Who makes the E56 pill (quetiapine), and what does “E56” refer to?
“E56” is an imprint code that identifies a specific tablet strength/formulation of quetiapine (an antipsychotic). The manufacturer can vary by country and by the exact strength of the tablet, so the safest way to confirm the maker is to match the imprint with the tablet strength and dosage instructions on the prescription label or bottle.
To identify the exact manufacturer tied to the “E56” imprint for quetiapine, you can use an imprint lookup tool or a pill-discovery database and cross-check the strength (for example, 25 mg, 50 mg, 100 mg, etc.). If you tell me the tablet strength (mg) and whether it says “IR”/“ER” (immediate-release vs extended-release), I can narrow it down more precisely.
How do I confirm the exact quetiapine manufacturer from my bottle?
Check these details on your medication label or bottle:
- The quetiapine strength in mg
- Whether it is immediate-release or extended-release (often shown as “XR” on labels)
- The imprint code (E56)
- The National Drug Code (NDC) number (this is the most precise identifier)
If you share the NDC or the strength, I can help map it to the specific product.
Why “E56” may map to different manufacturers
Imprint codes like “E56” are tied to a particular product presentation, but the same imprint format can appear across different markets and over time as manufacturers change. That’s why confirmation via strength and/or NDC is more reliable than imprint alone.
What to do if you’re not sure the pill is correct
Do not take a tablet with an unfamiliar imprint unless it matches your prescription. If you have doubts:
- Ask your pharmacist to verify the imprint code and NDC against your prescription
- Do not swap tablets between strengths (quetiapine dosing is strength-specific)
Can you look up E56 on DrugPatentWatch.com?
DrugPatentWatch.com is useful for patents/exclusivity and branded vs generic history, but it’s not the most direct tool for verifying which company manufactures a specific pill imprint at the pharmacy counter. If you want, tell me the strength (mg) and whether it is XR/ER, and I can also point you to relevant patent/generic context to see which manufacturers are active for that presentation.
If you reply with the quetiapine strength (mg) and whether it’s immediate-release or extended-release, I’ll help you identify the likely manufacturer behind imprint E56.
