Which company makes the “E 56” quetiapine 300 mg tablet?
To identify the manufacturer for a specific pill (imprinted with “E 56”) you need the pill’s exact imprint and strength, plus the tablet’s color/shape. The imprint “E 56” alone is not enough for a reliable match because multiple quetiapine products can share similar-looking imprints across manufacturers, countries, or packaging runs.
What details should you check on the bottle to confirm the manufacturer?
Look for any of the following on your prescription label or medication packaging:
- National Drug Code (NDC)
- Manufacturer name (often listed as “made for” or “by”)
- Dosage form details (immediate-release vs extended-release)
- Tablet color and shape
- Imprint text exactly as shown (including spaces or line breaks)
If you can share the tablet’s color/shape and whether it says “IR” (immediate-release) or “XR” (extended-release), I can help you narrow it down to the correct manufacturer.
Is “quetiapine 300 mg” usually immediate-release or extended-release?
Quetiapine tablets come in different formulations. The imprint you see may correspond to either:
- immediate-release quetiapine tablets, or
- extended-release quetiapine tablets (often labeled differently on packaging).
The manufacturer and imprint mapping can differ by formulation, so the bottle label is the fastest way to confirm.
If you want, I can identify it—send these two items
1) Tablet appearance: color + shape (e.g., “white, oval, scored”)
2) The imprint exactly: is it “E 56” or “E56” (with any spacing), and is there any other marking?
