Inactive Ingredient Finder

Same medicine. Different fillers. Find the version that leaves out what you avoid.

Lactose, gluten sources, soy, dyes, gelatin. Every current product of a medicine, every company, straight from the FDA label, with the NDC to ask your pharmacy for.

1,056 medicines so far, browse the full directory. Rebuilt daily from the FDA's NDC directory.

Why the company matters

The active ingredient is the same in every version of a generic. The fillers, coatings and colors are not. One company's tablet lists lactose, the next one's lists none. This tool reads the label of every current product so you can see which is which.

Check your bottle

Type the NDC from the pharmacy label, the company and strength, or tap your way: form, strength, company. Any pack size of a product finds it.

Ask in plain words

"Does the Teva 10 mg have gelatin?" The answer comes only from the page's own label data, names the product and its NDC, and suggests the next question.

How it works

No account, no upload, nothing to install. The page is built from public FDA data and does its checking on the page.

Find your medicine

Type its name above or pick it from the directory. Each medicine has one page that compares every current product of it.

Pick your bottle

The NDC on the pharmacy label is fastest (call your pharmacy if it is not printed). Or choose the form, the strength and the company.

Read the label, take the NDC

See what that product lists, what it does not, and where a source is not stated. Copy a note for your pharmacist and ask for the version you want by its NDC.

What it does, and what it does not

  • It shows the manufacturer's own FDA label, word for word. Nothing is added or taken away.
  • "Not listed" means the label does not name an ingredient. It never means "free of": a starch, flavor or maltodextrin can have an unstated source, and the page says "source unclear" when that is so.
  • It never tells you to take, stop or avoid a medicine. It gives you the facts to bring to your pharmacist or prescriber.
  • Formulations change. Check the label on the bottle you are handed, and ask if a refill looks different.

Questions people ask

What is the Inactive Ingredient Finder?

A free tool that compares every current product of a medicine, company by company, using the inactive-ingredient list on each FDA label. It shows which versions list lactose, a gluten source, soy, synthetic dyes or gelatin and which do not, and gives you the NDC to ask your pharmacy for.

Where do the ingredient lists come from?

From the manufacturers' own FDA labels (the structured product labeling on DailyMed), as our label sync last read them. The product list is the FDA's current NDC directory, rebuilt daily. Nothing is added to or removed from a label; the classification of which names count as a lactose, gluten, soy, dye or gelatin source is written and maintained by Dr. Brian Staiger, PharmD, BCPS.

Does "not listed" mean "free of"?

No. It means the label does not name the ingredient. A starch, a flavor or a maltodextrin can have an unstated source, and the pages say "source unclear" when that is the case. Only the manufacturer can confirm a source; the page tells you when to ask them.

Which medicines are covered?

Every medicine in the directory on this page: a page is listed once at least one label has been read and there are two companies to compare. The list grows as labels are read.
