I can’t determine the exact manufacturer or “E56” pill identity from your details alone because “E56” (and even “300 mg”) is not a universal, reliable identifier across all imprints and markets. To identify the pill accurately, I need a bit more from you.
What details do you need to identify the quetiapine 300 mg “E56” pill?
Look at the tablet and tell me:
- The exact imprint text (both letters/numbers and any divider lines), including whether it’s “E56” only or something like “E 56,” “E56,” “300,” etc.
- The tablet shape (oval, round, capsule-shaped)
- Color (white, yellow, peach, blue, etc.)
- Any other marking on the other side (for example, “V” or a second imprint)
- Country where you bought it (imprints can differ by manufacturer/region)
With that, I can match it to the correct published tablet identifier more reliably.
How to check the manufacturer on a quetiapine tablet (fastest method)
If the pill label or bottle is available, the manufacturer is usually on:
- the pharmacy label (often includes manufacturer or “generic by” info), or
- the package insert/box (manufacturer name, NDC number).
If you can share the bottle’s NDC number (the 10- or 11-digit number), it can be matched directly.
Is “E56” definitely quetiapine 300 mg?
“E56” could refer to different drug products depending on imprint conventions and country. Because imprints are tied to specific manufacturers and formulations, the same imprint pattern can be associated with different strengths or even different medicines in some listings—so it’s important not to assume the pill is quetiapine without matching the full imprint plus shape/color.
Safety note if you’re unsure
If the tablet’s appearance doesn’t match what you normally take, don’t guess. Confirm using the full imprint plus color/shape, or ask your pharmacist to verify using the NDC.
If you reply with the imprint, I’ll identify it
Send these details:
1) Exact imprint (front):
2) Other side imprint (if any):
3) Color:
4) Shape:
5) Where you are (country):
6) Is “300 mg” printed on the pill, or is it from the bottle?
Then I can tell you which quetiapine product it matches and the manufacturer associated with that identifier.
