How to identify an E56 pill (what’s usually on the imprint)
An “E56” imprint is commonly used to identify a specific prescription tablet strength and formulation. However, the exact drug and manufacturer can vary by country and by who produced the specific generic/brand for that imprint.
Quetiapine 300 mg: does “E56” match?
Quetiapine 300 mg is a common strength of the drug (an antipsychotic). But the imprint “E56” alone is not enough to confirm it is quetiapine in every case, because different manufacturers can use different imprint codes.
What you should check right now to confirm the manufacturer
To reliably confirm that your “E56” pill is quetiapine 300 mg and identify the manufacturer, check:
- The full imprint text exactly as printed (including any side letters/numbers).
- The tablet shape (oval/round), color, and any score line.
- The country/packaging your prescription came from (imprint mapping can differ).
