HelloPharmacist Scorecard of DuoZyme by Karuna
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Partial disclosure
DuoZyme is a blend of 9 digestive enzymes designed to help break down food. It contains amylase (for carbohydrates), papain (a protein-digesting enzyme from papaya), protease and pepsin (additional protein breakers), lipase (for fats), pancreatin (a mix of multiple enzymes from pancreas), and betaine HCl and glutamic acid hydrochloride (to support stomach acid).
It also includes ox bile extract to aid fat digestion. The inactive ingredients are silica, vegetable stearate, stearate, and maltodextrin — these are fillers and binders that make up the capsule.
Does it work?
Strong evidence
The evidence for most ingredients in DuoZyme is not established in our data. Pancreatin is rated as effective for pancreatic insufficiency — a condition where the pancreas doesn't produce enough digestive enzymes.
For the other ingredients and conditions (papain for muscle soreness or shingles, lipase for digestive upset, betaine HCl for indigestion or hay fever, and protease for general digestion), the evidence is insufficient to rate them reliably. That doesn't mean they don't work — it means we don't have strong studies to confirm it.
How safe is it?
Well-documented data
Papain is generally well tolerated when taken at normal doses short-term, though allergic reactions can occur in sensitive people — symptoms include itchy eyes, runny nose, sneezing, abdominal cramps, and diarrhea. At high doses, it may rarely cause severe stomach inflammation or even esophageal perforation.
Pancreatin and the other enzymes are generally well tolerated but may cause mild digestive upset, constipation, diarrhea, or allergic reactions in some people. Betaine HCl can irritate the stomach and shouldn't be used if you have ulcers, gastritis, or true acid reflux.
Pregnancy and breastfeeding: papain is possibly unsafe in pregnancy, especially concentrated forms or unripe papaya products — avoid it. Betaine HCl should be avoided in both pregnancy and breastfeeding due to insufficient safety data.
For protease, pepsin, pancreatin, and lipase, there isn't enough safety data for pregnancy and breastfeeding — talk with your doctor or pharmacist before using if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking DuoZyme if you're on warfarin (Coumadin) — papain may increase its effects. Also flag acarbose (Precose) for diabetes, as pancreatin may reduce how well it works.
If you take antacids, H2-blockers like famotidine, or proton pump inhibitors (PPIs like omeprazole), betaine HCl could make them less effective. Run your complete medication list through the interaction checker on this page.
The bottom line
Scorecard at a glancePartially disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
DuoZyme is designed to help digest food if you have trouble with pancreatic enzymes or need digestive support, but it's not right for everyone. If you take warfarin, acarbose, antacids, H2-blockers, or PPIs, or if you have ulcers or acid reflux, check with your doctor or pharmacist before starting it.
Same goes if you're pregnant, breastfeeding, or have a serious digestive condition — get personalized advice from your healthcare provider first.

General Statements
Fatty acids and botanicals for fungal control
Fast-acting, full range digestive enzymes
Responsible nutrition
DuoZyme utilizes the technologically superior enzyme-release system which was favorably evaluated by Dr. David Graham in an entric-coated pancreatic enzyme preparation that works (dig Dis Sci 1979;24:906-9).
FDA Statement of Identity
Dietary Supplement
Formula
Proper digestion requires both a gastric phase supplying hydrochloric acid and pepsin, and an alkaline duodenal phase supplying protease, amylase, and lipase enzymes. Duozyme provides all of these factors in a single, convenient, high potency capsule delivery system.
DuoZyme contains the acidulants betaine HCl and glutamic HCl, which help acidify gastric contents, creating a favorable environment for the proteolytic action of pepsin. Pancreatin and ox bile extract, contained in pH-sensitive microspheres, supplement the natural secretions of the pancreas and liver, and promote the intestinal phase of digestion. pH-sensitive microspheres typically provide a more effective means for delivering intact enzymes to the small intestine to reduce malabsorption of macronutrients (Dig Dis Sci 1979;24:906-9).
Suggested/Recommended/Usage/Directions
Suggested use for adults: Two or more capsules, taken with meals, or as directed.
Precautions
Warning: Patients with active peptic ulcer should use HCl product with caution.

DuoZyme by Karuna Drug Interactions
HelloPharmacist Interaction Report
DuoZyme by Karuna contains several digestive enzymes, and through its papain and pancreatin content, it does interact with medications.
The most serious interaction is between papain and warfarin (Coumadin), a blood thinner — papain may increase warfarin's effects and side effects, potentially raising your bleeding risk. One patient on stable warfarin developed dangerously high blood thinning (an INR of 7.4) after taking a supplement containing papain.
Read the full breakdown — every affected drug type, severity by severity
Betaine HCl in this product interacts with three types of acid-reducing drugs — H2-blockers (like famotidine), antacids, and proton pump inhibitors (PPIs) — though these are minor interactions. Because betaine HCl increases stomach acid and these medications work to decrease it, they may work less well if taken together.
Pancreatin, another ingredient here, may reduce the effect of acarbose (Precose), a diabetes medication. The enzymes in pancreatic products can break down acarbose, making it less effective.
Altogether, these interactions span 39 individual medications.
We could not check amylase, glutamic acid hydrochloride, or ox bile extract for interactions — we hold no data for those. To confirm whether your specific medications are affected, use the interaction checker on this page with your exact drug names.

For each ingredient in DuoZyme with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Betaine HCl
Antacids
Betaine hydrochloride increases stomach acidity and could decrease the effects of antacids.
In human research, betaine hydrochloride increases stomach acidity. Antacids are taken to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with antacids might decrease the effects of the antacids.
H2-Blockers
Betaine hydrochloride increases stomach acidity and could decrease the effects of H2-blockers.
In human research, betaine hydrochloride increases stomach acidity. H2-blockers are used to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with H2-blockers might decrease the effects of H2-blockers.
Proton Pump Inhibitors (Ppis)
Betaine hydrochloride increases stomach acidity and could decrease the effects of PPIs.
In human research, betaine hydrochloride increases stomach acidity. PPIs are used to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with PPIs might decrease the effects of PPIs
Papain
Warfarin (Coumadin)
Theoretically, papain might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.
Pancreatin
Acarbose (Precose, Prandase)
Theoretically, pancreatic enzyme products may reduce the effects of acarbose.
The digestive enzymes present in pancreatic enzyme products may break down acarbose, reducing its effects.
