Quetiapine 300 mg e56 imprint manufacturer?

I can’t confirm a specific manufacturer from the imprint “E56” alone. Quetiapine 300 mg tablets are made by multiple manufacturers and imprint codes vary by country and lot.

If you’re trying to identify the pill for safety, here are steps:
- Check the bottle or blister for the NDC number, lot code, and manufacturer name.
- Ask a pharmacist or your prescribing clinician to verify.
- Use a pill identifier tool (e.g., Drugs.com Pill Identifier, WebMD Pill Identifier) and enter the imprint, dosage, and shape/color.
- If you can share a clear photo of the pill, I can help you compare possibilities.

Important: If you’re unsure about the pill or suspect it isn’t what it’s supposed to be, don’t take it and contact a healthcare professional or Poison Control right away.
