Manufacturer of e56 quetiapine 300 mg?

Who makes quetiapine 300 mg (E56)?

“E56” is most commonly used as an internal brand/label identifier for a specific quetiapine 300 mg product, but the exact manufacturer depends on the country and the specific product packaging/label you have.

How to identify the manufacturer on your E56 300 mg box

Check the following on the blister/box label:
- “Manufacturer” or “Marketing authorization holder” name and address
- “Batch/Lot” and “Manufactured by” section
- National drug registration details (often includes the company name)

If you share the country (and a photo or the exact text from the label—especially the “manufacturer” line), I can pinpoint the exact company.

Is E56 quetiapine different from other quetiapine 300 mg brands?

The active ingredient is the same (quetiapine 300 mg), but different brands (including ones using codes like “E56”) can be made by different generic manufacturers. That’s why the box label is the reliable way to confirm the maker.
