Quetiapine fumarate 300 mg imprint e 56 manufacturer?

What does “quetiapine fumarate 300 mg” imprint “E 56” mean?

“Quetiapine fumarate” is the active ingredient in the prescription antipsychotic quetiapine. The “300 mg” strength refers to the dose per tablet.

The imprint code “E 56” is used to identify a specific tablet/strength and helps distinguish it from other manufacturers’ versions of quetiapine tablets.

Which manufacturer makes tablets with imprint “E 56”?

You’re asking for the manufacturer tied to the imprint “E 56.” That specific imprint-to-manufacturer mapping is something that must be confirmed against a drug imprint database (the same imprint can sometimes appear across different product lots or labeling systems, depending on how the tablet is distributed).

I don’t have the provided-imprint-to-manufacturer lookup information in the material available here, so I can’t reliably name the manufacturer for “E 56” without checking a dedicated imprint reference.

How to find the manufacturer quickly (safest way)

Check the bottle label or the pharmacy printout. Manufacturer name (or the generic NDC and labeler) is typically shown there, and it’s more reliable than imprint alone.

If you want to identify it by imprint, use a reputable pill-imprint database that lists:
- drug name (quetiapine fumarate)
- strength (300 mg)
- imprint (E 56)
- manufacturer/labeler and/or NDC

If you share the National Drug Code (NDC) from your bottle (usually on the label), I can help you narrow it down.

Why it matters

Quetiapine is dosed carefully, and “look-alike” tablets from different labelers can exist. Confirming the manufacturer/labeler from the bottle or NDC helps prevent mix-ups.

If you paste the exact text from the bottle label (especially the NDC or “manufacturer/labeler” line), I’ll tell you which manufacturer it corresponds to.
