What does the “E56” imprint on a 300 mg Seroquel tablet mean?
On prescription tablets, an imprint code like “E56” typically identifies the exact drug product (strength, formulation, and sometimes the maker) used in the country/market where it was packaged. For Seroquel (quetiapine) tablets, “E56” is one such imprint used to distinguish a specific strength/product variant. However, the imprint alone usually isn’t enough to reliably confirm the manufacturer without checking a printed drug-imprint database entry for your exact location.
Who makes 300 mg quetiapine tablets with imprint “E56”?
To determine the manufacturer for “300 mg Seroquel” with imprint “E56,” you need the specific imprint record that matches that imprint to a labeled company (for example, a labeler/market authorization holder or manufacturer listed in the imprint database). I don’t have the underlying imprint-table lookup results included in the information you provided, so I can’t state the manufacturer name with confidence.
If you share your country (or a photo of the tablet markings, including the full imprint text and any scoring), I can help narrow the correct match more safely.
How to verify the manufacturer on the bottle or box (fastest reliable method)
Even when imprints are clear, the most reliable way to confirm manufacturer is the label on the prescription container or packaging. Look for:
- Manufacturer/labeler name on the bottle or carton
- NDC (National Drug Code) number
- Lot number and expiration date
If you provide the NDC from the bottle, I can tell you exactly which manufacturer corresponds to that product (NDC-based identification is much more precise than imprint-only matching).
Patient safety note: why imprint identification can be risky
Imprint codes can overlap across different products or markets, and “Seroquel” can include multiple tablet strengths and versions. Because quetiapine is a prescription medicine, misidentifying a tablet’s strength or maker could lead to dosing errors. Verifying with the bottle/box NDC is the safest approach.
If you want, I can pinpoint it—send one detail
Reply with either:
- The country you’re in, or
- A photo of the tablet showing the full imprint and whether it’s scored, or
- The NDC number from the bottle
…and I’ll help identify the manufacturer that corresponds to “E56” on the 300 mg quetiapine (Seroquel) tablet.
