A product with none of these on its label may still contain them. The label shows only what the company listed, and it often does not say where a starch or a flavor comes from. Some companies here repackage or sell another company's product under their own name. Tap an NDC to open that product's page with its full label.

At the pharmacy counter

How to Get the Version You Want at the Pharmacy

Pick the company whose list suits you and copy the NDC from the table. Many pharmacies order from wholesalers that carry several companies' versions and can request a particular one if you ask before the prescription is filled; some buy from one contracted source only, and a few insurance plans cover only certain NDCs, so ask the pharmacist to check.
Treat "does not list" as exactly that. The label is what the manufacturer declared; a flavor or a starch may have an unstated source, and lines change. For celiac disease or a serious allergy, ask the manufacturer's medical information line for a written statement about the lot you have.
Check the bottle each refill. A different company usually means a different shape, color and inactive-ingredient list; the pharmacist can tell you who made it, and the two-NDC comparison shows the difference line by line.
If you need one company's version kept constant, ask your prescriber to write that company or the NDC on the prescription and tell the pharmacy you need it held. Rules vary by state and plan, so confirm with the pharmacist.

Common Questions About Fentanyl Inactive Ingredients

Is Fentanyl gluten-free?

This page cannot promise any Fentanyl product has no gluten; it reports what each label declares. Of the 54 products checked, none lists a wheat, barley, rye or gluten ingredient, and none lists a starch or maltodextrin without a stated source. If you have celiac disease, ask the manufacturer's medical information line for a written gluten statement for the lot you have.

Does Fentanyl contain lactose?

No checked Fentanyl product lists lactose on its label. People with a milk allergy or a strong intolerance often prefer a version that does not list it.

Does Fentanyl contain soy?

No checked Fentanyl product lists a soy ingredient (soybean oil or soy lecithin) on its label. Soy lecithin is the usual form and the amount is small, but people with a soy allergy often prefer a version that does not list it.

Is there a dye-free Fentanyl?

No checked Fentanyl product lists a synthetic dye (an FD&C or D&C colorant) on its label. Colorants often differ by strength within one company's line, so compare the lists above strength by strength.

Does Fentanyl contain gelatin?

No checked Fentanyl product lists gelatin on its label. Gelatin is usually bovine or porcine and the label rarely says which; for kosher, halal or vegetarian needs, ask the manufacturer.

Why do the inactive ingredients differ between manufacturers?

A generic must match the brand's active ingredient, strength, dose form and how it is absorbed; its fillers, binders, coatings and colorants are the manufacturer's own choice. That is why one Fentanyl product can list lactose and a dye while another from a different company lists neither.

What can a label not tell me?

A label tells you every inactive ingredient the company names for that product. It cannot tell you where an unnamed flavor, starch or maltodextrin came from, whether traces come from shared equipment, or about a change made after our last read of the label (October 6, 2026). Your pharmacist can check with the manufacturer.

Who decides what counts as a gluten source, a dye or soy on this page?

Dr. Brian Staiger, PharmD, BCPS, a clinical pharmacist, wrote and maintains the classification this page applies: which ingredient names count as a lactose, wheat or gluten, soy, synthetic dye or gelatin source, and which read as "source not stated" (bare starch or maltodextrin). The ingredient lists themselves are the manufacturers' own FDA labels, shown as filed; nothing is added to or removed from a label.

The NDC on my bottle ends differently from the one on this page. Is it the same product?

Usually, yes. An NDC has three parts: the company, the product (the medicine, strength and form) and, last, the package size. Two codes that share the first two parts are the same product in different pack sizes, and a label belongs to the product, so every pack size shares one inactive-ingredient list. Each product on this page lists every pack size the FDA directory holds for it, and the NDC search accepts any of them.

Can my pharmacy give me a specific manufacturer's version?

Often, if you ask before the prescription is filled: many pharmacies order from wholesalers that carry several companies' versions and can request a particular one. Some pharmacies buy a generic from one contracted source only, and a few insurance plans cover only certain NDCs, so ask the pharmacist to check. Give them the NDC from this page; the company name alone is often enough.

How current is this list?

We have read the FDA labels of 54 of the 54 current Fentanyl products on the market today, from 10 companies listing it with the FDA, and lined them up side by side. The products are the ones in the FDA's current NDC directory as of October 6, 2026. The list is rebuilt every day, the FDA directory is re-imported every week, and each inactive-ingredient list is the manufacturer's FDA label as our label sync last read it, re-read when the FDA publishes a new version. Formulations change, so check the label on your own bottle and ask your pharmacist if a refill looks different.

Sources: the products are the finished Fentanyl products in the FDA's current NDC directory (openFDA), as of October 6, 2026; each inactive-ingredient list is the manufacturer's FDA Structured Product Label via DailyMed, as our label sync last read it. The concern groups are HelloPharmacist's classification of the names the label declares. Educational information only, not medical advice; confirm with your pharmacist before relying on a list. ← Back to the Fentanyl guide
