What does “E56 imprint” mean on quetiapine tablets?
“E56” is an imprint code used on some quetiapine tablets to identify the specific product. Imprint codes typically correspond to a particular manufacturer and tablet strength/formulation.
Which other manufacturers make quetiapine with an E56 imprint?
The provided information doesn’t include a mapping between the “E56” imprint and the full list of quetiapine manufacturers that use that same imprint. Because imprints are product- and strength-specific, the manufacturer can also vary by tablet strength (e.g., 25 mg vs 100 mg vs 300 mg) and by immediate-release vs extended-release formulations.
How to find the manufacturer tied to your specific “E56” quetiapine
Check these details on the bottle or blister:
- The quetiapine strength (mg) and whether it is immediate-release or extended-release
- The National Drug Code (NDC) listed on the label
- The image or details of the imprint (E56) on the tablet itself
With the NDC, you can identify the exact manufacturer reliably. If you share the strength (and whether it’s IR or XR), plus the NDC from the package, I can help narrow down the manufacturer(s).
Can E56 be shared across generics from multiple companies?
Yes. In some cases, more than one company may market a product that ends up with the same imprint code, especially when different labeled products use similar tablet configurations. That said, the safest way to confirm the “other manufacturers” for your tablet is to use the NDC, because imprints alone don’t always uniquely identify every branded/generic source across strengths and formulations.
Quick next step
Reply with:
1) Quetiapine strength (mg)
2) IR or XR (if you see “XR” or “ER” on the label, include it)
3) The NDC number from the bottle
Then I’ll list the manufacturer(s) associated with that exact product and identify other companies tied to the same strength/form.
