Always consult your pharmacist or physician before taking any new medication if you have celiac disease or gluten sensitivity. Formulations can change without notice.
Allegra (fexofenadine), including the standard Sanofi-manufactured tablets, is considered gluten-free. This matters because many of us following a strict gluten-free lifestyle due to celiac disease or gluten sensitivity worry about hidden gluten in medications. I get asked about Allegra all the time, especially since my son takes allergy meds regularly. For quick checks on other foods or meds, check out our gluten-free food checker.
The Short Answer
Standard Allegra tablets and Allegra-D tablets made by Sanofi do not contain gluten. They have no gluten-containing inactive ingredients and are considered safe for people with celiac disease. Generic fexofenadine products may vary, so always verify with your pharmacist before starting any new medication.
What Makes Allegra (Fexofenadine) Gluten-Free?
The primary ingredient in Allegra is fexofenadine hydrochloride, an antihistamine that helps control allergy symptoms like sneezing, runny nose, and itchy eyes. The key question is whether any of the inactive ingredients contain gluten or if cross-contamination is possible during manufacturing.
Sanofi, the maker of Allegra, confirms that their standard and Allegra-D formulations do not include gluten-containing ingredients. That means no wheat, barley, rye, or their derivatives in the ingredient list. The inactive ingredients typically include things like microcrystalline cellulose, magnesium stearate, and various dyes — all gluten-free and commonly used in many medications.
Since Allegra is a medication rather than a food product, the FDA does not require gluten labeling. That’s why it’s important to check with the manufacturer or your pharmacist if you have any doubts.

Allegra Products/Varieties to Watch Out For
While the Sanofi versions of Allegra and Allegra-D are gluten-free, generic fexofenadine products can differ. Some generics may contain fillers or excipients derived from gluten-containing sources or may be produced in facilities where cross-contact is possible. For example, a generic might use wheat starch as a binder, which could trigger symptoms in sensitive individuals.
Always double-check the inactive ingredients on any generic packaging and confirm with your pharmacist. If you’re unsure, stick with the brand-name Sanofi Allegra, which has a clear gluten-free status and a strong track record of safety.
| Product | Manufacturer | Gluten Status | Notes |
|---|---|---|---|
| Allegra 24hr Tablets | Sanofi | Gluten-Free | Standard formula, no gluten-containing ingredients |
| Allegra-D (12hr) | Sanofi | Gluten-Free | Includes pseudoephedrine, but no gluten |
| Generic Fexofenadine | Various | Varies | Check labels and verify with pharmacist |
Safe Gluten-Free Allegra Options
When it comes to allergy medications, sticking with trusted brands can reduce the risk of gluten exposure. Here are my top picks for gluten-free Allegra options:
- Allegra 24hr tablets by Sanofi: Widely available at pharmacies like CVS and Walgreens, and known for consistent gluten-free formulations.
- Allegra-D 12hr tablets by Sanofi: For allergy relief plus nasal decongestant, also gluten-free and suitable for those who need extra congestion control.
- Consult your pharmacist for verified generic options: Some generics may be gluten-free, but always confirm before switching products.
Remember, always read ingredient labels carefully, and when in doubt, call the manufacturer or your pharmacist for the most current information.
How to Read Medication Labels for Gluten
Medications don’t have to list gluten explicitly, so look out for hidden sources. Here’s what to watch for:
- Inactive ingredients: Look for wheat starch, barley malt, or any grain derivatives. For example, some capsules use wheat starch as a filler, which is a red flag.
- Cross-contact warnings: Some labels mention if produced in shared facilities where gluten-containing products are processed.
- Check manufacturer websites: Many provide gluten-free statements online, often in the FAQ or product information sections.
- Ask your pharmacist: They can often provide up-to-date info on generics and may have access to manufacturer data not printed on the label.

Tips for Shopping Gluten-Free Allergy Medications
Shopping for allergy medications while avoiding gluten can feel tricky, but a few practical strategies help me every time:
- Stick to brand-name products when possible: Sanofi’s Allegra lines have reliable gluten-free status, reducing guesswork.
- Keep a list of safe products handy: Whether on your phone or a printed note, having your trusted meds listed saves stress at the pharmacy.
- Use your pharmacist as a resource: Don’t hesitate to ask them to check the latest ingredient info or call manufacturers for you.
- Watch for changes in packaging or formulation: Sometimes manufacturers switch suppliers or ingredients without much notice, so double-check periodically.

Being proactive and organized makes managing allergies and celiac disease a lot easier, especially during busy allergy seasons.

Yes, even small amounts of gluten from medications can trigger symptoms in sensitive individuals with celiac disease or gluten sensitivity. These symptoms might include digestive upset, fatigue, skin rashes, or headaches. That’s why vigilance with medications is just as important as with food.
Are liquid allergy medications safer for gluten-free diets?
Liquid medications can sometimes be safer because they often use different inactive ingredients than tablets. However, some syrups may contain gluten-containing thickeners or flavorings. Always check the ingredients and consult your pharmacist before switching forms.
When my son was first diagnosed with celiac disease, I was overwhelmed with questions about his medications.
