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 Pyrazinamide inactive ingredients

Is Pyrazinamide gluten-free?
This page cannot certify any Pyrazinamide product gluten-free; it reports what each label declares. Of the 4 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 Pyrazinamide contain lactose?
No checked Pyrazinamide 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 Pyrazinamide contain soy?
No checked Pyrazinamide 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 Pyrazinamide?
No checked Pyrazinamide 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 Pyrazinamide contain gelatin?
No checked Pyrazinamide 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 Pyrazinamide 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 5, 2026, and each inactive-ingredient list is the manufacturer's FDA label as our label sync last read it. Formulations change, so check the label on your own bottle and ask your pharmacist if a refill looks different.
