Inactive ingredients by manufacturer

Fesoterodine inactive ingredients by manufacturer

Wondering whether your Fesoterodine has lactose, gluten, soy, a dye or gelatin in it? The medicine is the same, but the fillers, coatings and colors differ from one company to the next. This page shows what each Fesoterodine product's FDA label lists, so you can find a version that leaves out what you avoid and ask your pharmacist for it by its NDC.

We have read the FDA labels of 24 of the 24 current Fesoterodine products on the market today, from 12 companies listing it with the FDA, and lined them up side by side.

Curated and coded by Dr. Brian Staiger, PharmD, BCPS, clinical pharmacist. The ingredient groups this page checks for (what counts as a gluten source, a synthetic dye, soy and so on) are his classification; the lists themselves are the manufacturers' own FDA labels. Updated October 6, 2026. Rebuilt daily from the FDA directory; labels re-read when the FDA publishes a new version.

A product with none of these listed is not certified to be without them: the label says what the manufacturer declared, and the source of a starch or a flavor is often not stated. The companies are the FDA's labelers, which include repackagers and distributors selling another company's product under their own label. The NDC opens the product's own page, with the full label and its inactive-ingredient notes.

At the pharmacy counter

How to use this at the pharmacy counter

  1. 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.
  2. 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.
  3. 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.
  4. 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 Fesoterodine inactive ingredients

Is Fesoterodine gluten-free?
This page cannot certify any Fesoterodine product gluten-free; it reports what each label declares. Of the 24 products checked, none lists a wheat, barley, rye or gluten ingredient, and none lists a starch 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 Fesoterodine contain lactose?
18 of 24 checked Fesoterodine products list lactose; 6 do not: Ascend (4 mg extended-release tablet and 8 mg extended-release tablet), Camber (4 mg extended-release tablet and 8 mg extended-release tablet) and NorthStar RxLLC (4 mg extended-release tablet and 8 mg extended-release tablet). The lactose in a tablet or capsule is a small amount, but people with a milk allergy or a strong intolerance often prefer a version that does not list it.
Does Fesoterodine contain soy?
Every checked Fesoterodine product (24) 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 Fesoterodine?
20 of 24 checked Fesoterodine products list a synthetic dye (an FD&C or D&C colorant); 4 do not: Zydus (4 mg extended-release tablet and 8 mg extended-release tablet) and Zydus Lifesciences (4 mg extended-release tablet and 8 mg extended-release tablet). Colorants often differ by strength within one company's line, so compare the lists above strength by strength.
Does Fesoterodine contain gelatin?
No checked Fesoterodine 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 Fesoterodine product can list lactose and a dye while another from a different company lists neither.
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?
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 Fesoterodine 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 Fesoterodine guide
