Same active ingredient, same strength, same dosage form.

That is the whole claim. Salvio compared the FDA-filed active ingredient, its strength and the dosage form — nothing else. It does not mean these products are medically interchangeable for you. Inactive ingredients, coatings and release behaviour differ between them and are listed per product below. Ask a pharmacist before switching.

Because these are the same drug, taking two of them is a double dose

25 of 55

28 of these 55 products have no inactive-ingredient list on file

The FDA label was never published for those NDCs. Salvio shows the gap rather than filling it. An empty inactive-ingredient list is not evidence that a product is free of any allergen — it is evidence that nobody filed the data.
