Inactive ingredients by manufacturer

Metformin / Sitagliptin inactive ingredients by manufacturer

Wondering whether your Metformin / Sitagliptin 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 Metformin / Sitagliptin 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 37 of the 37 current Metformin / Sitagliptin products on the market today, from 9 companies listing it with the FDA, and lined them up side by side.

Dr. Brian Staiger, PharmD, BCPS
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 Metformin / Sitagliptin inactive ingredients

Is Metformin / Sitagliptin gluten-free?
This page cannot certify any Metformin / Sitagliptin product gluten-free; it reports what each label declares. Of the 37 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 Metformin / Sitagliptin contain lactose?
No checked Metformin / Sitagliptin product lists lactose on its label. 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 Metformin / Sitagliptin contain soy?
No checked Metformin / Sitagliptin 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 Metformin / Sitagliptin?
19 of 37 checked Metformin / Sitagliptin products list a synthetic dye (an FD&C or D&C colorant); 18 do not: A-S Medication Solutions (SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 500 mg tablet and SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 1000 mg tablet), Apotex (SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 500 mg tablet and SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 1000 mg tablet), Golden State Medical Supply (SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 500 mg tablet and SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 1000 mg tablet) and Merck Sharp & Dohme (SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 500 mg tablet and SITAGLIPTIN PHOSPHATE 50 mg/1; METFORMIN HYDROCHLORIDE 1000 mg tablet) and 4 other companies. Colorants often differ by strength within one company's line, so compare the lists above strength by strength.
Does Metformin / Sitagliptin contain gelatin?
No checked Metformin / Sitagliptin 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 Metformin / Sitagliptin 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 Metformin / Sitagliptin 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.
