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. The link to the DailyMed official drug label is included with each drug search for you to easily access.

🏷️ Label-Based Verification

We use automated scraping technology to scan full drug label images. If a label or official drug 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 providing incomplete or misleading results.

💡 Transparent Results

We clearly display whether a result is based on official labeling, ingredient analysis, or missing data—so you always know what you're seeing.

⚗️ 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 medications inactive ingredients section.
🚫 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.
