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 Donepezil / Memantine inactive ingredients

Is Donepezil / Memantine gluten-free?
This page cannot certify any Donepezil / Memantine product gluten-free; it reports what each label declares. Of the 14 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 Donepezil / Memantine contain lactose?
8 of 14 checked Donepezil / Memantine products list lactose; 6 do not: Amneal (MEMANTINE HYDROCHLORIDE 7 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule, MEMANTINE HYDROCHLORIDE 14 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule and MEMANTINE HYDROCHLORIDE 21 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule and 1 more), ANI (MEMANTINE HYDROCHLORIDE 21 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule) and AvKARE (MEMANTINE HYDROCHLORIDE 28 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule). 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 Donepezil / Memantine contain soy?
No checked Donepezil / Memantine 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 Donepezil / Memantine?
10 of 14 checked Donepezil / Memantine products list a synthetic dye (an FD&C or D&C colorant); 4 do not: ANI (MEMANTINE HYDROCHLORIDE 21 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule), Macleods (MEMANTINE HYDROCHLORIDE 14 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule and MEMANTINE HYDROCHLORIDE 28 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule) and Vitruvias Therapeutics (MEMANTINE HYDROCHLORIDE 14 mg/1; DONEPEZIL HYDROCHLORIDE 10 mg extended-release capsule). Colorants often differ by strength within one company's line, so compare the lists above strength by strength.
Does Donepezil / Memantine contain gelatin?
Every checked Donepezil / Memantine product (14) 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 Donepezil / Memantine product can list lactose and a dye while another from a different company lists neither.
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?
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 Donepezil / Memantine 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 Donepezil / Memantine guide
