HelloPharmacist Scorecard of Lacto Digest by Highland Laboratories
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
Lacto Digest contains six active ingredients: papain (an enzyme from papaya), bromelain (an enzyme from pineapple), lactase (an enzyme that breaks down milk sugar), pancreatin (a digestive enzyme blend from pork pancreas), rennin (an enzyme used in cheese-making), and Lactobacillus acidophilus (a live probiotic bacteria). Together they're designed to support digestion of food and lactose.
The capsule also contains inactive ingredients — calcium phosphate, gelatin, cellulose, silica, and magnesium stearate — which serve as fillers and binders.
Does it work?
Strong evidence
The evidence for papain and bromelain across various conditions — from cancer to muscle soreness — is insufficient; we simply don't have reliable data showing they work for those uses. Lactase, however, is rated effective for lactose intolerance and does what it's designed to do: help you digest milk sugar.
Lactobacillus acidophilus has possibly effective evidence for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis, though the strength of that evidence is modest.
How safe is it?
Well-documented data
Papain and bromelain are generally well tolerated short-term at normal doses, though both can trigger allergic reactions — itching, hives, rash, abdominal cramps, diarrhea — in sensitive people. High doses of papain may cause serious stomach or esophageal damage.
Papain is rated possibly unsafe in pregnancy due to safety concerns and should be avoided; bromelain also should be avoided during pregnancy, and safety during breastfeeding is unknown. Lactase is rated likely safe in pregnancy.
Lactobacillus acidophilus is rated possibly safe in pregnancy. Bromelain may cause diarrhea, gas, or stomach upset.
Lactobacillus may rarely cause mild gastrointestinal discomfort, bloating, or flatulence, though these effects are uncommon.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking Lacto Digest if you take warfarin or any blood thinner or antiplatelet drug — papain and bromelain may increase bleeding risk (Moderate severity). If you're on tetracycline antibiotics, the interaction is minor but worth confirming.
If you're taking any antibiotic at all, separate the timing: antibiotics can kill the live probiotic organisms in this product, so space them several hours apart and ask your pharmacist for the best schedule.
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.
Lacto Digest is mostly used for lactose intolerance, where lactase has solid evidence. If you take warfarin or any blood thinner, or if you're on antibiotics, check with your own doctor or pharmacist before starting this product — the interactions here matter.
Pregnant or breastfeeding women should also discuss it with their healthcare provider first, since papain and bromelain safety data are limited or unfavorable.

Lacto Digest by Highland Laboratories Drug Interactions
HelloPharmacist Interaction Report
Lacto Digest by Highland Laboratories contains several ingredients with documented interactions with medications.
The most serious concern is papain's potential to increase the effects of warfarin (a blood thinner), rated Moderate severity — one case report described a patient whose warfarin levels became dangerously high after taking a papain-containing supplement. Bromelain may also boost the antiplatelet effects of blood thinners and blood-thinning drugs, raising bleeding risk.
Lactobacillus acidophilus may theoretically decrease antibiotic effectiveness because antibiotics can kill the live organisms in probiotic supplements.
Read the full breakdown — every affected drug type, severity by severity
Bromelain carries a Minor interaction with tetracycline antibiotics, though study evidence on whether this matters in practice is mixed. Altogether, these interactions span 306 individual medications.
Lactase, pancreatin, and rennin — three of the six ingredients — were not checked or hold no interaction data in our records. Run your exact medications through the search tool on this page to see if any of them are affected.

For each ingredient in Lacto Digest 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.
Acidophilus lactobacillus
Antibiotic Drugs
Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.
Bromelain
Anticoagulant/Antiplatelet Drugs
Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.
Tetracycline Antibiotics
Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.
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.
