🆚 What’s the Difference Between These Two NDCs?

Got two versions of the same medicine and want to know how they really compare? Drop in both NDC numbers and we’ll put them side by side — who makes each one, what the pill looks like, the inactive ingredients inside, gluten and allergen flags read straight off the FDA label, and what pharmacies actually pay.

VS

You’ll find the NDC on the bottle, the box, or your pharmacy label — or look one up with our NDC Lookup.

Allergen & sensitivity flags we look for
Major food allergens We scan for wheat, milk protein, egg, fish, crustacean shellfish, FDA-listed tree nuts, peanut, soy, and sesame.
Other things people react to Lactose, sulfites, named FD&C colors, alcohol/ethanol, aspartame/phenylalanine, and gelatin or lecithin when the source isn’t spelled out.

We only go by what the FDA label actually says — the exact-product ingredient list plus any clear content statement. We don’t guess from pill color or missing text, and this is never a “free-from” claim. Drug labels also aren’t held to the food-allergen labeling rules, so always confirm a serious allergy with your pharmacist.
