What does “E 56” mean on quetiapine packaging?
“E 56” is an imprint code, not the manufacturer name. Imprints are used to identify a specific solid-dose product/strength, and the company tied to that imprint depends on the exact tablet strength and the way the product is labeled.
How can I find the quetiapine manufacturer for imprint “E 56”?
To identify the manufacturer for quetiapine marked with imprint “E 56,” you typically need the other identifying details from the same tablet, especially:
- The quetiapine strength (e.g., 25 mg, 100 mg, 200 mg, etc.)
- The dosage form (immediate-release vs extended-release)
- The tablet shape/color
- Any other letters/numbers on the tablet (imprint can include more than one character)
If you share those details (photo or the exact text around the imprint), I can narrow down which labeler/manufacturer matches “E 56.”
Why the same imprint may be associated with different companies
Multiple manufacturers can make generic quetiapine tablets, and imprints can be used differently across labels. Also, relabeling or product changes (strength/formulation) can cause imprint/manufacturer mismatches if only one imprint is provided.
Quick next step
Reply with the quetiapine tablet strength and whether it’s immediate-release or extended-release (or upload the imprint text exactly as shown). Then I can pinpoint the manufacturer associated with imprint “E 56.”
