Aler-Gest Ingredients & Drug Interactions
What is this page for?
First and foremost: checking Aler-Gest against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Aler-Gest by Douglas 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
Full disclosure
Aler-Gest contains three active digestive enzymes. Lipase breaks down dietary fats, protease breaks down proteins, and amylase breaks down starches — together they're meant to support digestion.
The tablet also contains several inactive ingredients including sorbitol, cellulose, vegetable stearate, silica, alfalfa powder, natural peppermint flavor, and date powder.
Does it work?
Not established
The evidence for these enzymes is limited. Lipase and protease have been studied for inflammatory bowel disease (IBD) and dyspepsia (indigestion), but the data we hold is marked insufficient to rate their usefulness for those conditions.
Amylase's effectiveness ratings are not on file. If you're considering this product for a specific digestive issue, talk it over with your doctor or pharmacist — they can help you weigh whether enzyme supplements make sense for your situation.
How safe is it?
Well-documented data
Lipase and protease are generally well tolerated in adults, though protease may occasionally cause digestive upset or allergic reactions. There's little safety data on either ingredient during pregnancy or breastfeeding — if you're pregnant or nursing, talk with your doctor or pharmacist before taking this product.
One caution: recombinant human bile salt-stimulated lipase (a specific form used in premature infants) has caused serious gastrointestinal problems in that population, so this product is not for use in infants.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, we don't hold interaction data for amylase, so run your full medication list through the search tool on this page to be safe.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Aler-Gest is a basic digestive enzyme blend. If you have a normal stomach and want to try digestive support, the enzymes we checked show no known medication interactions and are generally well tolerated.
If you have a serious digestive condition, are pregnant or breastfeeding, or take any medications, check with your doctor or pharmacist first.
