Milk Allergens Hiding in Medicine?

Milk Allergens in Medicine: Use RxAllergyScan

Milk allergens in medicine, like lactose, hide in many prescriptions. If you’re sensitive to milk proteins, it’s not just food labels you need to check—many medicines use lactose as an excipient because it compresses well and stabilizes tablets. RxAllergyScan helps you quickly check a medication’s inactive ingredients—including lactose/lactose monohydrate and other milk-related terms—so you can spot issues before taking them.

Why Milk Allergens Appear in Medicine

  • Tablets & capsules: Lactose, a milk allergen, is a common filler to help tablets form and hold together. It’s widely used in oral medicines. U.S. Food and Drug AdministrationPMC

  • Inhalers: Many dry powder inhalers (DPIs) use lactose as a carrier. While lactose is a sugar, trace milk proteins can be present, a risk for those with milk allergies. AAAAI

With RxAllergyScan, you can check if milk allergens in medicine, like lactose monohydrate or whey, are in your prescriptions’ inactive ingredients list.
