What do different quetiapine 300 mg “imprints” mean?
For quetiapine immediate-release tablets (and many other tablet strengths), the “imprint” is the set of letters and/or numbers stamped on the tablet. Different manufacturers (and sometimes different product lines) use different imprint codes, even when the tablet strength is the same (for example, 300 mg).
Because the same strength can be made by multiple companies, imprint differences typically help identify the exact product (manufacturer and formulation).
Which quetiapine 300 mg manufacturers use which imprints?
Imprint codes vary by product. To give the correct mapping (imprint → manufacturer), I need the exact imprint you see on your tablet (for example, something like “XX 300,” “A/B,” or a single code).
Quetiapine also exists in different formulations (e.g., immediate-release vs. extended-release). The imprint you see can differ between those versions, so it’s important to match both the imprint and the release type.
How can you identify your exact quetiapine product quickly?
Look closely for:
- The imprint code (letters/numbers on one side, sometimes split across both sides)
- Strength (confirm it says 300 mg)
- Whether the tablet is immediate-release or extended-release (often indicated by brand/formulation name rather than imprint alone)
Then share the imprint exactly as printed (including any letters and numbers) and I can tell you which company’s product it matches.
What if you’re trying to replace it or check if it’s the “same” medicine?
Even when it’s the same drug and strength, imprint differences can correspond to different manufacturers or release types. Substituting between immediate-release and extended-release versions is not the same medication regimen and should be done only with a prescriber/pharmacist’s guidance.
If you reply with the imprint, I’ll map it
Send:
1) The exact imprint on the tablet (both sides if possible)
2) Whether it’s labeled as immediate-release or extended-release (or any brand name you see)
Then I’ll identify the manufacturer associated with that imprint.
