Virtually every filler, in every medication, mapped.
AllergenMaps reads FDA-listed drug labels and maps the inactive ingredients to the allergens, diets, and religious needs that matter at the point of care.
How we categorize
One excipient, three tiers.
Every flag carries one of three risk tiers, so the signal is honest about its certainty.
Confirmed Risk
The filler is documented in the product’s own labeling. The risk is on the label.
Sourcing-Dependent
The risk depends on the manufacturer’s source. Flagged for verification with the manufacturer.
Cross-Contamination Risk
Not in the formula itself, but facility-level exposure is possible.
From label to answer
We read every label
550K+ FDA-listed medications, active and discontinued, kept current.
We normalize the fillers
Thousands of ingredient naming variants resolve to roughly 4K unique fillers, so the same excipient reads the same on every label.
We map and clinically review
Each filler is mapped to 100+ allergen, dietary, and religious categories, and the mapping is clinically reviewed before it ships.
Built on official FDA and NLM data.
What we screen for
100+ allergen, dietary, and religious categories across allergy, diet, and faith. The most common:

Common questions
Questions, answered
Where does the data come from?
Official FDA and NLM data. Which datasets we combine, and how, is part of our core work and stays in-house.
How current is the data?
The database refreshes on a weekly to monthly cycle, and formulation changes land on the exact product (the NDC), not just the drug name.
How is the allergen mapping built?
Every filler is mapped to allergen, dietary, and religious categories, and each mapping is clinically reviewed before it ships. The mapping itself is our core work and stays in-house.
Do you cover discontinued and repackaged products?
Yes. Active and discontinued products are both indexed, and repackaged products inherit the formulation of the original manufacturer.
Does patient data touch the platform?
No. Lookups are by product, not by patient, and no PHI is collected or required.
I’m a patient or caregiver, not a professional. Is there a tool for me?
Yes. AllergenMeds is our app for patients and caregivers: look up any medication and see what’s inside. Explore AllergenMeds
