What does an “E56” imprint on quetiapine 300 mg mean?
An imprint of “E56” on a quetiapine 300 mg tablet is a specific tablet identifier used by manufacturers. The imprint code typically points to the labeler/manufacturer that made that pill, but the manufacturer is not always determinable from imprint alone without the product database or the exact package/NDC.
How to find the manufacturer for quetiapine 300 mg with imprint E56
The most reliable way to confirm the manufacturer is to use the tablet’s National Drug Code (NDC) from the bottle (or the image of the bottle label). If you share the NDC, you can match it to the specific listed manufacturer for that exact product.
If you do not have the NDC, the next best step is to cross-check the imprint “E56” and strength “300 mg” in a reputable pill-identifier database that lists manufacturer/labeler by imprint.
Risks of relying on imprint alone
Imprints can be reused across different production runs or related strengths by different labelers. Also, counterfeit or mispackaged tablets can exist. For safety, confirm with the bottle label (NDC/manufacturer) and ask a pharmacist if anything does not match what your prescription expects.
What to do if you’re trying to verify your medication
If you can, check:
- The NDC on your bottle (most definitive)
- The manufacturer name next to “manufactured for” / “labeled by”
- Your pharmacy’s dispensed product (often shown in your pharmacy app/receipt)
If you want, I can identify it precisely
Reply with either:
1) the NDC number from your bottle, or
2) a photo of the imprint plus the side of the tablet that has other markings (if any) and the label text from the bottle.
Then I can tell you the likely manufacturer for that exact quetiapine 300 mg product.
