and K), which can have wide-ranging impacts on overall health [1]. Over time, persistent malabsorption can lead to debilitating symptoms and a lower quality of life. Consistent, correct use of prescribed PERT is vital for managing the condition and avoiding these complications [1].

The Role of a Dietitian in Pancreatic Enzyme Therapy

Working with a registered dietitian is a critical component of managing pancreatic insufficiency. A dietitian can help tailor a dietary plan that supports your digestive needs, potentially adjusting enzyme dosages based on the fat content of your meals [1]. They can also help monitor for symptoms of malabsorption and address any nutritional deficiencies, ensuring you receive the maximum benefit from your enzyme therapy [1].

Finding the Right Pancreatic Enzyme Dose

Dosage is highly individualized and is determined by a healthcare provider based on the severity of your EPI, your body weight, and the fat content of your meals [1]. The goal is to provide enough enzymes to digest your food without causing side effects from an overdose [1]. Monitoring symptoms and stool consistency is a key part of finding the optimal dose, and adjustments may be needed over time [1]. If side effects like diarrhea or bloating persist, it may be a sign that the dose is either too high or too low, requiring a reevaluation [4].
