E 56 pill quetiapine manufacturer?

What “E 56” means on a quetiapine tablet

“E 56” is an imprint code used to identify a specific tablet. Imprints vary by manufacturer and country, so the same imprint can correspond to different products depending on where the pill is sold.

How to find the exact quetiapine manufacturer for “E 56”

To identify the manufacturer reliably, you typically need:
- The exact imprint as printed (including any letters/numbers spacing), and whether it’s also marked on the other side
- The tablet strength (for example, 25 mg, 50 mg, 100 mg, 200 mg)
- The pill color and shape
- Your country (manufacturer lists differ by region)

Without the strength/color/shape or a second imprint, it isn’t possible to pinpoint the manufacturer with certainty.

If you’re trying to confirm safety for a specific prescription

If this pill is in your possession and you’re unsure it matches your prescription, don’t guess from imprint alone. You can:
- Check the prescription label/pharmacy packaging for the strength and manufacturer
- Use your pharmacy to confirm which product matches imprint “E 56”

If you share the pill’s color/shape and the strength (or a photo description of both sides of the imprint), I can help narrow down which quetiapine product “E 56” corresponds to.
