E 56 imprint quetiapine 300 mg manufacturer?

What does “E 56” mean on a 300 mg quetiapine imprint?

“E 56” is an imprint code printed on some quetiapine tablets. The imprint helps identify the specific drug product (strength and manufacturer/labeler) when multiple versions are on the market.

To pinpoint the exact manufacturer for “E 56” on a 300 mg quetiapine tablet, you need the full imprint exactly as it appears (including any letters/numbers) and whether it matches other markings like a score line and/or additional text on the other side of the tablet.

If you can share a photo or type the entire imprint from both sides (for example, “E 56” on one side and any numbers/letters on the other side), I can help narrow it to the correct product and labeler.

How to identify the manufacturer yourself (fast)

1. Look for every imprint marking on the tablet (both sides), including any “score” line.
   
2. Note the tablet’s description (color, shape, and whether it is scored).
   
3. Cross-check the imprint in a reliable pill-imprint database (pharmacists and many online databases use imprint+strength+shape to match products).
   
   

Why the manufacturer matters for quetiapine 300 mg

Different manufacturers can use different tablet formulations and packaging, even when the active ingredient and strength are the same. For patients taking quetiapine, switching products can sometimes change the way the tablet dissolves, which can affect tolerability even when the dose is unchanged.

Can you confirm the other side of the tablet?

Reply with:
- Color and shape (e.g., white round scored)
- Any markings on the back side
- Whether “300 mg” is printed anywhere or only implied by your prescription

Then I can help identify which quetiapine 300 mg product corresponds to the “E 56” imprint.
