What does “E 56” mean on an imprint for 300 mg quetiapine?
On prescription tablets, the imprint code (like “E 56”) is used to identify the specific product—typically the manufacturer or labeler and the tablet’s strength. With only “E 56” and “quetiapine 300 mg,” you can match the tablet to the drug listing for that imprint/strength combination in the FDA’s imprint database or reputable labeler databases.
Which companies make quetiapine 300 mg tablets with imprint “E 56”?
To name the exact manufacturers tied to imprint “E 56” for quetiapine 300 mg, I need one more detail: the country or a photo of the tablet imprints (front and back). Different regions can use different labelers, and the same strength (300 mg) can exist across multiple manufacturers with different imprint codes.
If you share:
- the full imprint text (exact characters), including any letters/numbers besides “E 56,” and
- whether there’s any other imprint on the same tablet (or the back imprint),
I can narrow it to the correct manufacturer(s).
How to quickly find the manufacturer yourself (fastest path)
You can confirm the labeler/manufacturer linked to “E 56” + 300 mg by checking the FDA imprint database using the imprint code exactly as it appears on your tablet. This will list the “labeler” for that specific imprint/strength match.
If you’re asking for substitution at the pharmacy
Quetiapine is typically available from multiple generic manufacturers. If you’re trying to ensure you get the same manufacturer as a previous prescription, the pharmacy will usually be able to check the NDC/labeler on the prescription fill. The imprint code is helpful, but NDC is what the pharmacy dispenses.
