What does “e56 300 mg” on a pill typically mean?
An imprint of “E56” is commonly used to identify a specific quetiapine tablet strength and manufacturer, but the imprint text alone usually does not prove the exact product source without also matching the full imprint pattern (including any letters/numbers besides “E56”), the tablet shape/color, and whether the tablet is marked “300” on the same face.
Is “e56 300 mg” the same as Seroquel (quetiapine)?
Yes. Quetiapine tablets are marketed under brand names such as Seroquel, and pills marked with a strength like “300 mg” indicate the drug is quetiapine at that dose. Seroquel products can vary by formulation and manufacturer, which is why the imprint matters.
How to identify the manufacturer more reliably
To pin down the manufacturer for “E56 300 mg,” you generally need:
- The exact imprint as printed (every character and its placement).
- Tablet color.
- Tablet shape (oval, round, etc.).
- Whether the imprint is on one side or both sides.
If you can share the tablet’s color and shape (and the complete imprint exactly as shown), the manufacturer identification becomes much more accurate.
Can “E56” map to multiple manufacturers or formulations?
Sometimes. Imprints can overlap across manufacturers or across different quetiapine generic/formulation types (immediate-release vs. extended-release). Matching the complete imprint and tablet appearance is the standard way to avoid misidentifying the source.
Safety note if you’re checking a pill at home
If you’re unsure about a pill’s identity, don’t rely only on a partial imprint. Consider:
- Asking a pharmacist to identify it using the National Drug Code (NDC) and imprint data.
- Checking that the tablet’s appearance matches your prescription bottle’s label and form (IR vs XR).
If you want, I can help narrow it down
Reply with:
1) tablet color, 2) tablet shape, 3) whether “E56” and “300” are on the same side, and 4) any other markings visible.
With that, I can tell you which quetiapine product the imprint most closely matches and the manufacturer associated with it.
