Why AllerGuard Pro?


How Does AllerGuard Determine Gluten Status?

📊 Trusted Source Data

We update our database monthly using official drug information from DailyMed, a government-run site provided by the U.S. National Library of Medicine. Each search includes a link to the official DailyMed drug label for easy access.

🏷️ Label-Based Verification

Automated scraping scans full drug label images. If a label or official insert explicitly states “gluten-free,” the medication is marked gluten-free.

🚫 Missing Data Transparency

If inactive ingredients are missing from official data, we display “Not Available” to avoid incomplete or misleading results.

💡 Transparent Results

We clearly show whether a result is based on official labeling, ingredient analysis, or missing data — so you always know the source of truth.


Ingredient Status Explained

When a medication doesn’t have a clear gluten-free label, AllerGuard analyzes the inactive ingredients to determine risk level:

No Gluten Containing Ingredients

No gluten-containing ingredients are listed in the inactive ingredient section; however, the medication is not explicitly labeled gluten free and does not address cross contamination unless stated.

🚫 Contains Gluten

Known gluten-containing ingredients (like wheat starch) are found in the ingredient list.

⚠️ Caution

Ingredients that might contain gluten (such as “starch” or “modified food starch”) trigger a caution label for user awareness.

Not Available

If inactive ingredients are not provided in official data, the medication is marked as Not Available.

All results are driven by publicly available drug data and automated analysis — ensuring transparent, consistent results without human guesswork.
