Inactive ingredients by manufacturer

Thioridazine inactive ingredients by manufacturer

Wondering whether your Thioridazine 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 Thioridazine 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 11 of the 20 current Thioridazine products on the market today, from 5 companies listing it with the FDA, and lined them up side by side. 5 are still being read and will appear on a later visit. 4 labels have no inactive-ingredient list we could read, so those products cannot be compared.

Ask about your bottle

Is there something in your Thioridazine? Ask in plain words.

Name the company, strength or the NDC on your bottle and the ingredient you avoid. The answer comes only from the FDA labels on this page.

Answers are drawn from the FDA label data on this page and checked against it. They are not medical advice: confirm with your pharmacist before relying on them.

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 Thioridazine inactive ingredients

Is Thioridazine gluten-free?
This page cannot certify any Thioridazine product gluten-free; it reports what each label declares. Of the 11 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 Thioridazine contain lactose?
2 of 11 checked Thioridazine products list lactose; 9 do not: Mylan (10 mg tablet, 25 mg tablet and 50 mg tablet and 1 more), Mylan Institutional (25 mg tablet and 100 mg tablet) and Safecor Health (10 mg tablet, 25 mg tablet and 100 mg 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 Thioridazine contain soy?
No checked Thioridazine 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 Thioridazine?
Every checked Thioridazine product (11) 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 Thioridazine contain gelatin?
No checked Thioridazine 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 Thioridazine 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 September 24, 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.

Sources: the products are the finished Thioridazine products in the FDA's current NDC directory (openFDA), as of September 24, 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.
