E56 pill quetiapine 300 mg manufacturer?

Which company makes the E56 pill (quetiapine 300 mg)?

I don’t have enough information to identify the manufacturer for an “E56” imprint on a quetiapine 300 mg tablet from the details provided. Pill imprints can vary by country/state and are sometimes reused across different manufacturers.

What I need to pin down the exact manufacturer

If you share any of the following, I can narrow it to the right product/manufacturer:
- A photo of the tablet imprint (both sides, if possible)
- The exact imprint as printed (e.g., E56 on one side, and what’s on the other side)
- Whether it’s an immediate-release or extended-release tablet (if shown on the packaging)
- Your country (US, Canada, UK, etc.)

How you can quickly confirm the maker yourself

You can look up the imprint in a reliable pill database that lists manufacturer/distributor when available. If you want, paste the results you see (or the link), and I’ll help interpret them.
